angles distinct, not prominent, disc regularly convex, moderately coarsely closely 

 punctate. Elytra a little wider at base than the thorax, humeri obtuse, sides 

 nearly parallel, gradually narrowed at apical third, conjoined apices obtuse, 

 surface closely punctate, but less coarsely than the thorax. Body beneath darker 

 seneous, densely and moderately coarsely punctate and densely clothed with 

 cinereous-white recumbent pubescence. Legs yellowish testaceous. Length 

 .30 inch.; 7.5 mm. 



The male has the fifth v^entral l)roadly einarginate, the sixtli deeply 

 triangularly incised. The hind tibise are slightly arcuate. 



At first sight this insect would, in all probability, be mistaken for 

 a Glj/ptoscelis ; such was the impression made upon myself 



Occurs near Los Angeles, Cal. Taken by Mr. D. W. Coquillett. 



AGALISSUS Dalm. 



A. chaniseropis n. sp. — Black, shining, elytra dull red with the suture 

 piceous, thorax with four longitudinal lines of white pubescence. Head coarsely 

 sparsely punctured at middle, eyes completely encircled with white recumbent 

 pubescence, which extends along the sides of the front and crosses the edge of 

 the clypeus. Thorax as wide as long, slightly narrowed in front, sides feebly 

 arcuate, disc coarsely sparsely punctate, with four shallow longitudinal grooves 

 extending from apex to base, the two inner grooves interrupted near the base, 

 the grooves densely pitted with white recumbent pubescence: scutellum semi 

 circular, black, glabrous. Elytra wider at base than the thorax, gradually 

 arcuately narrowed to apex, apices rotundate-truncate, the sutural spine short, 

 more distinct in the male, disc vaguely grooved each side of suture, surface 

 moderately coarsely, not closely punctate, each puncture with a short, semi- 

 erect cinereous hair, color dull red, the suture gradually more widely piceous 

 from the base, then more rapidly narrowing at the apical third. Body beneath 

 black, shining, sparsely punctate; propleurae, sides of metasternum, outer edge 

 of met-episterna and a triangular spot at the sides of each ventral segment with 

 white pubescence. Legs black, sparsely pubescent. Length .76 — .83 inch. ; 19 

 — 21.5 mm. 



In the male the antennse reach the middle of the body, in the 

 female shorter, otherwise, excepting the slightly more slender form 

 of the male, there is no marked sexual difference. 



In this species the sides of the elytra behind the humeri are as 

 deeply emarginate as in gratus. The differences between the genera 

 Agalissus and Zagymnus seem to be measurably reduced by the dis- 

 covery of this species. The front is less oblique than in the former 

 as typified by gratus, and not quite vertical as in Zagymnus. The 

 apices of the elytra more nearly approach in form the latter genus. 

 The only remaining character seems to be that in Agalissus the form 

 of body is narrowed behind, while in Zagymnus it is nearly parallel.
