THE CANADIAN ENTOMOLOGIST. 21 



Legs entirely black, the brown pulvilli as long as the last 

 tarsal joint on all the feet; middle tibia with one long spine below 

 its middle on outer front side, and usually a small one above it; 

 hind tibia with slightly uneven row of small bristles on outer hind 

 side, one below middle being larger. 



Wings almost hyaline; third vein with one or two hairs at 

 base; fourth vein with rounded, oblique curve; apical cell open 

 some distance before wing tip (more than half the distance separating 

 tips of second and third); hind cross-vein rather oblique and bowed 

 outwardly. Apical cross-vein parallel with hind margin. 



Female — Front at narrowest compared with entire width of 

 head gives in 5 specimens .360; .345; .327; .303; .322— average, 

 .331. Parafrontals wider than stripe; third antennal joint about 

 three times as long as second; above vibrissse only a few small 

 hairs; pulvilli short. Hairs of head, scutellum and abdomen not 

 so long and erect as in male; middle tibia with two spines on outer 

 front side. 



Length 4.7 to 6.3 mm. 



Described from nine males and five females, reared by Prof 

 Lawson Caesar from Archips argyrospila at Simcoe, Ont.; dates 

 of emergence, July 1 to 15, 1915. 



I dedicate the species to Mr. Caesar, and follow the example of 

 Linnaeus (in Liicilia ccesar) in leaving the specific name in apposition 

 in the nominative case, instead of giving it a genitive ending. 



Two specimens of each sex, including the type male, will be 

 deposited in the Canadian National Museum; the remainder will 

 be at the disposal of Mr. Caesar, 



Frontina spectabilis, n. sp. 



Female — Easily recognized by a dense coating of golden 

 pollen, which uniformly covers the upper portions of head, thorax 

 and abdomen, except that it is less distinct on the first abdominal 

 segment. 



Front of vertex, when viewed from above, as wide as one 

 eye (.333 of entire head by micrometer measurement); ocellars and 

 orbitals normal, proclinate; the frontals form a row of 7 (not
