380 ENTOMOLOGICAL SOCIETY 



This species is sharply marked by the brown bands and marks 

 of the head, pronotum, and scutellum, and is well separated from 

 the related species with a spot on the cuneus by its broader form. 

 In the shape of its head, pronotum, and scutellum it bears some 

 resemblance to the pale species of the genus Geocoris Fallen. 



Specimens were collected at American Fork, June 22. 



33. Agalliastes decolor. New sp. 



Less robust than A. stigmosus, the male much longer and narrower than 

 the female, beneath black, shining, above chiefly smoky whitish. Head 

 blackish, having a yellowish brown band across the base of the depressed 

 vertex; antennae moderately long, black or fuscous; bucculae and rostrum 

 pale, the latter reaching to the posterior coxae. Pronotum whitish tes 

 taceous, transverse, polished, not conspicuously pubescent, moderately 

 convex, with the callosities prominent and sometimes discolored, the sides 

 oblique. Scutellum with a broad blackish stripe on the middle, bounded 

 at base with yellow. Legs black, the posterior tibiae pale and set with 

 black spines. Middle line of sternum pale piceous. Hemelytra narrow, 

 translucent, finely pubescent, the cuneus marked with a triangular fuscous 

 spot; the membrane faintly smoky, with the veins of the areole white. 

 Abdomen polished black. 



Length to end of venter, ^ 2, 9 if-2 millim ; to tip of membrane, ^ 

 2^, ^ 2 i~ 2 ^ millim; width of pronotum, hardly i millim. 



The delicacy and softness of the hemelytra suggest the inference 

 that the four specimens observed are not mature. These were 

 obtained at American Fork, June 22. 



Other specimens of considerably larger size were collected by 

 Mr. Coquillett near Los Angeles, Cal. 



Two other species of Agalliastes were collected by Mr. 

 Schwarz, the one at Mill Creek on June 16, the other at Salt 

 Lake on June 13, but the specimens will not serve for description. 



ACANTHIID^E. 



1. Piez&stethus californicus Reuter. Monog. Anthocor., 

 1885, p. 600. 



One specimen was secured near Utah lake on June 20. 



2. Anthocoris sp ? 



Two, or perhaps three, species of this genus were collected at 

 Alta and Mill Creek on June 16, 29, and 30. 



3. Lyctocoris sp? 



Forms which appear to belong to two species were captured at 

 Park City on June 17, and at Alta on June 29 and 30. 



4. Triphleps sp ? 



Two species, may eventually prove to become new when more 

 specimens are obtained, were collected, the one at American 

 Fork on June 24, and the other at Wasatch on June 27.
