270 THE CANADIAN ENTOMOLOGIST. 



at basal third, and one at the middle, a small spot at inner and just 

 before apical third, and an entire but slender apical lunule. Length, £ , 

 n.o mm.; width, 4.2 mm. Arizona (Congress Junction). 



C. triplicate, n. subsp. — Similar to Snowi but more elongate, with 

 the anterior parts stouter, the head very minutely and closely strigilate 

 between the eyes ; prothorax larger, about as wide as the head, more 

 transverse and more strongly obtrapezoidal, the punctures laterally con- 

 fused, though with a single regular series near the margin ; elytra more 

 elongate, two-thirds longer than wide, with fovea?, punctures and minute 

 granulation as in the allied forms, the punctures smaller and closer than in 

 Snowi, feebler and simple, though distinct throughout each elytron, with a 

 pale spot on the humerus, another submarginal and smaller at the middle 

 and at the posterior arcuation, and a slender transverse spot at the apex. 

 Length, <$ , 11.4 mm.; width, 4.2 mm. Colorado (Robinson). 



C. velutoidea, n. subsp. — Rather more olivaceous-green, smoother 

 and more depressed above than in either of the preceding ; head nearly as 

 in triplicans, but with the left mandible more abruptly bent and with its 

 external curve much more narrowly rounded ; prothorax nearly similar 

 and almost as wide as the head ; elytra shorter and relatively broader, 

 one-half longer than wide, the punctures very small, feeble and much 

 sparser, wholly obsolescent apically, each elytron more evidently impressed 

 along the line of fovea? and with a white spot on the humerus, one at outer 

 fourth at the middle and at inner third rather before apical third, and a 

 complete apical lunule. Length, <$ , 10.5 mm.; width, 4.25 mm. A 

 single example from an unrecorded locality, but probably from Colorado. 



In the sexguttata group patruela is well distinguished as a species by 

 its very dense sculpture, duiler, more olivaceous-green colour and com- 

 plete median band of the elytra among other characters. Sexguttata is of 

 a more bluish green and has the elytral punctures smaller and well spaced ; 

 my examples are from North Carolina to northern New York and 

 Indiana; confused with this, but constituting a distinct species, is the 

 following : 



C. Levettei, n. sp. — General form and structure as in sexguttata, the 

 maculation of the elytra similar, except that the inner post-median spot is 

 generally subobsolete, but wiih the coloration of a brighter and purer 

 green, the elytral punctures stronger and more close-set ; distinguished 

 principally, however, by the notably longer legs in both sexes. Length, 

 $ , $ , 1 2.0-14.0 mm.; width, 4.8-5 6 mm. Iowa.
