Head red, rather sparsely punctate, below with a black median 

 spot, palpi black; antennae black, first joint below and the two 

 following often more or less reddish. Prothorax red with a black 

 median vitta extending along apex and base; surface sparsely punc- 

 tate. Elytra rather densely and coarsely punctate, intervals between 

 the punctures more or less rugose; median fascia in form of a trans- 

 versely oval spot; sutural vitta above the median fascia, narrow, 

 either parallel or narrowing obliquely to the scutellum, scarcely attain- 

 ing the base; dark humeral spot absent. Body beneath and legs black, 

 last ventral segment red, penultimate segment red at sides and black 

 at middle; ventral segments rather sparsely punctate. Claws simple 

 in both sexes. Fifth ventral segment of male feebly emarginate, last 

 dorsal segment sub truncate at apex in the male and broadly rounded 

 in the female; length 8.5-13.5 mm. Alpine, Texas (Wickham); 

 Mexico (Duges). 



I have seen about eighteen specimens of this species from Texas 

 and Mexico, and though the markings are variable, they are less so 

 than in most of the other species. 



Generally a species of medium size: the largest measurements above 

 were taken from a Mexican specimen in the collection of the United 

 States National Museum. It is an eashV recognizable species. 



AULICUS EEMORALIS Schaeffer. 



Aulicus femoralis Schaeffer, Journ. N. Y. Ent. Soc, vol. 25, 1917, p. 132. 



Head red, coarsely and closely punctate; palpi black or piceous 

 rarely reddish; the outer joints of antennae black or piceous, but the 

 club of the male often pale. Prothorax black at middle, apex and 

 base, red at sides; surface moderately punctate, punctures rather 

 coarse. Elytra closely and coarsely punctate, intervals between the 

 punctures rugose; basal part of sutural vitta broad, as wide or wider 

 than the red humeral space, sometimes gradually widening towards 

 base; median vitta more or less constricted at middle and wider 

 laterally and in heavily marked specimens nearly uniting laterally 

 with the apical blue spot; black humeral spot sometimes absent. 

 Underside and all the femora largely red, except apex of the latter 

 and tibiae and tarsi black; fifth ventral segment occasionally more or 

 less blackish and in the male rather deeply arcuate-emarginate at 

 apex, in the female truncate. Last dorsal segment at apex emargi- 

 nate at middle in the male, broadly rounded in the female. The 

 inner claw of anterior tarsi of the male distinctly dentate, of the
