226 Mr. Walter F. H. Blandford's 



The shape of the elytral apex is Hke that found in 

 many species of Pterocyclon, and the species may be 

 regarded as intei^mediate between such forms as X. con- 

 fusus, Eichh., and its allies, and X. fallax, Eichh. 



Xyleborus laticollis, sp. n. 



Fem. Subelongata, nitida, badia, elytris piceo-ferrugineis ; pro- 

 thorace amplo, suboblongo, lateribus leniter, apice fortiter rotund- 

 ato, dorso transverse subelevato, postice subtiliter sparsJm 

 punctate ; elytris prothorace angustioribus, postice angustatis, 

 striato-punctatis, interstitiis lineato-punctatis, postice tuberculatis 

 apice fortiter oblique declivi, subimpresso, fundo inermi, lateraliter 

 in linea interstitii 3i seriato-tuberculato. Loug. 2-7 mm. 



Female. Subelongata, shining, sparsely pilose. Head bright- 

 brown, front subcouvex, dull, punctured, with a fine subelevated 

 median line, mouth thinly fringed. Prothorax a little longer than 

 broad, ample, broadly rounded in front, the sides nearly straight, 

 inflexed slightly towards the rounded hind-angles, base truncate ; 

 surface cylindrical behind, convex and declivous at the apex, with 

 a scarcely elevated transverse nodus before the middle, bright- 

 brown with a darker shade towai-ds apex, scarcely hairy, granulate 

 in front, behind shining, finely and sparingly punctured, with a 

 smooth median line. Elytra narrower than the prothorax and a 

 third longer, the shoulders subobtuse, the sides nearly parallel to 

 the middle, thence narrowed, the apical margin truncate in the 

 middle; surface cylindrical, piceo-ferruginous, shining, with thin 

 rather long hairs, rather strongly punctured in substriate rows, the 

 sutural stria markedly impressed shortly after the base, interstices 

 flat, with as strong but more remote uniseriate piliferous punctures, 

 replaced by small tuberculate points before the declivity ; the latter 

 beginning at the apical third, oblique, flattened, shining, indistinctly 

 striate, its fundus unarmed, the 3rd interstice callose and tuber- 

 culate, the outer interstices less strongly tuberculate. Underside 

 and legs testaceous, the abdomen darker. 



Hah. India, Kanara (Andrewes). 



This species belongs to the subdivision of which X. 

 saxeseni, Ratz., forms part, but is quite different from 

 that species in sculpture and in the much larger and 

 more ample prothorax, which looks almost out of pro- 

 portion in comparison with the elytra.
