qo [February, 



smooth claw of Sitaris, triple but not three- jointed in S. colletis and in 

 Trmngulinns (a general name for Meloe larvae). The jaws do not 

 seem modified for holding purposes, but have an extremely acute point, 

 no doubt for piercing the tough skin of the wasp-grub. It appears to 

 possess suckers for holding at the posterior extremity ; they belong to 

 the tenth abdominal segment, there being no trace of the curious dorsal 

 organ of Sitaris.

ON SOME IMPOSSIBLE SPECIFIC NAMES IN MICRO-LEPIDOPTERA. 

 BY EDWARD MEYRICK, B.A., F.R.S. 



In a paper published in the Transactions of the American Ento- 

 mological Society, Vol. xxxiii, 1907, by Mr. W. D. Kearfott, on new 

 species of Tortricina, are a number of specific names which are openly 

 and obviovisly based on a barbarous and unmeaning gibberish, and in 

 my opinion must be rejected as null and void. They are given below, 

 and carry their condenmation on their face. If a name is without 

 meaning and only consists of a chance ai'rangement of letters, memory, 

 deprived of the clue afforded by sense, is unable to recall the name 

 with accru'acy, since the letters might just as well have been arranged 

 otherwise ; hence on every occasion reference would have to be made
