442 Johan Andersentral side of the eighth abdominal segment is given as it was oftendifficult to count them. I do not gve the total size of the larvaesince this varies greatly according to their state. Instead I haveused the length (along the median line) and width of the craniumas it is little influenced by the state of the larva.Description of the speciesB. argenteolum.Material: 22 third stage larvae, 4 taken in STi: Melhus 15.7-17. 7. 64, one taken in STi: Gaulosen 28.7.62, whereas the restof the larvae were reared, first seen between about 7.7 and 10.8in the years 1963- 1965. 8 first and 24 second stage larvae fromrearing, first stage first seen between 10.6 to 10.7 1963 and 1965,and second stage from about 18.6 to 3.8 1963-1965. The adultscollected in STi: Melhus and Gaulosen.T h i r d s t a g e (Head and prothorax Plate I,3)Length of head: 0.72-0.82 mm, width : 1.15-1.30 mm.Head and thorax pale yellow or yellowish white. Hind andcentral parts of head, middle and outer parts of mandibles togetherwith retinaculum, a large triangular area on pronotumand a little spot on each side of meso-and metanotum more orless pale brown. So are the two outer joints of the antennae oftenas well. Abdominal tergtes monochrome, only a little darkerthan the lightest parts of head and prothorax. Ventral side ofhead and prosternum light orange, rest of ventral side paleyellow or yellowish white. Ocellar area black.Head broad: ee:OO = 0.59-0.68. Epicranial suture veryshort, distinctly shorter than basal joint of outer lobe. Ocellilarge, carried by an ocellar area noticeably projecting from sidesof head capsule. Three setae on ocellar area. Frontal piece with7-13 large setae in the area within and a little in front of ocelli(in addition to one seta somewhat behind the basis of tentorialrib on either side). In addition the head has micropores partlynearly visible at 50 X magnification. Head shiny, hind partwith fish-scale like sculpture clearly visible at 25 X. Nasale(Fig. 2) clearly projecting beyond the corners of adnasalia, thelatter very little protruding. Front margin of adnasalia oftennearly parallel with the almost straight front margin of nasale.Latter sometimes slightly concave, seldom convex, broad (a:b= 0.30-0.40), usually more than twice as long as the epicranialsuture. Margin of nasale and adnasalia always more or less serrated,often very distinctly denticulated. In the first, number ofteeth 8 to more than 18. Antennae (Fig. 8) relatively slender,second joint usually more than twice, but less than 2.5 times, as
