Daggett, the elytra are much darker than in the writer's specimens 

 from San Bernardino Ranch, Cochise County, Arizona, the reddish 

 brown portions being greatly reduced in extent, the legs are bluish 

 black, the femora having a more conspicuous bluish tint, the knees 

 are just touched with ferruginous, tibiae at base dark, but becoming 

 gradually ferruginous towards the apices, the tarsi ferruginous. In 

 all the author's specimens the antennae are entirely red, thus differing 

 from the type which has the last three joints black. Length 13-15.5 

 millim. (Elytral markings, pi. VI, fig 23.) 

 Known only from southern Arizona.

Rather robust, dark blue; head and scutellum with purplish or 

 greenish tint; elytra varying from yellow to orange-red, with two fas- 

 ciae and apex blue to bluish black. Head, thorax, and elytra at base 

 clothed with very long yellowish pubescence. Antennae obscurely 

 reddish, club blue black. Head densely punctate. Prothorax dark 

 blue, coarsely and very densely punctate, punctures confluent. 

 Elytra clothed with pale yellowish pubescence, short except at base; 

 coarsely, densely and deeply punctate, substriate; apices (c?) trun- 

 cate, the sutural angle slightly prolonged in a sharp spine; at about 

 basal fourth a rather broad, slightly undulate fascia; behind the 

 middle a much broader fascia and the apex broadly blue to blue black. 

 Body beneath and abdomen dark blue. Legs a lighter more brilliant 

 blue, and with the venter, clothed with long yellowish hairs. Length 

 13-15 millim. (Elytral markings, pi. VI, fig. 24.) 



The markings in this species are quite similar to those of apivorus, 

 from which it may be distinguished by the form of the antennal club 

 which is here very short, being only about one-half longer than the 

 width of the apical joint, the thorax is more coarsely (nearly crib- 

 rately) punctate, and the elytral apices of the male are truncate. 

 The punctuation of the elytra is more dense and confluent than in 

 bibalteatus, apivorus, or illustris, and its allies. 



The so-called variety, flavescens Ckll., is placed as a synonym, as 

 it seems unwise to retain a variety founded on a slight variation in 

 the color of the elytra, especially in genera where the species are known 

 to vary so greatly in this respect as they do in the genus Trichodes.
