Platypodidce and Scolytidce. 109 



the elytra laterally from near the base to the apex is common 

 to both species, but in the present one there is a slight pro- 

 duction of the elytra at thesutural apex, of which the former 

 shows no trace. The regular and shiny punctures of the 

 elytral striae are more evident than in the preceding species. 



Genus Xyleborus, Eichh. 

 Xyleborus submarginatus, Blandf., ? . 



Hab. India, Belgaum (Andrewes) ; Ceylon (Thwaites in 

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

 ( Wallace) . 



A single specimen now taken in Sarawak (Mt. Mataug). 



Xyleborus sumatranus, Haged. 



Hab. Sumatra. 



One example from Sarawak (Mt. Matang). 



The following two new species were taken at Sarawak : — ■ 



Xyleborus comans, sp. n. 



Black, globose ; antennae and tarsi ferruginous. Front 

 nearly flat, thickly hairy with a transverse row of paler hairs 

 over the mouth ; rugose, the rugosity becoming longitudi- 

 nally confluent apically. Prothorax as broad as long, rounded 

 laterally and anteriorly, the front sharply depressed with 

 two large and two small prominent recurved tubercles on 

 the anterior edge, the surface rugose as far as the central 

 transverse gibbosity and punctured posteriorly, the whole 

 surface densely hairy with a very thick transverse ridge of 

 erect hair just before the base. Scutellum absent. Elytra 

 the same length as the prothorax, laterally rounded to the 

 blunted apex and furnished with obscure rows of piliferous 

 punctures ; an abrupt depression commences before the 

 middle and is margined by a few obscure tubercles, the suture 

 being raised and the apex margined on the apical half; the 

 fundus is furnished with more or less irregular piliferous 

 punctures. 



Long. 6 mm. 



Hab. Borneo, Sarawak (Mt. Merinjak and Quop) (G. E. 

 Bryant) . 



This species differs from Hagedorn's very incomplete 

 description of X. ur sinus in size, the frontal tubercles, the 

 basal prothoracic collar of thick hair, and the length of the 

 elytra, etc. It is no doubt allied to, but varies in many
