THE CANADIAN ENTOMOLOGIST. 271 



Legs black, rarely reddish, thinly grayish dusted ; claws and pulvilli 

 in both sexes short ; hind tibite not ciliate, with a row of bristles of 

 irregular length ; middle tibiae bearing a single macrochieta on the front 

 side near the middle. 



Wings hyaline, subcosta entering costa at an acute angle, third vein 

 with a single long bristle at base, anterior end of median cross-vein at end 

 of tirst third of the distance from the radio-medial cross-vein to the bend of 

 Mi^.2 ; Mi^2 entirely wanting beyond the bend ; calypteres whitish. 



Abdomen black, polished, only the narrow bases of the segments 

 white pollinose, the fasciae generally interrupted medially ; first three 

 segments with marginal and fourth with discal and marginal macrochaetae ; 

 abdomen with many rather strong bristly hairs, mostly appressed, when 

 erect having in some specimens the appearance of discal bristles : hypo- 

 pygium black, polished, thinly dusted with grayish pollen. Length, 

 2.5-3 ^^' 



Described from 15 males and 13 females, as follows : i female from 

 Bisc. Bay, Fla., Mrs. Slosson coll.; i male bred by Mr. A. Busck from 

 Aristotelia 7'oseosuffusella Clemens, issued July 28, 1902 ; 2 males and 5 

 females, Nos. i6a and i6aa, labelled " par. on Tineid of Z'. australis, iss. 

 Feb. 20, 21, 1880"; 12 males and 7 females, G. M. L., No. 2267T, bred 

 from larvae of Paralechia pi?ufo/ie//a Chamb., infesting leaves of Pimis 

 rigida. ^L^terial collected by Mr. W. F. Fiske near Lowell, Mass. 

 Type, I male and i female from the last mentioned series, Gipsy Moth 

 Lab., No. 2267T. Type No. 13398, U. S. N. M. 



Schizotachina co?ivecta Walker. (Fig. 3, wing.) 

 There seems to be no doubt that the specimens in the U. S. N. M. 

 collection, which remain after the separation of S. vitinervis, represent the 

 species described by Walker. In the wings of typical specimens the 

 subcosta enters the costa perpendicularly, and the position and inclination 

 of the median cross-vein are as shown in the accompanying figure ; the 

 facial ridges are strongly ciliate on almost the lower two-thirds, and the 

 third aristal segment is twice as long as the second. However, among 

 the half dozen specimens I have examined, I find some which have the 

 facial ridges ciliate on only the lower third. The median cross-vein varies 

 in position from one-third to one-half the distance from the radio-medial 

 cross-vein to the bend of vein Mi. a- Vein Mi^2 Js always quite distinct to 

 the margin of the wing, but the close relation of the species to vitinervis 

 is evidenced by the fact that the part of the vein beyond the bend is 

 weaker than the penultimate section. I have, therefore, refrained from
