AMERICAN COLEOPTERA. 89 



Lower California (El Taste, San Felipe, Santa Rosa, San 

 Jose del Cabo). All specimens seen collected by Mr. Beyer. 



The specimens here referred are quite variable in two or 

 three particulars, but I think there is little doubt of their 

 identity. The width of the front between the eyes varies 

 from two to three times that of the eye as viewed from the 

 front. This difference is of course fundamentally sexual in 

 nature, but there is evidently some little variation in the same 

 sex. In the smallest specimens of the series before me, the 

 punctuation is finer, and that of the second and third inter- 

 costal space is much more regular than in the typical form. 

 In these also the mental declivity is completely obsolete, being 

 defined only by the transverse row of seta?. Confusa is closely 

 allied to angularis, with which LeConte appears to have 

 confused it. See remarks under angularis. 



92. D. angularis Lee. 



Oblong, elongate, very little wider behind, rufotestaceous, shining, 

 the elytra minutely alutaceous. Mentum flat, rather feebly declivous 

 in anterior fourth, margin of declivity with row of seta? but scarcely 

 at all elevated. Clypeal margin angulate, emarginate at middle, sides 

 sinuate near the angles making the latter quite prominent; clypeal 

 suture straight, distinct though not excavated; front evenly broadly 

 convex, punctuation of head and clypeus dense but not crowded, 

 evenly distributed; distance between the eyes three and one- third 

 times the width of the latter, as seen from the front. Prothorax not 

 quite one-half wider than long, widest a little behind the middle, sides 

 strongly rounded at this point, nearly straight and with just a sus- 

 picion of a sinuation before the angles; front angles a little obtuse; 

 hind angles very obtuse, vertices somewhat rounded; punctuation 

 nearly uniform in size like that of the head, but less dense, the punc- 

 tures separated by from a little less to a little more than their own 

 diameters, scarcely closer laterally. Elytra very nearly three times 

 as long as the prothorax, slightly more than one-half longer than wide; 

 costae rather well defined, first intercostal space three times the width 

 of the sutural interval. Second nearly two-thirds the width of the 

 first; punctures numerous and confused in all the broader intervals, 

 costae slightly more convex, each with a single line of distant fine 

 punctures. Body beneath rather finely not very closely punctured 

 at the sides, metasternum nearly smooth at middle. Teeth of anterior 

 tibia equidistant, the upper one midway between base and apex- 

 Hind thighs rather slender, very sparsely finely punctate at middle.
