Cakecea, — -This and the foui' succeediug genera have all been 

 included by Meigen, Macquart, Scbincr, and others, in the genus 

 Ccenosia ; but they dii^er from each other, as I have pointed out in 

 the analytical table, by the relative size of the alulets, as well as by 

 the state of the arista. These genera, upon which I shall not further 

 dilate, include a considerable number of small flies, many of them 

 found by sweeping among grass and herbage. They are of various 

 shapes and colours, and only agree in having the eyes distant in both 

 sexes. Their bodies are mostly spotted. The number of doreal bristles 

 varies considerably in the different species ; thus there is only one in 

 front of the suture, and three behind it, in Caricea tigrina and Ccenosia 

 sexnotata ; while in Caricea ciJiacosta and Ccenosia niqripes there are 

 two in front and four behind : again, other species, as Ccenosia meditata, 

 have two in front and three behind ; while, therefore, these dorsal 

 bristles are very valuable specific characters, they are here of no use 

 in a generic sense. 



In concluding these few remarks upon the Anihomi/iidce, I beg to 

 say that I shall be much obliged to any entomologist who will forward 

 any specimens of this family for my inspection, and I Avill undertake 

 to return them named as accurately as is in my power.

ON ASPEONDYLIA ULICIS, TRAILL. 

 BT G. H. VEEEALL. 



In the number of the Scottish Naturalist for October, 1873, Mr, 

 J. W. H. Traill describes a gall found on JJJex europceus on Scotston 

 Moor, near Aberdeen, and slightly describes the perfect insect, which 

 he names Asplwndylia ulicis. Thinking a more detailed description 

 advisable, in order to confirm Mr. Traill's name, I wrote to Mr. W. A. 

 Vice asking for specimens, and he sent me two long ago ; but, owing 

 to their ha\ ing fared badly in travelling, I did not attempt to de- 

 scribe them. Last August, I was collecting in company with Mr. 

 J. Scott between Poole and Bournemouth, and when glancing over a few 

 Diptera he had in his collecting bottle, I remarked that one resembled 

 the AspJiondi/Jia sent by Mr. A^icc, and, looking at the first piece of 

 furze by my side, I noticed the galls in abundance. Upon my return 

 home, I found that when I visited Bournemouth in July, 1871, I had 

 caught half-a-dozen of the insect, having, no doubt, been attracted by 

 its large size for a Cecidomyia. With the help of these, I therefore 

 give a short description.
