855 Species. 



The Nemocera have therefore been increased by three-and- 

 a-half times the number of species known less than ten years 

 ago. 1 Descriptions of those included in the above table as 

 known, but not yet actually published, will appear during the 

 next few months at latest. 



Turning to the next Suborder, the Brachycera (I prefer to 

 retain, for the present, the older system of classification), the 

 differences are not so marked, but only because many of the 

 groups have not been dealt with, and not so assiduousty col- 

 lected ; for those that have been worked out afford a high per- 

 centage of new forms* 



Stratiornyidce. — This family was revised to the best of my 

 ability 2 recently, only six new species being added. 



Tabanidce. — Miss Ricardo has recently worked through 

 the British Museum and Indian Museum collections in this 

 group, and has forwarded a voluminous manuscript on Tabanus, 

 which almost brings up to date our knowledge of that genus ; 

 a second paper on the remainder of the family being in 



preparation. 8 



Leptidce and Bombylidce. — Both were revised by me re- 

 cently, 4 and although a certain number of species were un 

 avoidably unrecognisable through the brevity of the older des- 

 criptions, the absence of specimens of many of them, and the 

 impossibility of examining the actual types, I believe that I 

 have allocated the majority of those species originally placed 

 in Anthrax and Exoprosopa to their correct genera; the kind 

 assistance rendered me by Mr. E. E. Austen in this matter by 

 an examination of the types that are in the British Museum, 

 having been most valuable. In my three papers on the two 

 families are added 47 new species.
