212 REVISIOK OF PTEUOHEL^US (coiltd.) AND SARAOUS, ETC., 



rowly reflexed laterally, less evident at base and apex; disc deeply 

 canaliculate, surface microscopically punctate, sometimes with a 

 small fovea on each lobe. Scii,tellii.m prominent, semicircular. 

 Elytra twice and one-half as long as prothorax, and slightly 

 wider, very cylindric and convex, humeri obsolete, or barely 

 indicated by epipleural fold; striate, with six well-mai'ked stria? 

 on each elytron, and three faintly impressed on sides, iitterstices 

 of disc distinctly convex, apical segments of abdomen minutely 

 punctate, basal segments and epipleurae smooth, intercoxal process 

 rounded, prosternum finely transversely strigose, mesosternum 

 rugose, with a smooth carina in the middle, foi-e tibije curved, the 

 other tibife straight; femora without sexual charactei's, front 

 femora swollen. Dimensions, 15-18 x 4-4:-5 mm. 



Hab. — Queensland, widely distributed, (Atherton, Toowoomba, 

 Killarney, (fee.) 



I have long had this species under observation, and, in January 

 of the present year, Mr. Sloane and I found it very common at 

 Killarney (South Queensland). It differs from the equally com- 

 mon southern species, 0. Behri Germ., in its still narrower, more 

 convex and cylindrical form, its bronze coloui^, its convex elytral 

 interstices, and nai'rower eyes, inte7- alia. Twenty-seven speci- 

 mens under observation show little indication of sexual characters, 

 thougli the male has been determined by dissection. [I have not 

 been able to detect the armed femora of the male in 0. Behri 

 Germ., mentioned by Bates in his tabulation (Ent. Mo. Mag., 

 xvi., p. 30); nor is it the case that the epij^leural fold is not visible 

 at the humeri. Also in Germar's description, the Avords " coleop- 

 tera thorace pauUo angustiora " are true of only some specimens. 

 In general, the elytra are wirier than the prothorax, and the 

 species is wider and flatter than 0. cylindricns. The range of 

 0. Behri is very wide; I have specimens from Forbes, New South 

 Wales, and Eucla, South Australia.] 



Otrintus Fergusoni, n.sp. 



Elongate-ovate, bronze, very nitid; apical joints of antennae 

 fuscous, tarsi and tibiae (at apex) clothed with red tomentum, 

 underside nitid black.
