90 [April, 



feature is the dilatation of the encle of the palpi, ■which are thick and clavate. The 

 thorax and legs are black ; the abdomen is rufous, with a wide sinuous (sometimes 

 interrupted) dorsal black stripe, which is dilated, and covers the end of the last 

 segment. The antennae are black and rather short, the last joint being about two- 

 thirds of the length of the second. This is also rare. 



E. LURIDA, F. 



In this and the following species the whole body is clothed with soft hairs, in 

 addition to spines and bristles ; the frontalia are also furnished with numerous soft 

 liairs besides the ordinary bristles, which are weaker than usual, and very irregularly 

 arranged ; the hairs also extend down to the cheeks. In E. lurida the clothing on 

 the abdomen is bright golden-yellow, beneath which the skin is black and shining ; 

 the sides of the abdomen are more or less widely marked with red. The antennae 

 have the first two joints piceous or testaceous, and the third (which is very little 

 shorter than the second) black. The legs are testaceous, the femora being more or 

 less nigrescent. This species is not common. I received one some years ago from 

 Mr. Dale, captured, I believe, iti Dorsetshire ; it has been bred from the pupa; of 

 CaculUa verbaxci. 



E. URSINA, MgU. 



This is larger than the former, being 6 lines (about 12 mm.) in length. It re- 

 sembles U. lurida in general charactei's, but differs by having the abdomen almost 

 entirely black, it being only slightly testaceous on the sides of the basal segments ; 

 the hairs on the abdomen are also less yellow, but whitish, and mixed with black ; 

 the cheeks have also more black hairs upon them than in E. lurida, in which they 

 are mostly pale yellow, though mixed with black bristles ; the anteimte also have the 

 second joint rather longer than in E. lurida. This species is rare. 



2.— MICROPALPUS, Mcq. 

 Oeji. ch. — Body obloug ; eyes hairy ; antennae drooping, with the 

 second joint narrow, elongated, and generally only a little shorter than 

 the third, which is widened and truncated at the end ; arista with the 

 second joint more or less elongated, but always four or five times 

 shorter than the third ; proboscis rather long and projecting, dilated 

 at the end ; palpi very small and short (quite rudimentary), and ter- 

 minating in a little bristle ; wings with a cubital appendix. The 

 female has the frontalia wider than in the male, and armed with a 

 double row of fronto-orbital bristles,* and also has the fore tarsal 

 joints dilated as in the genus Echtnoynyia. The flies in this genus 

 resemble those in the former one in their general habit, but are 

 smaller and feebler in organization.

• As these bristles are usually in a single row in the male, and in a double vow in the female, 

 I shall only mention them again when they depart from this rule.
