slightly bulged out at the base on one side ; the remaining 

 joints are simple or almost so. 



Heteromastix dolichocephalus, n. sp. 



9 . Black ; elytra reddish-flavous, suture and tip black ; parts of 

 " coxae obscurely diluted with red. Moderately clothed with greyish 

 pubescence, very short on head but moderately long elsewhere. 



Head longer than wide, with several feeble impressions in front ; 

 punctures small and indistinct. Eyes small and not prominent. 

 Antennae rather short, moderately stout, median joints stouter than 

 the others, but simple. Prothorax about once and one half as long 

 as wide, disc rather strongly convex, sides rather strongly margined, 

 all the margins more or less angular and distinctly raised, widest 

 near apex, impunctate. Scutelhmx transverse. Elytra not much 

 wider than widest part of prothorax, almost conjointly rounded at 

 apex, with dense but rather small and subrugose punctures. Leys 

 moderately long ; tarsi 4th joint wide and deeply bilobed ; claws 

 almost simple. 

 Length 6 mm.

It may be necessary to place this species in a new genus 

 eventually, but as I only know the female I have not con- 

 sidered it advisable to propose one now for its reception. 

 The head may normally be partially concealed by the 

 prothorax, but in the type its full length is exposed ; in 

 any case, however, it is much longer than in any other 

 species of Heteromastix. I cannot see the buccal append- 

 ages clearly, but behind the mentum is a deep sub-conical 

 excavation, the base of which is on the mentum. If the 

 tibiae are really spined at the tip, the spine is so small as 

 to be quite concealed. The dark sutural marking is on 

 each elytron rather more than one-third of its width at the 

 base, but at the apex it is only about one-fifth.

 The species of this genus are all of small or comparatively 

 small size ; and usually reddish, with metallic-blue, purple 

 or green markings. The antennae are short, fairly stout
