margins sornewhat dilated and thickened near apex. Elytra 

 almost paralUl-sided to near apex; with dense and small but 

 rather sharply defined punctures. Legs rather long and thin. 

 Length, 3.20 — 3,5 mm. 



Hab. — Queensland: Glen Lamington (Dr. E. Mjöberg). 

 Type in Stockholm Museum. 



The three joints at each end of the antennae are påle, 

 the others are more or less infuscated; the tenth and eleventh 

 joints are so closely applied together that, as they are partly 

 obscured by pubescence, it is difficult to see their true shapes, 

 the eleventh, however, is somewhat dilated at the base, ap- 

 proaching the helmet-sbape of that of H. gagaticeps and of 

 other species; the fourth and fifth joints are the most re- 

 markable ones, and readily distinguish the species from all 

 other known ones. 



Heteroniastix diorycerus sp. nov. — Fig. 10. 



(^ Black; prothorax, sciitellum, legs (tartii more or less 

 infuscated), three or four basal joints of antennae, and most 

 of palpi flavous. With very short pubescence. 



Fig, 10. Heteroniastix diorycerus Lea. 3 terminal joints of antennae from 



different points of view. 



Head with two faint interocular impressions. Antennae 

 moderately long, first joint as long as second and third 

 combined, third slightly longer than fourth, and twice the 

 length of second, sixth to ninth feebly transverse, tenth and 

 eleventh distorted. Prothorax about twice as wide as long, 

 sides and base conspicuously margined, the former slightly 

 dilated to near apex, but not thickened. Elytra almost 

 parallel-sided to near apex; with dense and small rugose 

 punctures. Length (c?$), 4—4,5 mm. 



5 Differs in having the head somewhat smaller, antennae 

 shorter, thinner, with simple joints, and abdomen not notched.
