240 University of California PuUications. [Entomology 



a few were swept from weeds near the lake. The males scarcely 

 differ from the females and in both sexes some individuals are 

 paler or reddish. The pronotum and parts of the elytra that 

 are gray in the black form are ferruginous in the pale, but most 

 of the material taken answers in every respect to the excellent 

 description given by Dr. Uhler. 



Coquillettia insignis Uhler. Three males of this pretty species 

 were swept from weeds near the sawmill on Fallen Leaf Lake, 

 July 25, and one was taken next day from the w-estern slope of 

 Angora Peak above 8000 feet. 



Dicyphus calif ornicus Stal. A few were taken about Fallen 

 Leaf Lake late in July. 



Dicyphus agilis Uhler. With the preceding but more abun- 

 dant. I distinguish this from calif ornicus by its larger size, paler 

 colors, the almost entire want of red on the elytra, the more 

 tumid and exposed base of the scutellum and especially by the 

 shorter basal joint of the antennae. 



Dicyphus vestitus Uhler. One example was taken July 17 

 near the lower end of Fallen Leaf Lake. 



Dicyphus crudus, new species 



Form and size of agilis; pale greenish-white. Length 5 mm., width 

 across the elytra little more than 1 mm. 



Vertex less swollen than in agilis, eyes a little more prominent, with 

 antennae longer and prouotal collar more elongated. Elytra very long, 

 parallel, membrane surpassing abdomen by two-thirds its length. 



Color pale greenish-white, deeper green on anterior lobe of pronotum, 

 pleural pieces and base of scutellum. Eyes and tips of the tarsi black. 

 Neck with a fuscous cloud behind each eye. Elytra almost pellucid, 

 sparsely clothed with short apressed white hairs. Membrane with a faint 

 longitudinal dusky cloud behind the areoles. Arolia long, lying near the 

 small claws. Apical joint of the antennae, oviduct and genital segment 

 of the male slightly embrowned. 



Described from one pair taken on the flats near the lower end 

 of Fallen Leaf Lake. This insect might be taken for the im- 

 mature form of agilis were it not for the longer elytra, broader 

 collar and flattened vertex. The fuscous cloud behind the eyes 

 is also distinctive. 



Lahops hesperius Uhler. One example was taken July 31 on 

 the shore of Lake Tahoe near the Hotel Tallac.
