Hamilton (1969) designated a lectotype for H. analis. Until published, this designation has no validity. The larva was briefly described in a key by van Emden (1938). Map 34. Collection localities of Homoeolabus analis, Genus Attelabus Linnaeus Attelabus Linnaeus, 1758:387; Hamilton 1969:1-04; O'Brien and Wibmer 1982:11. Attelabus contains two widely distributed species in eastern North America and one species confined to Hispaniola. Only one of the North American species occurs in Canada. Description. Dorsal surface of body glabrous. Head stout, quadrate, rarely longer than wide. Eyes large, slightly convex. Rostrum broadly expanded at apex. Antennae (Fig. 164) inserted before middle of rostrum, with terminal 3 segments elongate and more densely pubescent than other segments. Pronotum wider than long, narrower than elytra. Elytra stout, slightly wider than long. T54pe species. Curculio nitens Scopoli, subsequent designation by Voss 1925. Comments. Hamilton (1969) gives keys, descriptions, and references for the two North American species. 180
Attel ab us bi pu stu latus Fabrici us Figs. 11, 164; Map 35 Attelubus 2 -pustulatus Fabricius, 7776:229 (lectotype,'America borealis"; UZMCt. Attelabus bipustulatus: Blatchley and Leng 1916:63; Dillon and Dillon 1961:750; Hamilton 1969:107; Hamilton 1979:30; O'Brien and Wibmer 1982:1,1. Description. Length 2.2-4.5 mm. Body black with reddish orange rectangular markings, these extending from humeri to midpoint ofelytra, laterally to interstria 2 or 3 (variable); ventral surface with a few scattered setae. Head with sides arcuate from base to eyes; surface essentially smooth, with a few very small widely separated shallow points and with 2 deeply impressed arcuate grooves near each eye; median area impressed from area of antennal insertion to above upper level of eyes. Rostrum distinctly shorter than head; surface densely punctured, rugose; apex with lateral angles lacking conspicuous tooth; submental area with conspicuous median tooth (male) (Fig. 164) or swelling (female). Antennae inserted dorsolaterally near base of rostrum. Pronotum 1.4 times wider than long, widest at base; sides arcuate, converging to recurved anterior margin; disc evenly convex, with numerous small, impressed points; interpuncture spaces smooth, shining. Elytra at base 1.3-1.4 times wider than pronotum; apex broadly rounded; striae not impressed, with large, shallowly impressed punctures in regular rows; interstriae about 3.0-4.0 times (variable) wider than striae, with scattered, minute points. Femora of forelegs with 1 small, ventral, peg-like tooth. Distribution. Nova Scotia to Ontario, south through the eastern United States to Florida, west to Wisconsin, Missouri, and Texas. Nova Scotia: Greenfield and Ingramport. Ontario: Blackburn, Constance Bay, Leamington, Normandale, Northumberland, Paris, Pembroke, Sarnia, Sudbury, Toronto, Tillsonburg, andWalsingham. Quebec: Beech Grove, Gatineau Park, and Kazabazua. Comments. Adults of this species are easily recognized by the black body with red humeral areas on the elytra, by the small size, and by the other characters given above in the key and description. Girault (1904) provides some details on the biology. Females cut areas of leaves of various species, oviposit on the apex of the wilted portion, and finally roll it into a firm cylinder containing one egg in its centre. The leaf roll sometimes remains attached to the leaf for weeks. Early summer broods may develop to adults within the leaf rolls while they remain attached to the leaves. In other cases, the leaf roll may fall to the ground a few days 181
