THE ENTOMOLOGIST. 



The specimens sent me by Dr. Thomas were obviously (and 

 at a glance) our " Forest Fly," the special pest of the New 

 Forest, of which I saw only too many in the year 1895, when 

 the circumstance of the autumn manoeuvres being in that district 

 brought the habits of the pest under special observation ; and 

 careful comparison, both with descriptions and types, showed 

 these specimens, now sent by Dr. Thomas, to be Hippobosca 

 equina, Linn. 



Thus, in addition to the English head-quarters of the species 

 in the New Forest in Hampshire, we have the subordinate 

 localities of the valley between Portmadoc and Beddgelert in 

 North Wales, from which I received specimens in 1895, taken 

 by the driver of one of the coaches off one of the horses going to 

 and fro between the above localities ; also the Ystalyfera locality, 

 from which specimens have now been sent. And as Dr. Thomas 

 mentions having "generally" found this fly (of which he now 

 sends samples from Ystalyfera) in the parish of Ystradgynlais 

 in Breconshire, this might, I think, be fairly considered as yet 

 another locality.

A NEW SPECIES OP CHARAXES. 

 By Percy I. Lathy. 



Charaxes gamma, sp. nov. 



$ . Fore wings blackish brown. Just beyond cell crossed by a 

 series of five pale yellow spots, the first being just above first median 

 nervule, the second minute and nearer hind margin, between first and 

 second median nervules ; the remaining three larger, the third being 

 between second and third median nervules ; and the fourth and fifth, 

 which adjoin, between the third median nervule and submedian nervure. 

 Beyond this series, and in the same position to the nervules, are five 

 more pale yellow spots, arranged in a straight line, all of which but the 

 second are smaller ; above and on each side of the upper spot of this 

 series are two pale yellow spots, so placed that they form, with the 

 five, a Y ; the lower of the two spots forming the branch of Y next 

 hind margin minute ; hind margin faiutly yellowish between ner- 

 vules. Hind wings blackish brown ; a pale yellow band across the 

 middle, extending from costa to first median nervule. A series of 

 submarginal pale yellow markings, of which the upper are large and 

 round, the two next anal angle being mere lines ; within these sub- 

 marginal markings three dull greenish yellow lunules, situated 

 respectively between first and second and second and third median 

 nervules, and third median nervule and submedian nervure ; hind 

 margin faintly yellowish between nervules. Antennae black, end of 

 club orange-brown. Under side : Fore wings silvery ; a conspicuous
