Longicorn Coleoptera from Borneo. 137 



marginato ; scutello elongato-triangulari, nigro ; pectore abdo- 

 mineque violaceis. 

 Long, 20 lin. 



Entirely deep ochraceous above. Antennae with the three 

 apical joints duskj. Eyes black. Thorax densely rugose on 

 the disk, the lateral spine strong, the anterior and posterior 

 borders black ; the underside is bluish black with a yellow 

 transverse stripe. Elytra very long, not much attenuated 

 posteriorly, densely rugulose, but not quite so coarsely so as 

 the disk of the thorax ; the apices scarcely truncate. 



Hob. Borneo. 



This species much resembles P. spimcoUis, but has the 

 head and thorax differently coloured, the apices of the elytra 

 are not " broadly truncate," and the anterior and posterior 

 coxae are yellow. 



Pachyteria basalis, sp. n. 



P. nigra, subnitida ; antennarum articulis sex apicalibus elytrorum- 



quQ dimidio basali flavis ; thorace rufo. 

 Long. 15 lin. 



Very close to P. LamM, Pascoe (Proc. Zool. Soc. 1866, 

 t. xliii. f. 6), but differs, so far as one can judge from the 

 figure and description, in having six instead of seven joints of 

 the antennffi yellow. The elytra are relatively longer. The 

 underside is aeneous- black, the abdomen tinged with piceous ; 

 each segment with a spot at the side of greyish-yellow pubes- 

 cence. 



cJ . Abdomen with the 5th segment broadly emarginate ; 

 6th segment below very deeply emarginate, the sides of the 

 emargination parallel ; above triangularly notched. 



$ . Abdomen with the 5th segment below notched on each 

 side. 



Hab. Borneo, Sarawak. 



Pachyteria ruJicolUs, sp. n. 



P. viridi-senea, nitida ; antennarum articulis tertio ad quintum 

 flavis ; thorace laete rufo ; elytris ultra medium utrinque plaga 

 elongata velutina ; corpore subtus plus minusve pubescentia griseo- 

 flava ornato. 



Long. 12 lin. 



The six apical joints of the antennae are deep blue-black. 

 The thorax is bright red, with moderately strong punctures 

 not very thickly scattered over the surface ; the extreme ante- 

 rior and posterior margins are edged with black ; the lateral 

 spine is short, tubercular. The elytra are bright metallic
