THE CANADIAN ENTOMOLOGIST. 237 



or impressed; middle tibise sinuate within and mucronate at tips, hind tibiae 

 straight ; apical ventral segment broadly arcuately emarginate. One of 

 the above exarnples has been in my collection many years, and was once 

 submitted to Dr. Horn, who referred it doubtfully to debilis. It is, 

 however, abundantly distinct from the latter by the dense punctuation of 

 the entire upper surface, deeper clypeal emargination, brilliant colour of 

 head and anterior margin of pronotum, form of prothorax, and other 

 details. The front tibiae of the $ in debilis are not emarginate above the 

 dilatation. 



Chrysobothris microfiiorpha, n. sp. — Elongate, not depressed, dark 

 brown bronzed with traces of violaceous lustre on the anterior part of the 

 pronotum and on parts of the elytra; front green ( ^ ), vertex and occiput 

 bright coppery-red; beneath piceous, faintly bronzed, tips of middle thighs 

 and apical half or more of hind thighs brilliant coppery-red. Antennae 

 piceous, becoming bronzed at base, third joint much shorter than the next 

 two united ; outer joints gradually narrower. Front moderately convex, 

 with conspicuous though not very dense white pubescence ; punctuation 

 moderately close and a little irregular, having a small smoother area each 

 side of the median line, above which is a well-defined vertical chevron ; 

 clypeus broadly arcuately emarginate, sides subtruncate. Prothorax 

 slightly less than twice as wide as long, sides subangulate at 2/5 from 

 base, before which they are nearly straight and parallel, posteriorly straight 

 and strongly convergent to base, which is narrower than the apex, and 

 about 3/5 as wide as the base of the elytra ; surface uniformly convex, 

 without distinct impressions ; punctures uniformly distributed, distant by 

 rather more than their own diameter, and without tendency toward 

 strigosity except very feebly near the hind angles. Elytra ^ wider than 

 the prothorax, sides parallel and straight to about apical third, apex 

 serrulate, surface without distinct fovese e^jcept ihe basal ones ; the inner 

 costa feeble but evident toward the apex ; punctuation similar to that of 

 the pronotum. Prosternum rather strongly lobed in front, closely 

 punctate anteriorly, a little less so posteriorly. Abdomen moderately 

 punctate and pubescent, without lateral callosities. Length, 4^ mm. 



Arizona. As in the preceding species, two examples are at hand, 

 one without definite locality, the other taken at Hot Springs by Barber 

 and Schwarz. 



Both specimens are ^ 's, and have the front tibiae slightly arcuate and 

 dilated within at apex, middle tibiae less arcuate, hind tibiae straight ; last
