554 Coleopterological Notices, V. 



This species is possibly the same as that which is identified in 

 our lists as the Colombian brunnipevnis of Marseul ; it differs 

 greatly from brunnipennis, irrespective of color, in its non-inter- 

 rupted apical stria of the pronotum and by the widely interrupted 

 mesosternal stria. 



CARCINOPS Mars. 



This genus is well distinguished from Paromalus by the distinct 

 scutellum and striate elytra. In conjunctus and opuntiae the fine 

 sculpture is very remarkable, the minute punctulation in the former 

 being arranged in short transverse lines, each consisting of two or 

 three minute approximate points, and in the latter, in more rounded 

 clusters of two or three. In some of the allied species the minute 

 punctures, although simple, bear evidence from their somewhat 

 irregular outlines, of being an incipient stage of the clustered points 

 of opuntise. Conjunctus is abundant at Fredericksburg, Virginia 



The species allied to gilensis by the partial obliteration of the 

 subhumeral stria, may be distinguished among themselves as fol- 

 lows : — 



Surface convex, the prothorax longer, barely twice as wide as long. 

 Subhumeral stria obsolete ; size larger, more oblong- elongate. 



gilensis Lee. 

 Subhumeral represented behind by a fine stria or series of punctures. 



Broadly oval ; outer subhumeral at base — near the oblique humeral — 



long and striiform COnsors Lee. 



Narrowly oval, smaller, the outer subhumeral represented at base by a 



deep elongate puncture papagoana n. sp. 



Surface depressed ; size smaller ; prothorax much shorter, more than twice 

 as wide as long COrticalis Lee. 



Corticalis is apparently not the same as tenellus Er., the size 

 being much smaller, and the prothorax is still shorter according to 

 the figure of Marseul. The width given by Marseul for teneltus is 

 1.5 mm., while the largest specimen oi corticalis which I have seen 

 is not more than 1.0 mm. wide; Marseul is however somewhat 

 uncertain in his measurements. Of lJ/-striatys I have a specimen 

 taken in Lake Co., California; it is doubtless cosmopolitan, 



C papagoana. — Narrowly oblong-oval, black, the legs and antennae 

 dark rufous, polished, the minute punctulation sparse, scarcely visible, sim- 

 ple, with stronger sparse punctures only narrowly along the elytral apex and
