broader and shorter than in the male. Hind femora long and 

 much flattened. 



Male genitalia small ; dextral hook about twice longer than its 

 basal width and tapering to a point; sinistral oval and lying 

 along the sinistral notch. 



Color greyish-testaceous; callosities narrowly black; disk of 

 pronotum with two broad fuscous rays more or less distinct. 

 Scutellum infuscated or almost black. Elytra dotted with san- 

 guinous on cuneus and sometimes more sparsely on corium and 

 clavus. Membrane deeply infuscated, nervures pale dotted with 

 red. Wings somewhat infuscated, with blackish nervures. Body 

 beneath infuscated. Antennae and legs pale, femora dusky, hind 

 pair more or less dotted with red points; tarsi black at apex. 

 Antennae .slightly infuscated toward their apex. Upper surface 

 clothed with minute silvery pubescence, obscurely arranged in 

 lines M'hich are more distinct on the head, where they form tliree 

 longitudinal vittae. 



Described from numerous examples beaten from chaparral in 

 San Diego County, California, at Coronado, National City, 

 Alpine, etc., in May and June. 



At first sight this species seems very different from scurrilis, 

 but a closer inspection shows that it possesses similar generic 

 characters and there can be no doubt that it should be placed in 

 the same genus. 



Parthenicus picicollis n. sp. 



Allied to jjsalliodes, but with pronotum, scutellum and com- 

 missure piceous or almost black ; beneath more or less infuscated, 

 above pale, more or less closely dotted with sanguineus points, 

 elytra appearing dark red ; membrane black. Length 3 mm. to 

 tip of membrane. 



Head vertical; vertex and front conjointly flattened above, a 

 very little convex below, base of vertex eearinate. Clypeus 

 prominent, but somewhat less so than in Macrotylus, its base 

 well distinguished and distinctly above line of antennae. Eyes 

 large, prominent, projecting for nearly their whole width beyond 

 the pronotal angles; viewed from the side broad-oval, vertical, 

 reaching almost to gula, face but little prominent before the eyes, 

 almost half of this being projection of clypeus. Antennae rather 

 short, first joint but little surpassing clypeus; second longer than 

 l)asal margin of pronotum. Pronotum moderately convex, cal- 

 losities small and little elevated, distinguished behind by a deeply 

 incised line. Basal lobe of scutellum covered. Costal margin of 

 elytra feebly arcuated. Cuneus about as long as wide at base in
