a short produced piece on one side, sixth to tenth each with 

 a long ramus, eleventh as long as ramus of tenth. Prothorax 

 with a vague depression in middle, and a still more vague 

 one on each side of same. Elytra each with four feeble 

 longitudinal elevations. Length, 10-1 H mm. 



flab. — Queensland: Winton ( — Higgins). Type in 

 Queensland Museum; co-type, I. 5924, in South Australian 

 Museum. 



With the general appearance and outlines of the pre- 

 ceding species, and also with the long antennal rami com- 

 mencing on the sixth joint, but differs from that species in the 

 eyes being wider apart (their distance at the nearest point is 

 about equal to the length of the second joint of antennae), 

 five basal joints of antennae darker than the others, and the 

 mandibles and under-surface entirely black. In general 

 appearance this species even more closely resembles a 

 T rigonotomoides than does occid entails, but its head is quite 

 as distinctly elevated above the front of the prothorax as is 

 that of that species. The punctures on the upper-surface are 

 very dense and small, but are normally concealed by the 

 clothing. 



Pelecotomoides. 



With the exception of the typical species (conicollis), in 

 which the differences in the antennae are great, I am unaware, 

 apart from dissection, as to how the sex of unique specimens 

 of this genus may be determined. With several species there 

 are slight differences in the size and approximation of the 

 eyes, and very slight differences in the width of the front tarsi 

 and of the antennae, but these are not available to distinguish 

 single specimens. Gerstacker referred the species known to 

 him to two sections : — 



1. Antennae with four basal joints simple, or narrower 



than the others, nuda, Gerst. 



2. Antennae with five basal joints simple, or narrower 



than the others. senilis, Gerst.; lutea, Gerst.; 

 sericea, Gerst. 



Of these nuda is commented upon below; sericea should 

 be distinct by the prothorax with 'foveola disci sat profunde 

 impressa," and senilis by the very short third joint of 

 antennae ; lutea is evidently a very small and ordinary-looking 

 species that might be any of several species in the Museum, 

 including some named by Macleay. 



In addition to the species here described there are others 

 (mostly from Queensland) in the Museum that are probably 

 new, but at present it appears better to pass them over rather 

 than to risk redescribing several imperfectly-characterized 

 species.
