In my unique example of this species the mandibles are 



•entirely covered by the la brum. Rather close to H. SIoa?iei, 



Blackb., but differing from it inte?' alia by the black club of its 



antennae, the nearly black color of its meso- and meta-sterna (in 



strong contrast to the testaceous prosternum and abdomen), its 



•evidently less transverse prothorax, and its much less closely 



punctured pronotum (the punctures of which even close to the 



iront margin are separated i7iter se by more than the length of 



the diameter of individual punctures. There is a little vague in- 



fuscation on the elytra in the scutellar region and behind the 



middle, also forming a wide margin on the scutellum itself.

H. darwinensis, sp. nov. Minus lata ; obscure brunneo-testacea, 

 meso- et meta-sternis nigricantibus ; subpubescens ; capite 

 coriaceo subtiliter sat sparsim punctulato ; prothorace quam 

 longiori fere duplo latiori, antice sat fortiter postice vix 

 manifeste angustato, supra coriaceo et sparsim (in medio 

 disco sparsissime) subtiliter punctulato, lateribus angustis- 

 sime reflexo-marginatis leviter arcuatis, angulis omnibus 

 obtusis ; scutello coriaceo sparsim punctulato , elytris quam 

 prothorax vix latioribus circiter duplo longioribus, coriaceis, 

 sat sparsim (prope scutellum paullo minus sparsim) sat sub- 

 tiliter punctulatis, lateribus parum arcuatis, ad apicem trun- 

 catis ; metasterno postice in medio late angulatim emar-

 This species is certainly very close to the preceding [H. sparsior) 

 but I cannot regard them as identical. H. darwinensis is very 

 ■evidently smaller than sparsior, of less wide build, its antennal 

 club testaceous, its prothorax a trifle more transverse and with a 

 narrower reflexed margin, its pronotum evidently more finely and 

 sparsely (on the middle of the disc extremely finely and sparsely) 

 punctured. It diff'ers from Sloanei, Blackb., by the same charac- 

 ters that distinguish sparsior (except the colour of the antennal 

 club). The infuscation of the upper surface is much as in 

 sparsior.
