Occurs in Arizona, in New Mexico (Santa Fe, Albuquerque, Pecos), 

 and in Wyoming. 



Trichodes bibalteatus LeConte. 



Trickodes bibalteatus Lee., Jour. Acad. Nat. Sci. Phil., iv, 1858, 

 ser. 2, p. 18; Horn, Trans. Amer. Ent. Soc., v, 1876, p. 231, 

 pi. i, fig. 27. 



Moderately robust, feebly shining; head, thorax, and base of 

 elytra clothed with moderately long, reddish yellow pilosity. Head 

 dull red, varying to pitchy black, very densely but not very coarsely 

 punctate, as is also the thorax; palpi pale; antennae varying from 

 pale testaceous to obscurely red, the club from brownish red to black. 

 Thorax dull red, the basal portion often more or less pitchy black; 

 slightly longer than broad, broadest behind the middle; sides very 

 slightly arcuate, feebly compressed at' apical fourth. Scutellum 

 black. Elytra orange-red to pale yellow, with two rather broad fas- 

 ciae, one just before the middle and the other midway between the 

 middle and the apex, black; the fasciae clothed with very short, dense 

 black pubescence; surface rather sparsely coarsely, cribrate-punctate ; 

 apex immaculate. Body beneath, legs and abdomen, shining, black, 

 frequently with a purplish, bluish or greenish tinge; the apical seg- 

 ments of the abdomen often red, the tarsi sometimes paler. Length 

 10 16 millim. (Elytral markings, pi. VI, fig. 25.) 



Slightly resembles both simulator and apivorus, from both of which 

 it may be known by the apices of the elytra being never blue or black 

 but always reddish or yellow. The pilosity of the head and thorax 

 is much shorter, the apices of elytra are always rounded and the 

 thorax is more finely punctate than in simulator; from apivorus it 

 differs in having the club of antennae shorter, punctuation of elytra 

 less dense, the pilosity of the head and thorax paler, and the thorax 

 to a more or less extent reddish. The color of the elytral fasciae is 

 black, in apivorus purplish or blue black. 



Most of the specimens in collections are labeled "Texas," which 

 was the locality given by LeConte in the original description. Prof. 

 Wickham has taken bibalteatus at Winslow, Arizona, and also at 

 Alpine, Texas (4,400-6,000 ft. el.). A specimen from the last locality 

 has the orange-red of elytra, a much stronger shade than in any other 

 example the author has seen.
