were damaged. Three have also been found amongst Dr. Fordham's 

 incognita. From lack of time to investigate this insect himself 

 Dr. Sharp suggested that I should undertake the matter. He re- 

 marked that he did not form any opinion about it, except that he 

 expected the insect would turn out to be a new genus, a forecast which 

 has jjroved to be correct. I have to thank him very much for his kind 

 assistance, as without his help I should have hesitated to deal with an 

 unknown individual of this difficult section of the Staphylinidae. I have 

 named the species after Dr. Fordham, to whose congeniality in sending 

 me the batches of material the discovery of the insect was primarily due,

NOTES ON THE COLEOPTEEOUS GENUS I8CHALIA Pascoe 



(FAM. PYROCHROIDAE), WITH DESCRIPTIONS OP TWO NEW SPECIES 



FROM THE PHILIPPINE ISLANDS.

The genus Isclialia was erected by Pascoe In 1860 (Journ. of Ent. i, 

 p. 54) for a single species, I. indigacea Pasc. from. Borneo, and was 

 placed by him, with some doubt, in the family Pedilidae. 



Two years later Leconte described a new genus and species, Eu- 

 pleurida costata from N. Carolina, which he placed in the Pyrochroidae, 

 though the genus was subsequently (1873) smik b}'' him as synonymous 

 with Isclialia Pasc. In Champion's Supplement to Gemminger and 

 Harold's Catalogue (1898) and in Pic's Catalogue of the Pedilidae 

 (Junk, Coleopt. Catal. pars 26, 1911) this synonymy is retained. 



Of late years numerous other species have been added to Isclialia, 

 one from Vancouver Id. and six from the Malay region, in addition to 

 the two described below. The American species differ from their Oriental 

 allies in being wdngless,* and in lacking the short humei-al costa, dorsal to 

 the two lateral costae, characteristic of the Eastern species, thus affording 

 grounds for the I'etention of Eupleitrida Lee. as a distinct genus. 



As noted above, the combined genera have been variously assigned 

 to the Pyrochroidae and to the Pedilidae, but by most recent writers — 



* I. patagiata Lewis, from Japan, shows an approach to F.upleurida in that the wings »re 

 incompletely developed and the thorax is swollen and convex in front.
