and of pale setae. Frons convex, with median longitudinal groove
absent or only weakly evident. Rostrum flattened, with only weak trace
of elevated carinae; surface obscured by dense, white, recumbent setae.
Pronotum about 1.3 times wider than long, widest behind middle,
essentially as in Z fasciatus; W-shaped median groove less deeply and
sharply impressed. Elytra about 1.5 times longer than wide; apex
broadly rounded; striae and interstriae as in I fasciatus, except
interstriae 5 and 7 not elevated; interstria 3 weakly to distinctly elevated
in white patch. Pygidium vertical; apex narrowly rounded.
Distribution. Eastern Canada, south to New York. Ontario:24
miles north of Parry Sound. Quebec: Beechgrove.
Comments. This rather poorly differentiated species closely
resembles T. fasciatus. Adults of T. latifascia differ from those of
T. fasciatus by the characters summarized in the key. Nothing is known
ofits life history or habits, and no host has been recorded.
Genus Allandrus LeConte
Allandrus LeConte, 1876: 396; Valentine 196O:7 7 .
Only three North American species are contained in this genus; all
three occur in Canada. This genus is characterized by widely separated
and protuberant eyes (Fig. 28). The minimum distance between the eyes
is always greater than the minimum width of the rostrum near the base.
Other features that serve to characterize this genus are the flat,
spatulate rostrum (Fig. 28), the strongly elevated antebasal pronotal
carina (Fig. 32), and the reticulate-punctate pronotum. Valentine
(1960) discusses the genus and gives a key to the North American
species.
Description. Pubescence abundant. Head not retractable.
Rostrum prolonged, constricted at base; sides strongly diverging; apex
broadly expanded. Antennae inserted on lateral surfaces of rostrum;
insertion remote from eye. Eyes lateral, slightly oval, with entire
margins; distance between eyes greater than rostrum width at base.
Pronotum (Fig. 32) wider than long; surface punctate-reticulate; lateral
margin without carina except at posterior angle; antebasal carina
strongly elevated, transverse to weakly emarginate, curved slightly at
basal angles. Elytra with sides parallel; apex broadly rounded; striae in
regular rows, weakly marked with shallow punctures.
T5pe species. Allandrus bifasciatus LeConte, monotypic.
