Long. 3 mm. 



Hob. S. E. Borneo : Martapura (Doherty). 



This is a small insect, with the upper surface stronjrly 

 punctured, as in H. servilis, but more finely and closely. 

 The sides of the proiiotum are much less strongly curved 

 than in that species or H. latipes, beinp; very gently rounded 

 in front and nearly straight behind, with the hind angles 

 right angles. The antennae are like those of FI. latipes, 

 but a little more slender, with joints 2 and 3 elongate, 

 4 to 8 beadlike and about as long as they are wide. The 

 legs are slender and the tibiae nearly straight, but those 

 of the front and middle pairs a little dilated towards the 

 extremities. 



I have seen only a single male specimen. 



Heliobletus acuticollis. 



Totns forrugineus, antennis (basi exccpto) nigris; sat robiistus, 

 minutissime punctulatus, nitidus, iibiquo griseo-pubescens, pronoto 

 lato, subtilissime haud crcbre punctulato, lateribus bisinuatis, 

 nngulis posticis productis, acutis; elytris paxilo minus minute sed 

 leviter punctatis : 



(^, antcnnis crassis, artioujis .3'^-8° tvansversis, compactis, 9° 

 magno, ovali, subtus leviter planato, jiedilxis gracililius, til)iis

Hab. S. E. Borneo : Martapura (Doherly). 



The general shape and colouring are exactly as in the other 

 species, but the legs (of the (J) are quite simple and the upper 

 surface is shining and very finely and lightly punctured, 

 especially upon the pronotunr, the sides of wliich are dis- 

 tinctly bisinuated and the hind angles acutely produced. 

 The antennae are massive, joints 3 to 8 very short and 

 compact, 9 very large, almost regularly oviform and not 

 excavated, 10 transverse, very slightly produced inwardly, 

 and 11 shortly oval. The legs are slender, the tibiae 

 almost straight and not at all dilated.
