 Tr. Aphodioides. Latreille.—Steph. Catal. 114. No. 1179. 



Black, shining : thorax deeply punctate : elytra striated : antennae and legs pale- 

 brown. 



I possess a fragment only of this singular insect, which I obtained from the 

 collection of Mr. Marsham. 



A single perfect example only of this insect has come beneath 

 my observation ; it was taken as mentioned below, and is in the 

 collection of the British Museum: — the locality of my injured 

 specimen I know not. " In the New Forest, near Lyndlmrst." — 

 Mr. D. Bydder. 



Genus CC. — Trox, Fabricius. 



Antennae concealed during repose beneath the sides of the thorax, anteriorly, 

 ten-jointed 3 the basal joint very large, subconic, a little bent, and clothed 

 with rigid hairs ; second also stout, subglobose ; five following short, rather 

 slender, the third the longest; the remainder forming a triphyllous club, 

 with the lamellae rather long. Palpi rather stout, the terminal joint ovate : 

 labrum semicircular, hairy: mandibles with the apex bent, acute: head short, 

 deeply sunk in the thorax, which is sinuated behind, and rugose : body 

 subovate, very rugged, convex, flat beneath: legs short, stout, generally 

 pilose: tibia; with acute spurs at the apex : tarsi short ; claius rather large. 



As a genus, Trox may be known from the foregoing by having- 

 the basal joint of its antenna? very robust and pilose, the antenna? 

 themselves concealed during the repose of the insect beneath the 

 anterior angles of the thorax, the body curved and very rugose ; 

 the mandibles with the apex acute, simple, the claws rather large; 

 the labrum semicircular, &c. : — like the rest of the family, they 

 chiefly inhabit sandy or gravelly places during the spring. 



Sp. 1. sabulosus. Niger, thorace incequali, elytris substriatis, interstitiis al- 

 ternis elevatioribusfasciculato hispidis. (Long. corp. 4 — 4^ lin.) 



Sea. sabulosus. Linne.— Marty n, pi. 3. /. 26. — Tr. sabulosus. Steph. Catal. 

 114. No. 1180. 



Black : clypeus semiorbiculate, punctate : thorax very unequal, channelled, 

 thickly punctured, and bordered throughout with rufous cilia: elytra coarsely 

 punctate-striate, with the alternate interstices more elevated, and adorned 

 with short tufts of red-brown hairs, but less evident on the disc. 



Larger than the two following species, from which it may be known by having 

 the clypeus semiorbicular, the elytra more rugose and deeply striated, &c.
