extending to apex of elytra; tibiae straight. Length 3 J, rostrum 1; 

 width 1^ mm.

A small dingy species which at first sight appears to belong to 

 Melanterius (it resembles such species as macidatus, acacice and 

 tristis). The antennae are decidedly aberrant, but it has not been 

 considered necessary to generically isolate it on that account. 



Mecistocerus denticulatus Pasc; Mast. Cat. Sp. No.5412. 



Hah. — '' Port Bowen " (Pascoe). 



I am confident that I have not seen this species. The male is 

 described as having a number of small spine-like teeth on the 

 anterior femora and tibia?. "^^

Head small, convex, partially concealed. Eyes large, triangu- 

 larly-ovate, widely separated above and moderately beneath, 

 rather coarsely faceted. Rostrum long, thin and moderately 

 curved. Ante^mce thin; scape inserted nearer apex than base of 

 rostrum and the length of funicle; club elongate-elliptic. Pro- 

 thorax moderately or scarcely transverse, sides rounded, base 

 bisinuate, apex produced, ocular lobes almost rectangular. 

 Scutellu7n distinct. Elytra elongate-cordate, not much wider 

 than prothorax. Pectoral canal moderately deep and narrow, 

 terminated in metasternum. Mesosternal receptacle absent, the 

 intermediate coxse exposed internally. Metasternum slightly 

 shorter than the following segment; episterna rather wide. 

 Ahdomen with the four basal segments drawn slightly backwards 

 at the sides, the 1st almost as long as 2nd and 3rd combined, 

 intercoxal process moderately wide and rounded, apical suture 

 incurved; 3rd and 4th combined slightly longer than 2nd and 

 considerably longer than 5th. Legs rather short; femora moder- 



* Since this was written I have seen a male, and the spines of its femora 

 and tibiae render it very distinct.
