Head and prothorax with outlines and punctures much 

 as on variabilis. Elytra moderately long, parallel-sided to 

 near apex, shoulders almost square and the width of widest 

 part of prothorax; with rows of fairly large punctures, in 

 distinct striae, both punctures and striae almost vanishing 

 near apex. Length, 2-2J mm. 



Hob. — Lord Howe Island. Type, I. 6152. 



Structurally fairly close to variipennis , but prothorax less 

 opaque and without a median line. From variabilis it differs 

 in being larger, elytra more parallel-sided, shoulders less 

 rounded off, and markings different. The head and prothorax 

 are obscurely castaneous, with the latter obscurely infuscated 

 on each side; the darker parts of the elytra are the base 

 (more narrowly dark about the shoulders than suture), the 

 sides (more noticeably about the middle than elsewhere), and 

 the suture, the sutural infuscation is mostly rather narrow, 

 but from about the middle to near the apex is conspicuously 

 dilated; the antennae are not much darker than the legs, 

 and their apical infuscation is but slight. Over the whole of 

 the upper-surface (which is glabrous) there is a vague metallic 

 gloss. Three specimens were taken on the summit of Mount 

 'Gower . 



Rhinosimus corticalis, Oil. 



A specimen from Cairns differs from a Richmond River 

 specimen that agreed with the type, by the rostrum (as seen 

 from above) being very considerably longer and noticeably 

 dilated towards the apex ; seen from the side it also appears to 

 be much thinner (only about half the thickness) and with the 

 length of the eye decidedly less than the length of the rostrum 

 in advance of the antennae ; in the Richmond River specimen 

 the length in front of the antennae is about equal to the 

 length of an eye. These differences are possibly sexual. 



Neosalpingus politus, Macl. (Corticaria, in error). 



Although referred to the Lathridiidae this species is a 

 Neosalpingus, and it occurs from the Richmond River to 

 Cairns. It has a few setae on the elytra, but they are distinct 

 only from the sides. 



Neosalpingus serraticollis, n. sp. 



Head and prothorax black with a brassy-green gloss ; 

 elytra almost black, under-surface and appendages (club 

 excepted) of a dingy brown. 



Head wide, with two shallow depressions in front; with 

 rather dense and small but sharply-defined punctures. Eyes 

 moderately large and basal. Antennae with an abrupt three- 

 jointed club. Prothorax about twice as wide as long, evenly
