Fig. 47. Wing of Microphorus hiemalis. 



Fniuih'. Face and front pale gi^ey. Proboscis a littlei 

 shorter than the height of head. Palpi ver}'- short, lessi 

 than one-foui"th the length of the proboscis. Antennae — ■ 

 without the style — about half the length of head, the first 

 two joints very small, the third with a. broad base and 

 pointed apex, terminated by a long aristiform style, which 

 is a little longer than the three joints together. Front 

 with ocellar and vertical bristles. Thorax pale brown, 

 with two narrow, dark brown stripes, bearing long dorsal 

 and lateral bristles ; scutellum with two black, erect, mar- 

 ginal bristles. Abdomen brown ; ovipositor brownish-yel- 

 low. Legs entirely light brown, without any distinct 

 bristles. Wings hyaline, with a brownish tinge, without 

 any trace of a stigma; halteres j^ellowish-white. 



This species bears some resemblance to the species of 

 Rhampliomina already described, but may be distinguished 

 by the long aristiform style. It is a winter species, frer 

 quenting low vegetation during the month of July.

 short, hardh^ extending beyond the oral aperature. Eyes 

 joined in both sexes, though sometimes only touching 

 below the antennae. Antennze a little longer than th© 

 head, the first and second joints of almost equal length, 

 the third about twice the length of the first two together, 

 and terminated by a long arista, which varies in length 

 from that of the third joint to one-and-a-half times the 

 length of the three joints together. Thorax much arched, 

 usually bearing acrostichal and dorsocentral bristles, also 

 a notopleural, a postalar, and, more rarely, a supraalar 

 bristle; scutellum with two or more marginal bristles. 

 Abdomen slender. Legs either nearly bare, or distinctly
