This genus has the form and aspect of Phytocoris, but the 

 entire absence of a pronotal collum, the short basal joint of the 

 antennae and the strongly compressed and arched clypeus seem 

 to warrant its separation. It has much the aspect of the Mirince 

 but the non-sulcate vertex, elongated anterior coxae and short 

 basal joint of the tarsi exclude it from that division. 



Argyrocoris scurrilis n. sp. 



Testaceous white; pronotum with five lines of appressed 

 silvery scales the three median of which are continued over the 

 head. Length 5 mm. 



Vertex viewed from above oblong, a little longer than broad between 

 the eyes; clypeus abrupt, narrow, viewed from the side forming a semi- 

 circular plate distinctly wider than the narrow cheeks and lorse. Eyes 

 castaneous. Basal joint of the antenna; surpassing the clypeus by about 

 one-third of its length, attenuated on its immediate base, a little thicker 

 than the second; third about two-thirds the length of the second; fourth 

 short and feeble, not half the length of the third and much thinner, hardly 

 so long as the first. Callousities of the pronotum obsolete. Elytra long, 

 parallel, surpassing the tip of the abdomen by practically the whole length 

 of the membrane. Hind femora much compressed, ligulate, regularly nar- 

 rowing from near the base. 



Color whitish testaceous, clothed with scattering soft white hairs. 

 Pronotum with five slender longitudinal lines of brilliant silvery-white 

 appressed scale-like hairs, the three median of which are continued on the 

 head and are connected behind by a similar line across the base of the 

 scutellum ; the pronotal lines more or less distinctly margined with fuscous. 

 Scutellum somewhat infuscated at base, the broad median line and slender 

 margins silvery pubescent. Elytra nearly uniclorous. Membrane white, 

 sparingly marmorate with fuscous beyond the areoles. Legs concolorous, 

 the hind femora with three longitudinal black lines below, which are more 

 or less visible above. Tarsi slightly infuscated, the claws black. 



Described from three examples taken at light in the Hua- 

 chuca Mts., Arizona, in July, by Prof. H. G. Barber. 



Eustictus venatorius n. sp. 



Closely allied to g) ossits but of a yellowish-testaceous color 

 mottled and dotted with fuscous or black. Length 7 — 8 mm. 



Head as in grossus; exerted base polished black with a fulvous spot 

 behind the inner angle of each eye; surface pale clouded with fuscous 

 between the antennae and more indistinctly on the vertex; cheeks polished 

 black ; throat blackish. Antennas pale closely dotted with black ; tip of 

 the second joint and apical one-half of the third whitish; fourth joint 

 black, the extreme tip paler. Pronotum coarsely punctured, variegated, 

 anteriorly mostly black, posteriorly largely pale. Scutellum black; a large
