parallel and straight at the sides except near the apex ; border rather thick ; 

 fifth segment longer. Legs short ; posterior tihise swollen toward apex, slender 

 near the base, the tarsi scarcely three-fifths as long. Length 2.7-3.0 mm. ; 

 width 0.55-0.6 mm. 



Texas (Austin). 



The male has a strongly elevated carina at the middle of the first 

 dorsal, becoming gradually feebler and ending at the basal impres- 

 sion ; at apex it projects slightly beyond the margin ; there is also 

 a very small carina near the base of the fifth. 



In both of these species the fourth antennal joint is distinctly 

 shorter than the fifth ; in obscura, however, these two joints are 

 subequal. The present species, although closely allied to valens, 

 differs greatly in the longer basal joint of the antennge, form of the 

 prothorax, sparser elytral and much finer and sparser abdominal 

 punctuation, and in its smaller size and more slender form. Three 

 males, exhibiting no variation. 



G. o"bsClira n. sp. — Depressed, rather wide, blackish, the pronotum 

 slightly, the elytra distinctly, pale ; abdomen scarcely paler toward base but 

 with the tip flavescent ; legs pale ; antennae not distinctly paler toward base ; 

 anterior parts extremely minutely, rather densely punctate, somewhat strongly 

 shining, finely, densely pubescent ; abdomen more strongly, rather closely, 

 evenly punctate, with longer and somewhat sparse but distinct pubescence. 

 Head a little wider than long, distinctly shorter but only slightly narrower 

 than the prothorax, the neck one-half as wide as the width across the eyes, 

 the latter at fully their own length from the base ; antennae slender, fully as 

 long as the prothorax and elytra, equal in width from the fourth joint, the 

 first three greatly elongate, the first longer, second and third equal, fourth 

 scarcely visibly shorter than the fifth, fourth to tenth obconical, longer than 

 wide, the tenth fully as long as wide, eleventh slender, pointed, not quite as 

 long as the two preceding. Prothorax very slightly wider than long, the sides 

 rounded and convergent in apical third, the apex more feebly arcuate in the 

 middle ; sides straight and just visibly convergent in basal two-thirds, the 

 base broadly, distinctly arcuate ; basal angles obtuse and distinct ; disk even, 

 not perceptibly impressed. Elytra quadrate, one-third longer and wider than 

 the prothorax, parallel and straight at the sides, with the humeri exposed at 

 base ; disk impressed on the suture behind the scutellum. Abdomen distinctly 

 narrower than the elytra, as long as the anterior parts ; sides parallel and 

 evenly, just visibly arcuate; border strong; first four segments equal and 

 nearly flat ; fifth one-half longer. Length 2.9 mm. ; width 0.65 mm. 



California (Pomona). Mr. H. C. Fall. 



The truncate sixth ventral plate would seem to indicate the male, 

 but there is no trace of the dorsal carinee so well developed in the 

 two preceding species, and the present differs also in its more
