ANNOTATED LIST OF BRITISH ANTHOMYIID&. 

 BY R. H. MEADE. 



{continued from page 205.) 



13. PIEZUKA, Eond. 



Gen. eh. — Head smooth and semi-circular ; eyes large, bare, and 

 sub-contiguous in the male ; antennae long, the third joint about three 

 times the length of the second ; arista plumose ; alulets of moderate 

 size, with unequal scales ; abdomen depressed, with five distinct seg- 

 ments ; wings with the veins as in the genus Homaloniyia ; legs 

 simple. 



P. pardalika, Eond. 



This genus contains, as yet, only one recorded species, which bears 

 a strong general resemblance in form and structure to those in the 

 genus Homalomyia, but differs by having the arista plumose, and the 

 abdomen with five segments, four only being distinct in the Homa- 

 lomyice. 



P. pardalina is of a pale yellowish colour, the face is silvery- white ; the eyes 

 in the male are bordered, and separated above, by a double white stripe, which ex- 

 tends to the vertex, where a small elongated triangular black spot is interposed, 

 upon which the ocelli are placed ; the antenna? are yellow, with the third joint grey, 

 the colour becoming darker towards the end ; the thorax is pale slate-grey, and has 

 a wide central longitudinal dark stripe, with two lateral, somewhat semi-lunar, lon- 

 gitudinal spots, one over the base of each wing ; the shoulders are yellow ; the 

 8cutellum is grey at the base, but yellow at the apex ; the abdomen is yellow, with 

 a more or less distinct, narrow, interrupted, black dorsal stripe on the last three 

 segments, and a black mark on the margins of the third and fourth segments ; the 

 sub-anal male appendages are large, globular, and of a yellow colour ; the legs are 

 entirely yellow, with the exception of the tarsi, which are black. Long. $ , 6 mill.* 



I have not seen a female, but Rondani says that it is very similar to the male. 



This peculiar species appears to be rare on the continent of Europe, as well as 

 in England. I am not aware that its occurrence has been recorded auywhere except 

 in Italy. I have seen two British specimens ; one was captured by myself near 

 Bicester, in Oxfordshire, and the other was found by Mr. C. W. Dale near Oxford. 



14. AZELIA, E. Desv. 



Atomogaster, Macq. 

 Anthomyia, p. Meig., Schin. 

 Aricia, p. Zett. 

 Gen. ch. — Head round ; eyes very large, bare, contiguous in the 



* I gladly accept the suggestion made by Mr. McLachlan in the last number of tbis Magazine, 

 and for the future will use millimetres instead of lines in the measurement of Diptera.
