I am unable to detect any sexual differences in the specimens before 

 me, the last abdominal segments of the dorsal and ventral aspect being 

 oval at tip. 



There is considerable variation in the color of the elytra, although the 

 type of coloration is preserved. In those fully colored about one-fourth 

 at base is piceous, then a broad pale band, following the latter another 

 broad piceous band, the tip for about one-fourth is pale. The tendency 

 is to become paler. The basal piceous band is gradually lost, then the 

 post-median piceous band becomes narrower so that the elytra are finally 

 rufo-testaceous with a very narrow piceous band behind the middle. 



This species belongs in our series ne-Av pvncticollix, and differs in its 

 longer thorax, less coarsely punctured elytra and different coloration. 



Occurs in southwestern Texas.

 This is the species referred to by me but not named (Trans. Am. Ent. 

 Soc. V, p. 2H0). It is closely allied to fvscnla Lee, and differs in the 

 presence of the sub-apical pale spot. The variety referred to by Mr. 

 Grorham as having no apical spot is without doubt the true fiisaiJa Lee. 

 If the two forms are really identical the latter name should prevail. 



C sirpata n. sp. — Form slender, piceous, legs and antennae brown, elytra 

 testaceous with piceous fasciffi. Antennae slender, brown, joint 2 not longer than 

 half the third,. joints .3-10 subequal, 11 longer. Head coarsely, deeply and mod- 

 erately closely punctate, sparsely pubescent.. Thorax cylindrical, nearly twice 

 as long as wide at apex, slightly contracted behind the apex and more decidedly 

 compressed on each side behind the middle, surface coarsely, moderately closely 

 punctate, sparsely pubescent, ante-scutellar impression feeble. Elytra wider than 

 the thorax, humeri distinct, sides straight, very slightly divergent, apices con- 

 jointly rounded, disc with rows of coarse moderately closely placed punctures 

 which become gradually finer toward the apex but do not reach the tip. intervals 

 much wider than the punctures with a row of fine punctures, sparsely pubescent ; 

 color pale testaceous, humeral umbone piceous, a narrow piceous fascia one-third 

 from base which extends along the suture to the scutellum and along the lateral 

 margin to the base, a broad piceous fascia behind the middle with the anterior and 

 posterior margins undulating, about one-fifth of the elytra at tip is testaceous. 

 Body beneath piceous, abdomen sparsely punctate. Length .32-.38 inch ; 8-9.5 mm. 



Male. — Fourth ventral segment densely punctured at middle, fifth very feebly 

 eraarginate, sixth shorter truncate at tip and deeply longitudinally sulcate at mid- 

 dle: last doj-sal narrower than the last ventral, oval at tip and entire. 



Female. — Last ventral very short oval, last dorsal narrower oval at tip. 



This is also one of the species merely indicated by me (Trans. Am. 

 Ent. Soc. V, p. -3U), but not fully described from the absence of the 

 male. In its general appearance it resembles undnlafa, and might 

 readily be considered a color variety, but the structure of the antennae
