as the median length, sides strongly rounded; punctures 

 scarcely visible. Elytra briefly suboblong; with rows of 

 rather small but distinct punctures, on the sides set in rather 

 deep striae. Legs rather stout, front ones longer than hind 

 ones. Length (d, 9)? 1*75-2 mm. 



9 . Differs in being larger and more robust, head, eyes, 

 and jaws smaller, clypeus darker than labrum, abdomen 

 larger, more convex, and with a large apical fovea, legs 

 shorter and the front ones no longer than the hind ones. 



Hah. — Western Australia: Capel River (W. D. Dodd), 

 Vasse and Swan Rivers (A. M. Lea)., Type, I. 10929. 



The jaws of the male are stout and dilated on the front 

 edge, so that the labrum appears considerably smaller than 

 on other species, but on the female the jaws are much smaller 

 and the labrum of normal size; the distance between the eyes 

 of the male is about equal to the length of the six basal joints 

 of antennae (these being rather shorter and stouter than 

 usual), in the female the actual distance is the same, but 

 owing to the antennae being shorter -the distance is about 

 equal to the seven basal joints. The tarsi knees and hind 

 femora are the usual parts that are darker than the rest of 

 the legs, but sometimes the tarsi are no darker than the tibiae, 

 occasionally the middle femora are also dark; the opacity of 

 the head and prothorax (also parts of the under-surface) is 

 due to very fine shagreening, the elytra are highly polished. 



DiTROPIDUS TENUIFRONS, n. Sp. 



S . Black, head (infuscated about base), antennae 

 (club infuscated), palpi and legs (femora excepted) more or 

 less flavous. Glabrous. 



Zre«<i shagreened and with minute punctures. Eyes large 

 and close together. Frothorux about- thrice as wide as the 

 median length, sides strongly rounded ; punctures small, but 

 fairly distinct. Elytra short, sides rounded posteriorly; 

 striated almost throughout. Length (c?, 9)5 1*5-1' 75 mm. 



9 . Differs in having the head darker, and in the usual 

 particulars of the eyes, legs, and abdomen. 



Hah. — Northern Queensland (Blackburn's collection). 

 Cairns district (A. M. Lea). Type, I. 10864. 



In appearance somewhat like hrevicollis, but consistently 

 smaller, prothorax with distinct punctures (those towards the 

 base become somewhat aciculate), and elytral striae very 

 different; the apical half of the elytra has distinct striae 

 from the sides to the suture (deeper on the sides than 

 elsewhere), but about the base the short subsutural ones 

 change to series of punctures. The distance between the eyes
