from Coronado, San Diego, Santa Barbara, and Los Angeles Countj'^, 

 California. So far as these localities go, the insect seems to belong 

 rather to the transition zone of the Rocky and Sierra and Ne\ada 

 mountains, and to the more arid portions thereof. 



Nothing of the habits of this insect appears to be known and it is 

 not a very conmion species. 



There are three male and two female sj)ecimens of a hhidkChloiloii 

 {J'ifl/N()(hfi) in the collection of the American Entomological Society 

 in Fhiladelpliia, which I am unable to distinguish from this species in 

 any way oxce})t l)y size, the males being oidy 12 mm. and the females 

 15 and 16 nun., respectivel}^ in length. The}" were taken in Colorado 

 and " W. T." Whether they are the same or a different species, I 

 must leave for others to determine.

Ti/pe. — "One male found on sumach Howers in August. (Coll. (x. 

 W. Belfrage.)" This t3"pe is now in the National Museum at Wash- 

 ington. A specimen labeled in Cresson's handwriting is in the collec- 

 tion of the American Entomological Society at Philadelphia. 



Female type (now tirst described) in t\w collection of the Massa- 

 chusetts Agricultural College at Amherst, Massachusetts. 



The following description was prepared from the tj'pe specimen. 



Black, except the tirst two segments ])ehind the petiole, and a small 

 portion of the third, which are pale ferruginous; wings uniformly 

 fuliginous; without pubescence; hairs everywhere black. 



Male. — Head: rather broad; frons somewhat hollowed ])etwoen the 

 eyes; clvpeus quite flat, very closely, minutely punctured and with 

 numerous coarser punctures and long iiairs; its anterior edge with a 

 very slightly reflexed, smooth, narrow rim; frons closely, very min- 

 utely punctured, and also quite closely covered with coarser punctures, 

 which are not as coarse as those of the clvpeus; with numerous black 

 hairs; frontal suture distinct and continuing behind the median ocellus 

 to a transverse, backwardly-arched groove behind the lateral ocelli; 

 this with two obli(iue grooves inclose the ocelli in a triangle; vertex, 

 occiput, and cheeks with tine punctures and coarser ones, al)out like 

 those of the frons, but becoming coarser on the lower part of the 

 cheeks; hairs corresponding in size and abundance to the punctures; 

 longest low down on the cheeks; inner margins of eyes converging 

 toward the clypeus; cheeks at their widest part about half the width 

 of the eye as seen from the side; antenna^; scape and pedicel glisten- 

 ing black, with a few short hairs, particularly toward the end of the 

 scape, and a few ver}- tine hairs on the pedicel; tirst iilament segment
