Sp. 1. Omma Stanleyi. Totum fuscum, obscurum, lanugine aurea 

 sparsim tectum; omnino verrucosum ; elytra seriebus 10 punc- 

 torum prof undorum fere conjunctorum impressa. (Corp. long. "85 

 unc. ; lat. "25 unc.) 

 Brown without gloss, sparingly covered with a short golden 

 pilosity; all parts of the insect are rugose, resembling shagreen; 

 in size and habit, the form being very depressed, the insect 

 much resembles some of the heteromerous beetles, particularly 

 Plateia orientalis of De Haan, (the Tenebrio complanata of 

 Dalman,) and it possesses a superficial similarity to the nor- 

 mal Cucuji, but from both of these families it is at once distin- 

 guished by its very distinctly 5 -jointed tarsi, the 1st joint 

 being elongate and all of them fully developed : the structure 

 of the mouth will be found to approach that of the anomalous 

 genus Rhysodes of Latreille (the Clinidium of Kirby) ; the si- 

 milarity is particularly observable in the structure of the max- 

 illae and in the mentum, which is very broad, porrected, and 

 covering the labium : the tarsi and the lateral and nearly sphe- 

 rical eyes are those of the genus Capes of Fabricius. The 

 prothorax has a deep transverse impression posteriorly. The 

 elytra have five double rows of very deep and nearly conti- 

 guous impressions : at the bottom of each impression the 

 elytron is thin and semitransparent : between each pair of 

 rows is a slightly elevated ridge. 



Inhabits Australia ; a single specimen brought to this country by 

 Lady Parry is in the cabinet of Mr. Melly. The insect will not 

 range with any described family of Coleoptera.
