Descrvplions of New Scolytldx. 223 



About the shape of A', interject as, Blandf., but smaller, 

 with the prothorax less narrowed towards the apes, 

 though as evidently rounded in front; the elytral 

 sculpture is characteristic and resembles somewhat that 

 of X. seminitens, Blandf., which species has not a sub- 

 quadrate prothorax. 



Xylehorus submarginatus, sp. n. 



Fem. Elongata, nitida, ferruginea, elytris versus apicera phis 

 minusve infuscatis ; prothorace oblongo, lateribus postice sub- 

 parallelis, apice obtuse rotundrfto, iude.'subquadrato, dorso medio 

 nodoso, postice nitido, obsolete punctato ; elytris striato-punctatis, 

 interstifciis rarius subtilius uniseriatina. punctatis et setosis, decliv- 

 itate obliqua, convexa, opaciore, iuterstitio 1"^ dilatato, utrinquc 

 medio tuberculato, et granulis nomiullis aute tuberculum et ad 

 apicem ornato, iuterstitio 3"^ obsoletius granulato, margiue inferiore 

 sat acuto crenato. Long. '2'4-2'5 mm. 



Resembling X. ^;«?t!(Z«s, Eichh., larger, darker iu colour, 

 the prothorax more parallel-sided and obtusely rouuded at 

 the apex, hence subquadrate. Elytra with the rows of punctures 

 more distinctly expressed, rather deeper, the punctures themselves 

 closer, the interstitial punctures finer, the setfe longer, declivity less 

 shining, the 1st interstice with a stronger tooth, preceded by a few 

 fine granules at the summit of the declivity and oue at the apex, 

 the 2nd interstice with two or three granules at the summit, the 

 3rd with a series on the declivity, its inferior margin distinctly 

 acute and crenate. 



Hah. India, Belgaum (Andrewes) ; Ceylon (Thwaites, 

 in Mus. Oxon.) ; Celebes (Wallace) ; New Guinea, Dorey 

 (Wallace). 



This species was referred to by me (Ann. Nat, 

 Hist. ser. 6, xv., p. 332) as a variety of X. parvidus. 

 Having since seen the type of that species and series 

 of both forms from Ceylon, I feel constrained to separate 

 it by the characters given above. It comes close to 

 X. dilatatns, Eichh., in many respects, but differs from 

 the description at least in possessing a prothorax which 

 is longer rather than shorter than that of X. j^nrvulus,
