On new Species o/Pyrocliroidte/rom Borneo. 317 



XXXVII. — Tioo new Species o/Pyrocliroiilnc! (Coleoplei'a) 

 from Borneo. By K. G. Blair. 



(Published by permission of the Trustees of the British Museum.) 



In a collection of Colcopt.'ra recently brought back hy 

 Mr. G. E. Bryant from Borneo are two new species of 

 ryrocliroidjB ; and since only three species of this family, 

 including the doui)tfuI genus IscIiaHa, have liitiierto been 

 known from the island, it may perhaps be as well to describe 

 them. Tiie types have been generously presented by 

 Mr. Bryant to the British Museum. 



Pseudopyrochroa moultoni, sp. n. 



Black, with the exception of the elytra, of which tlie basal 

 two-thirds are red. The junction between the black and red 

 is rather sntfused, but the black patch extends forwards as a 

 narrow costal stri|) beyond the middle of tiie elytron. The 

 elytra are separately rounded at the tips and strongly costate 

 or striped. 



The head of the male is deeply excavate between the eyes, 

 the sides of the excavation being almost parallel and slightly 

 curved, and its cavity filled with dark brown hairs. The 

 antenuie have the first two joints rather shiny, the rest 

 opaque and velvety. The first joint is strongly incrassate, 

 the second sub lentate within ; the thiid and succeeding 

 joints stout, thickened towards the apex, so as to form a stout 

 lobe within, while from the underside of the apex arises a 

 slender bianch (ef. P. diversicornis, Blr., Ann. & Mag. Nat. 

 Hist. (8) xiii. pi. xii. fig. 10). 



The antenufe of the female are stouter, the first two joints 

 scarcely less velvety than tiie rest; the third to tenth are 

 produced within into stout but successively longer apical 

 branches. 



Length 9-13 mm. 



IJab. Mt. Matang, Lundu, Kuching, Mt. Sibau. 



E'lom. Ps. apicipennis, Blr., which is the only other de- 

 sci-^oed Bornean species with a similar type of coloration, it is 

 distinguished b}' the elytra being flatter and strongly dehiscent 

 at the apex, more strongly striped, and by the different size 

 and shape of the apiciil b!ack patch. In my key to this genus 

 (Ann. & Miig. Nat. Hist. (8) xiii. p. 319) it should be placed 

 next to ohscuiicoUis, Pic, but from this it differs in the struc- 

 ture of the anteuiue in the male, in the form of the frontal
