hind and meets an obtuse tooth on the upper lateral margins of the py- 

 gofers. Sinistral hook rather broad, curved and following the ventral 

 wall of the pygofer, its apex not disclosed in any specimen before me but 

 apparently obtuse. 



Color deep dull black. Venter in clearly marked examples with an 

 elongated fulvous mark against each eye and an indistinct longitudinal 

 median vitta, but generally these markings are more or less obsolete ; 

 cheeks sometimes obscure rufous. Pronotum pale yellowish, more or less 

 tinged with fulvous or rufous, including the raised anterior margin ; callo- 

 sities and the area between them black, the disk posteriorly sometimes 

 suffused with blackish. Closed elytra with a broad diffuse commissural 

 vitta which usually fades out on the base of the clavus. Scutellum. mem- 

 brane, legs, antennae and lower surface deep black, the disk and sides of 

 the venter sometimes becoming reddish ; apex of the dextral genital hook 

 conspicuously pale. 



Described from seven males and four females taken by Mr. 

 Giffard at Seattle, Wash., July 7, 1917. 



Holotype (No. 342), male, in collection of the California 

 Academy of Sciences. 



Allotype, female, in the collection of Mr. Giffard.

137. Lopidea ampla, new species 



Closely allied to aculeata; larger with more conspicuous black hairs 

 above and with the elytral costa distinctly bowing and different male geni- 

 talia. Length 7-7J/2 mm. 



Vertex flattened posteriorly with the basal carina sharp, not reaching 

 the inner angle of the eyes. Antennae longer and stouter than in aculeata; 

 the first segment distinctly longer and thicker; third about two-thirds the 

 length of the second. Pronotum and callosities shaped as in aculeata. 

 Elytra wider than in aculeata, the costa regularly and distinctly arcuated; 

 width when closed 2 mm. at base and Z'-^ mm. at widest point; clavus 

 distinctly wrinkled or shagreened, giving the elytra a rougher aspect than 

 in aculeata. Whole surface of insect rather closely clothed with stiff black 

 hairs, which spring from punctures that are frequently fuscous or black; 

 these hairs are especially long and thick on the head and pronotum and 

 are much more conspicuous on the elytra than in aculeata. 



Dextral hook of the male genitalia broad, a little constricted before the 

 rounded depressed apex ; this flattened apex is sometimes paler in color 

 and may have its superior angle slightly produced; the tooth-like dorsal 

 projection on the dextral margin of the pygofer is shorter and more 

 obtuse than in aculeata. Sinistral hook broad and curved, its apex ex- 

 panded, bifurcated and somewhat twisted. 



Color deep opaque black ; posterior one-half of the pronotum, including 

 the depressed sides, and broad costal margin of the elytra, yellowish tes- 

 taceous ; narrow hind edge of the pronotum and sometimes its n«edian 

 line fuscous; hind edge of the ventral segments narrowly whitish. 



Described from numerous specimens representing- both 

 sexes taken by Mr. Giffard on Vicia gigantea at Lands End, 

 San Francisco, July 24, 1917; and a good series from Seattle, 

 Wash., taken July 7, 1917. In my own collection is a male
