species, as the galls are not those of salicis-ovum, but of the coopera. 

 group. 



5. Cryptocampus salicis-ovulum (Walsh). 



Enura salicis-ovulum Walsh, Proc. Ent. Soc. Phil., vi, 1866, p. 253 [original 



description in which only the gall and larva are described]. 

 Crvplocampus salicis-ovuhim Dalla Torre, Cat. Hym., i, 1894, p. 278. 



This species was described from the gall and larva. The gall is 

 like ovian Walsh, but is found on Salix hiuiiilis. The larvae differ in 

 color from those oi s.-ovuni. 



This may be a distinct species, but it is quite probable that it is 

 merely s. -ovum. Till it is bred and the adult compared it will stand as 

 a hindrance to workers. I do not think, however, it should be en- 

 tirely overlooked, as some workers have been inclined to do. 



6. Cryptocampus albirictus (Cresson).

Enura albiricta Marl., Tech. Ser. 3, U. S. Dept. Ag., p. 20, 1906. 



Female. — "Shining black; head broad, posterior orbits Hull testaceous; spot 

 beneath eyes, clypeus, labrum, and mandibles, except tips, pale testaceous; wings 

 hyaline, iridescent, base of stigma pale ; tegulae and legs pale testaceous, middle of 

 femora more or less, tips of posterior tibiae and tarsi except base, blackish. Length 

 .15 inch" (4 mm.). Original description. 



Habitat. — Nevada (Morrison); Washington (Kincaid). 



I have not seen the above species. There is a specimen in the 

 Colorado Agricultural College collection which was labeled albiricta 

 with a query. It has the posterior orbits black, no pale spot beneath 

 the eyes ; base of stigma black, subopaque ; length 5 mm. It is prob- 

 ably a good species. It was collected in Larimer Co., Colo., July 2, 

 1896, by Prof. C. P. Gillette. 



7. Cryptocampus insularis (Kincaid). 



Enura insularis Kincaid, Proc. Wash. Ent. Soc, 1904, p. 352. 

 Cryptocampus insularis Konow, Genera Insectorum, I905, p. S'- 

 '■'■ Female. — Length 4.5 to 5 mm.; slender, shining; clypeus very deeply and 

 narrowly emarginate ; ridges about ocellar area distinctly raised, but rounded ; frontal 

 crest broad, rounded, with a narrow notch in the middle; antennal fovea" (middle 

 fovea) " small, circular, moderately excavated ; antennas short, slender, third and 

 fourth joints subequal ; outer veins of discal cells in hind wings interstitial ; stigma 

 rounded at base, tapering to an acute point ; tarsal claws slender, subequal ; sheath 

 stout at base, rather sharply rounded at apex. Color black ; labrum, base of mandi- 

 bles, tips of coxae, trochanters, tips of femora, tibiee except apices of posterior pair, 

 and anterior and middle tarsi, testaceous.
