 Readilv distinguished at sight from our other glabrous species, by the 

 more elongate form of the body. The original specimens came from 

 Fort Whipple, Arizona, but it is now known from several other points 

 in the southern part of that Territory. I have taken it in numbers at 

 light in Phcenix and Nogales, and in still greater abundance at Tucson, 

 where it swarms about the arc-lights by the hundred. During the day 

 I have met with it clinging to the smaller twigs of the " palo verde " 

 on the hills near Tucson. 



C. lanigera Linnaeus, Systema Naturae (Edit. X), 1760, p. 350. 

 This common species occurs from Kansas eastward and exhibits con- 

 siderable variation in size and in punctuation ; the greater measure- 

 ment cited in the table is taken from a specimen secured at Bayfield, 

 Wisconsin, in which the sides of the prothorax are more rapidly and 

 less arcuately narrowed behind than usual. This individual has the 

 sides of the elytra subangulate, with a well marked tubercle in the 

 angulation, like the females of C. flavida. Dr. Harris (Insects Injuri- 

 ous to Vegetation, p. 25) says that C. lanigera attacks the leaves of 

 the pear, elm, hickory, poplar and probably other trees. It is fre- 

 quently attracted to lights. 



A curious variety of this species, with the label Prescott, Arizona, 

 has been loaned me by Mr. Chas Fuchs. While it has all the essen- 

 tial characters of C. lanigera, it is colored in such a manner as to 

 present a totally different appearance. The metallic lustre of the 

 head and thorax is more pronounced, the pronotum broadly brownish 

 at the sides ; the elytra are ornamented by a common brown sutural
