Dr. Uhler reports this species from Texas and New Mexico, Prof. 

 Cockerell from Colorado, and Prof. Osborn has an example taken 

 at Tuscan, Arizona, by H. F. Wickham. It is included in Prof 

 Smith's List of the Insects of New Jersey, but I strongly suspect 

 that this is an error of determination. Possibly the closely related 

 Mineus strigipes was the insect intended. 



Perillus exapf ii!>» Say. 



In this pretty and variable species the spine on the inner face of 

 the anterior femora is reduced to a mere tubercle. The whole upper 

 surface is closely and deeply punctured. The antennfe are black, 

 with the incisures and sometimes the base of the first joint pale, and 

 the head is strongly deflexed. Of this species 1 have before me the 

 following varieties : 



Var. a, variegatus Kirby. — Color yellowish fulvous, marked with 

 black as follows: head, excepting the narrow fore borders and 

 sutures beneath ; pronotum, excepting a broad transverse band an- 

 teriorly ; scutellum, excepting a broad submarginal vitta ; elytra 

 within ; some large spots on the breast and venter, and the legs in 

 part. Colorado and Montana. In July of this year I took an ex- 

 ample of this pattern at Fort Collins, Colorado, in which the color 

 on the pronotum is deepened to crimson, and Dr. E. P. Felt has 

 sent me one taken at New Russia, New York, in which the pale 

 color over the whole insect is of a rich crimson red. In all of these 

 there is a narrow black border on the base of the pronotum before 

 the scutellum. Zicrona marginella Dallas is a red form of this 

 variety. 



Var. b. — Pale whitish yellow. Head crimson red with the base, 

 tykis and slender outer margins black. Pronotum with a transverse 

 band before that is deflected and runs parallel to the outer margins 

 almost to the humeri, and an arcuated band on the hind margin 

 before the base of the scutellum black ; between these black bands 

 is a broad arcuated crimson band connecting the humeri and slen- 

 derly edged with the pale ground color. Scutellum with a median 

 longitudinal vitta, abbreviated at either end, and the narrow lateral 

 margins almost to the tip black ; at either side at base is an oblique
