■Well distinguished amongst the Ilopatra by its rather largely- 

 developed and equally-rounded prothorax (which, together with the 

 head, is closely and coarsely subpunctate-granulate) , by its nearly 

 bald surface, and by its elytra (which are a little narrower anteriorly 

 than the prothorax, and have their humeral angles acute and prominent) 

 being less densely sprinkled with much smaller granules, and with 

 their alternate interstices obtusely and obsoletely raised. I have had 

 much pleasure in retaining for it the name proposed by Mr. Blackmore, 

 who is desirous to place on record the obligations of entomologists to 

 Dr. Hooker for the interesting Coleoptera brought by him from the 

 hitherto unexplored regions of the Atlas. T. V. W. 



ON THE AEEANaEMENT OP THE BRITISH ANTHOMYIIDJE. 



BY R. n. MEADE. 

 (concluded from page 203.) 



Mtdjia. — I have placed in this genus a number of species mostly 

 of considerable size and oval form, which differ from those in the 

 genus Syetodesia by having naked eyes, and from those in Spilogaster 

 by having unspotted bodies. Macquart placed them in the second 

 division of his genus Aricia ; and Schiner and Rondani have included 

 them in Spilogaster ; they appear, however, to form a more natural 

 group than many others that have been raised to the rank of genera. 

 I have adopted the name of Mi/dcen, as it had been applied by Dcsvoidy 

 to M. pagana and to one or two others of the leading species in the 

 genus. 



In this and the two preceding genera two thoracic bristles are 

 placed in front of the transverse suture, in a line with four behind it, 

 in all the British species I have examined, with the exception of Uij- 

 etodesia leeta, which has only three behind the suture. 



Spilogasteh. — This genus, as its name implies, is characterised 

 by the species having the body spotted ; four, or sometimes six, dis- 

 tinct and often triangular spots being arranged in pairs (one on each 

 side of the median line) on the dorsum of the second, third, and some-
