Allied to C. americanus Or.-, but at once distinguished from it aud 

 the closely allied forms by the black wings. 



Cryptus leucopus sp. nov. 



Male. — Length 14 mm . Entirely black: the anterior legs beneath 

 and anterior aud middle knees rufous ; a line on anterior trochanters 

 beneath, aud extreme base of all the femora, and the apex of second 

 joint of all trochanters, yellowish; the four terminal joints of posterior 

 tarsi, white. Head, trausverse, punctate, the forehead concave, rugulose; 

 the anterior orbits from base of antennae to base of maudibles, the 

 clypeus, mandibles, except at base and the teeth, the second joint of 

 labial palpi outwardly, and a line on the third joint, yellowish-white. 

 Thorax punctate, with deep, distinct parapsidal grooves; the pleura 

 and metathorax rugose, the latter without any distinct keels. Abdo- 

 men, except petiole, dark rufous, alutaceous. Wings hyaline or 

 slightly discolored ; stigma and veins black, some of the veins being 

 dark piceous; the areolet is large, pentagonal, the cubitus with a 

 stump of a vein at the middle. 



Habitat. —Colorado. 



Described from one specimen. 



This species, in stature, resembles C. robustus Cr., but the color of 

 the legs and abdomen readily distinguish it. 



Cryptus alamedensis sp. nov. 



Female. — Length 10 mm ; ovipositor, 4 mm . Stature and general appear- 

 ance of C. limatus Cress. Head, thorax, antenna?, ovipositor, all coxa?, 

 the first joint of all trochanters," and the terminal joint of all tarsi, 

 black ; legs and abdomen rufous ; the anterior tibia? are very short and 

 abnormally thickened, constricted at base, the posterior tibia? behind 

 and the basal joint of tarsi fuscous. Head transverse, punctate, be- 

 low the ocelli more coarsely continently punctate; posterior orbits, 

 anterior orbits, interrupted opposite the antennae, and the clypeus, yel- 

 lowish ; palpi mostly black. Thorax punctate, the parapsidal grooves 

 not sharply defined ; the upper margin of collar lined with white but 

 widely interrupted in the middle ; tegulse, except a white spot at base, 

 black; a dot beneath the teguhe and the post-scutellum, white; pleura 

 and metathorax rugose, covered along the sides with a white, glitter- 

 ing pubescence, the metathorax is rounded off behind and has but one 

 poorly defined transverse keel. Wings hyaline; stigma and veins 

 piceous black ; the areolet pentagonal, the cubitus without a stump of 

 a vein, and the submedian cell shorter than the median. 



Habitat. — Alameda, CaL 



Described from one specimen received from Mr. Albert KcebeJe, 

 reared during April, 1887, from an unknown lepidopterous cocoon.
