146 Mr. Arthur M, Lea's Revision of the 



coarsely and somewhat rugosely punctate. Penultimate segment 

 of abdomen deeply semicircularly excised. 

 Length 4^ mm. 



Hah. N. S. Wales : Jenolan {A. M. Lea). 



Differs from the species I suppose to be vidoriensis in 

 being smaller and wider, legs somewhat differently coloured 

 and antennal joints (especially the 9th-llth) differently 

 proportioned. The elytra are more coarsely sculptured 

 than in gagaticeps, to the female of which it bears a striking 

 resemblance ; in fact, but for the abdomen being essentially 

 masculine I should have imagined the unique specimen 

 before me to be a female of that species. The elytral 

 punctures are the same size but much denser than in 

 fnsicornis ; the rugose appearance is caused by small 

 transverse wrinkles, but each puncture is usually clearly 

 defined. From pauxillus, it ditfers in being more compact, 

 antennae much shorter, basal joints pale, the 2nd propor- 

 tionately longer, elytral punctures more sharply defined, 

 legs not entirely black, prothorax less transverse, etc. 



Heteromastix latus, n. sp. 



^. Black; prothorax, parts of muzzle, mandibles, front legs 

 (tarsi, apex of tibiae and part of base of femora infuscate), middle 

 knees and base of hind tibiae more or less flavous. 



Head strongly transverse. Antennae somewhat as in nigripes. 

 Prothorax about twice as wide as long, sides almost regularly 

 rounded. Elytra shorter and wider than usual, densely and rugosely 

 but rather finely punctate. Penultimate segment of abdomen semi- 

 circularly excised. 



Length 5j mm. 



5. Differs in being slightly wider, prothorax more transverse, 

 antennae shorter, 11th joint not constricted in middle and abdomen 

 simple. 



Hob. N. S. Wales : Forest Reefs {A. M. Lea). 



I have referred this species and nigt'ipes to the group 

 having simple antennae, although the apical joint is some- 

 what constricted in the middle in the male, apparently 

 denoting an approach to the group about gagaticeps. The 

 10th joint, however, is perfectly simple. The antennae of 

 this species are much as in nigripes, except that they are 

 somewhat shorter and stouter and with the 11th joint 

 shorter and very feebly constricted in the middle ; but the
