this respect, but they are stronger in subtomentosa. The clypeus is 

 somewhat as in the kerni group but lacks the cusp-like sinus of the 

 apex, the apical margin being in fact almost perfectly even and 

 devoid of any kind of sinus; it also differs in having the teeth of the 

 anterior tibiae more approximate among themselves and in having 

 spots or uneven lines of tomentum on the elytra, these being much 

 more conspicuously developed than in the fulgida group. The 

 hind tarsi are rather short but not thick and pubescence above, 

 beneath and on the legs, is much more developed than in any of 

 the preceding groups. The base of the pronotum has a very 

 shallow and generally not very sharply defined sinus at the scutel- 

 lum. The typical form is not now at hand, the only two species 

 in my collection being the following: 



Body elongate-oval, rather convex, shining, piceous-black and with rather 

 long coarse yellowish pubescence above, close on the pronotum, 

 sparse on the elytra; under surface and legs shining, black, the ab- 

 domen picescent, the sterna, sides of the abdomen and legs with long 

 coarse conspicuous hairs; front densely, the clypeus more feebly and 

 rugulosely punctate, the former conspicuously pubescent; clypeus 

 abruptly though moderately reflexed and broadly rounded at apex, 

 the sides not elevated; prothorax a fourth wider than long, trape- 

 zoidal, the sides a little more arcuate just before the middle; punc- 

 tures strong, deep, close-set and very even throughout, the median 

 line not modified in any way; scutellum with numerous moderate 

 punctures bearing coarse hairs, smooth along the middle; elytra a 

 third longer than wide, not distinctly narrowed posteriorly, the 

 punctures numerous but not dense, shallow, elliptic-annular, open 

 behind, becoming not closer but rather more transversely lineiform 

 laterally, confused throughout between the costae and on the broad 

 sutural interval, the costae low, shining and impunctate; tomentose 

 areas numerous, still more so laterally and solid at apex, generally 

 very irregular in shape though more or less lineiform; pygidium 

 convex, subumbonate, almost wholly tomentose, except along the 

 apex, the incised irregular lines well separated. Length (cf) 10.5 

 mm.; width 6. 4 mm. Arizona (Huachuca Mts.). [Euphoria sonorce 

 Bates] histrionica Thorns. 



Form more elongate and less oval, shining, except in the tomentose areas 

 of the elytra, which are very different from those of histrionica, being 

 less comminuted, more rounded, numerous on the flanks, solid at 

 apex and tending also to form a transverse series across the elytra 

 at about the middle; color black, the elytra castaneous, the abdomen 

 more or less rufescent; pubescence not quite so long as in the pre- 

 ceding but similar otherwise; head nearly similar but with the clypeal 

 apex not evidently reflexed; prothorax also similar but rather shorter, 

 the punctures not quite so close-set; basal sinus very shallow and not
