96 GEO. H. HORN, M. D. 



tioned is moderately, densely puuctate ; body beneath shining, sparsely punctate 

 with large elongate punctures, the ventral segments with a large lateral callosity ; 

 prosternum distinctly lobed in front; anterior femur with an acute tooth serru- 

 late on its outer edge ; margin of last ventral segment serrulate. Length .36 - .50 

 inch; 9-12.5 mm. (Fig. 125.) 



ilfaZe.— Prosternum tlat, densely punctured and pul)escent; anterior tibia (129j 

 slightly arcuate and with a feeble dilatation at apical fourth ; middle tibia arcu- 

 ate, thicker at tip; posterior straight; last ventral segment (127) semi-circularly 

 emarginate; last dorsal sparsely punctate, triangularly emarginate. 



Female. — Prosternum convex, and smoother at middle, at sides coarsely punc- 

 tured; tibiae nearly .straight; last ventral segment (128) broadlv emarginate- 

 truncate, carinate at basal half of the median line; last dorsal coarsely closely 

 punctate and entire. 



The elytral sculpture is actually that of the frinervia series with 

 the confluence of the costae more sharply defined and limited. In 

 a series of about twenty specimens there is very little variation. 



Occurs in Arizona. 



26. C. texana Lee. — Form rather elongate with the general habitus of den- 

 tipes, but more convex, cupreo-seneous, the thorax usually more cupreous ; an- 

 tennae gradually more slender to tip, greenish % , cupreous 9 , the third joint as 

 long as the next two ; front rather less convex, slightly greenish, more densely 

 punctured and slightly pubescent % , more coarsely punctured 9 two feeble cal- 

 losities in both sexes; clypeus (131) feebly but broadly emarginate at middle, 

 arcuate each side ; thorax nearly twice as wide as long, narrowed at apex and 

 base, widest one-third from apex, the sides at middle feebly sinuate ; disc moder- 

 ately convex, the median sulcus very feeble or wanting, on each side near the 

 front a slight callosity, external to which is a depression, the surface sparsely 

 punctate near the middle, densely and coarsely punctate at the sides; elytra a 

 little wider than the thorax, gradually narrowing to apex, almost from the 

 humeri, the sides feebly serrulate, the apices obtuse ; the subsutural costa ele- 

 vated at apex, depressed and forming a broad smooth space near the base, the 

 second costa broadly interrupted and forming broad, smooth spaces, the third dis- 

 tinct at the middle of its extent, the surface rather coarsely and closely punctate, 

 densely near the sides, the basal and humeral depressions moderately deep ; body 

 beneath rather coarsely punctured, rather densely at the sides, ventral segments 

 with distinct callosities ; prosternum with a well marked lobe in front ; anterior 

 femora with a moderate tooth, sinuous and serrulate on its distal margin ; last 

 ventral segment with a serrulate margin and a slightly elevated submarginal 

 ridge. Length .34- .48 inch ; 8.5 - 12 mm. (Fig. 130.) 



i(f«?e.— Prosternum moderately, densely punctate, especially in front, and with 

 a smooth median space ; anterior tibia 134) distinctly arcuate, sinuate on its inner 

 edge one-third from apex, below which is a dilatation which narrows again at the 

 tip; middle til)ia slightly arcuate, the posterior straight; last ventral (132i deeply 

 semi-circularly emarginate, the last dorsal coarsely punctate and at apex feebly 

 notched. 



Female. - Prosternum coarsely and sparsely punctate, a smooth median space ; 

 anterior tibiae slightly arcuate, the middle and posterior straight ; last ventral 

 (133) slightly truncate at tip ; last dorsal coarsely punctate and entire.
