Vol. XI] VAN DUZEE—NEW HEMIPTEROUS INSECTS 133 



Head with eyes about as wide as base of pronotum; vertex distinctly more 

 convex than in suavis, with a nearly obsolete median sulcus; surface more 

 dull and clothed with a shorter pubescence than in its ally. Male claspers 

 formed as in suavis, the sinistral shorter and thicker. 



Color, deep black, moderately polished; membrane uniformly infuscated ; 

 antennae pale yellowish white becoming dusky on segments III and IV, basal 

 two-thirds of I and narrow base of II black; femora black, tipped with 

 white; tibiae white strongly dotted with black at base of the black spines; 

 tarsi whitish, the apical segment and claws blackish. 



Described from seven males and three females taken by 

 me at Alpine, San Diego Co., Calif., April 22, 1913. More 

 recently Mr. Ralph Hopping has sent me a series of 15 

 taken by him at Mohave, Calif., May 3, 1919. Easily 

 recognized by the pale antennae and white legs with black 

 femora and tibial dots. In this and the allied species the 

 second antennal segment is thicker in the male. 



Holotype, male, from Alpine, and allotype, female, in 

 collection of author; paratypes in his collection and that of 

 the California Academy of Sciences. 



Type locality, Alpine, San Diego County Calif. 



28. Merragata slossoni, new species 



Narrower and paler than hebroides White, with the an- 

 tennae and legs more slender and less hirsute, apex of scutel- 

 lum bifid. Length 1 Y4 mm. 



Head more tumid on base of vertex than in hebroides, elevated above 

 line of the ocelli by more than twice the diameter of the ocelli, the contour 

 more convex when viewed from the side; above with a shallow median 

 sulcus; antennae nearly twice length of head as seen from above, segments 

 I and II equal, I almost attaining apex of head, III shorter, IV fusiform, 

 considerably longer and thicker than II but notably thinner than in hebroides; 

 rostrum passing hind coxae, segment I attaining anterior line of eye, II the 

 anterior line of front coxae, and III the middle of the mesosternum. Pro- 

 notum hardly twice wider than long, deeply constricted between the lobes, 

 the median sulcus deep and passing anterior one-half of posterior lobe; 

 collar distinct, distinguished behind by a line of deep punctures, a 

 similar line following the posterior submargin, otherwise impunctate. Scutel- 

 lum with a distinct median carina basally, its apex obtusely bifid. 



Color, pale castaneous becoming almost black on scutellum, vertex and meso- 

 and meta-pleurae, the middle of vertex broadly, and a large lobate spot 

 covering much of the posterior lobe of pronotum, paler or fulvo-testaceous. 

 Elytra pale at base, infuscated toward apex, claval area entirely and an 

 interstitial line on the corium white; membrane pale fuscous with four white 

 spots, one basal, one elongated, at apex, and one either side at apex of 

 corium ; antennae and legs pale yellowish testaceous, the apical segment of 

 the former darker; apex of tarsi infuscated, the claws pale; rostrum pale 

 becoming blackish at apex; pronotum sparsely clothed with soft pale hairs; 

 thickened portion of corium and vertex with soft white pubescence, the de- 

 pressions on pronotum and the pectus pruinose.
