Male {Incomplete form). — Third and fourth ventrals with the plica and fovea as 

 above, the fourth with a very short lobe from its posterior margin (PI. 1. fig. 21). 



Male {Imperfect form). — Third and fourth ventrals with the normal plica and 

 fovea, fourth ventral truncate posteriorly (PI. 1, fig. 22). 



Female. — Third and fourth ventral segments simple; last ventral entire. 

 This species closely resembles hicolor^ and might readily be mistaken 

 for a variety of it. The head is similar in color to the thorax and elytra. 

 In hicolor the meso-metathorax is piceous in all the specimens I have 

 seen, in texanum rufo-testaceous. The punctuation of the elytra, although 

 nearly as coarse, causes the entire surface to appear less irregular than in 

 bicolor. 



Eight specimens, five S three $ , have been examined, they are from 

 southwestern Texas. 



10. C I^econtei (carolinuvi Lee). — Castaneons, shining, head piceous, very 

 sparsely pubescent. Antennse shorter than the head and thorax, rufo-testaceous, 

 third joint slightly longer than the second. Head oval, sides parallel, hind an- 

 gles gradually rounded, surface feebly shining, moderatelj' coarsely and rather 

 closely punctate, front smoother. Thorax narrower than the head, about one- 

 fourth longer than wide, median smooth space well defined, on each side of which 

 the punctures are coarse, deep and closely placed, but distant near the lateral mar- 

 gin. Elytra one-third wider than the thor&x and slightly longer, the punctuation 

 coarse, moderately deep, closely and regularly placed. Abdomen moderately 

 coarsely and sparsely punctured, the punctures finer than on the head. Legs 

 rufo-testaceous. Length ..34-..>S inch ; 8.5-9.5 mm. • 



Male {Complete form).— Third ventral witli moderately long, distinctly elevated 

 setigerous plica at centre; fourth with a moderate fovea at centre, the posterior 

 margin prolonged at middle in a lobe which reaches the middle of the sixth seg- 

 ment, the base broad, the sides convergent, the apex broad and obtuse: seventh 

 ventral ertire (PI. I, fig. 17). 



Male {Incomplete for 711). — Third and fourth ventrals plicate and foveate as above 

 the lobe of the fourth very short, barely reaching the middle of the fifth segment 

 (PI. 1, fig. 18). 



Male {Imperfect form). — Third and fourth ventrals with normal plica and fovea, 

 the fourth ventral truncate posteriorly without trace of lobe (PI. 1, fig. 19). 



Female. — Ventral segments absolutely simple without trace of plica or fovea. 



Although this species is placed in the series following bicolor, resem- 

 bles hadium, although more slender and smaller. The males ^re also 

 difficult to distinguish except by comparison, those of the present species 

 will be observed to have the thorax more numerously punctured, the 

 punctures of the elytra less coarse, closer and more regular. The color 

 of the abdomen will readily distinguish it from either hicolor or texanvm. 



This species has been determined by Dr. LeConte to be caroUnum 

 Erichs., but I think incorrectly. 



Occurs in southwestern Texas and Kansas.
