214 PCEOILOSOMA FLETOHBEI. 



marked with dirty-white splashes between the white segmental marks. 

 Legs covered with a grey pile ; coxae and trochanters black ; femora 

 obscure luteous, lined with black above and beneath ; tibiae white at the 

 base, the apex sordid luteous, splashed with black ; tarsi fuscous, paler 

 at the base; claws bifid. Wings hyaline ; costa at the base pale testa- 

 ceous; apex and stigma sordid luteous. The tr. radial nervure is 

 received a fourth of the length of the cellule from the apex ; the first 

 tr. cubital nervure is absent ; the second (first)^ cellule is 'a little 

 longer than the third (second), narrow, and having a horny point at its 

 apex ; the third (second) is much broader, double the breadth of the 

 base at the apex ; the apical cellule is shorter than the preceding. 



The $ has the femora and tibiae obscure luteoue, according to 

 Thomson. 



Length nearly 3? lines. 



Of similar form to pulveratum, but smaller ; there 

 are only three cubital cellules ; the second (the third in 

 pulvemtum) is shorter and much broader; the coxae 

 and trochanters are quite black ; the body is more 

 densely pilose, the white marks on the abdomen, too, 

 are broader than those on the sides, being very con- 

 spicuous, while they are not found in pulveratum. 

 From Oandidatum it is known by its more pilose body, 

 the eyes not having a white border, and otherwise is 

 easily known by the structure of the posterior wings. 



Seemingly a rare species. I have only seen two 

 British specimens, one taken by Dr. Sharp at Brae- 

 mar, the other by myself at Rannoch. 



Thomson has doubtfully adopted the name of obtu- 

 sum for this insect, but it seems to me to be very dif- 

 ferent from the obtusum of Klug. Thus, it has the 

 antennas as long, if not longer than the abdomen ; in 

 obtusum they are only as long as the thorax ; the cly- 

 peus is black, in the other species white ; there is a 

 distinct white line on the pronotum ; the legs differ in 

 coloration and also the abdomen ; and, lastly, Klug's 

 insect is larger than pulveratum, while Fletcheri is 

 smaller. I can find no record of obtusum beyond the 

 original locality given by Klug, namely, Hungary. It 

 is possible that obtusum may have been founded on an 

 extreme variety of pulveratum, with which, indeed, the 

 description agrees except in one point, namely, the 

 description given of the colour of the legs, which are
