194 THE CANADIAN ENTOMOLOGIST. 



unknown lepidopterous eggs ; probably they were reared from the same 

 host. The species is fully redescribed in the place first cited above, but 

 from the additional tagged specimens I have noted that the body is shiny, 

 the sculpture inconspicuous, distinctly scaly, however, on the mesonotum ; 

 the parapsidal furrows are complete. In black specimens the mesonotum 

 is suffused with yellow sometimes, and in all of the dark variations, the 

 antennae and legs remain unchanged or brownish-yellow. The usual 

 colour, perhaps, is brown. 



TWO NEW GALL MIDGES.

Toxomyia rubida^ n. sp. 

 This species appears to be closely allied to Toxomyia fujigicoia Felt, 

 from which it is most easily separated by its larger size, distinctly darker 

 colour and presumably by a variation in food habit. It was reared 

 February, 191 1, by W. H. Patterson, St. Vincent, W. L, from the 

 aecidiospores of Uro?nyces pisl DeBary on the leaves of Euphorbia 

 pilulifera. 



Male. — Length, i mm. Antennae nearly twice the length of the body, 

 thickly haired, light brown ; 14 segments, the fifth having the basal portion 

 of the stem with a length fully 2^ times its diameter, the distal part with 

 a length 33^ times its diameter, the enlargements globose, each with a 

 rather thick whorl of moderately stout setae and a subapical circumfilum, 

 the loops of the latter extending to the base of the following segment, and 

 as in T. /u?igicolay ih&y 3iYQ produced on the dorsal surface somewhat; 

 terminal segment produced, the basal portion of the stem with a length 

 six times its diameter, the distal enlargement subglobose and apically with 

 long, finger-like process. Palpi : First segment subquadrate, with a 

 length ^ greater than its diameter, the second j^ longer than the first, 

 tapering distally, the third a little longer than the second, more slender, 

 and the fourth ^ longer th^n the third. Mesonotum yellowish-brown, 

 the submedian lines yellowish. Scutellum and postscuteilum yellowish. 

 Abdomen yellowish-orange. Wirigs hyaline, costa light brown, the third 

 vein joining the margin just beyond the apex of the wing, the fifth at the 

 distal third, its branch just before the basal half Halteres yellowish- 

 transparent. Legs mostly pale straw, the distal tarsal segments darker ; 

 claws moderately stout, strongly curved, the anterior unidentate, the 

 pulvilli rudimentary. Genitalia : Basal clasp segment moderately stout,
