Cali/ptomerus.] CLAVICORN-IA. 11 



CALYPTOIKERTJS* Eedtenbacher. (Comazus, Fairm.) 



This genus comprises four or five species from Europe and North 

 America ; they are found in vegetable refuse, flood rubbish, &c. ; the 

 larva of C. dubius (enshamensis) is described and figured by Ferris (Ann. 

 Fr. 1852, p. 574, t. 14, fig. 1-10) ; it is 2 mm. in length, of a livid colour, 

 setose at sides, broader in front and gradually narrowed behind, covered 

 with very small roughnesses or tubercles which are visible under a high 

 power ; the thoracic segments are proportionally large ; the anal 

 appendage is like a fleshy nipple, helping progression, and serving as a 

 point d'appui, when the insect wishes to move from place to place ; the 

 pupa is chiefly remarkable for the small space occupied by the abdominal 

 segments. 



C. dubius, Marsh, (enshamensis, Steph. ; cephalotes, Dej.). Short 

 oval, convex, of a lighter or darker testaceous colour, shining, thickly 

 clothed with very fine silky yellowish pubescence, very finely punctured ; 

 head very large, larger than thorax, antennae short, testaceous, with the 

 club slightly darker ; thorax very short, with the anterior and posterior 

 angles almost confluent, sides very short ; scutellum minute, triangular ; 

 elytra five times as long as thorax, scarcely dilated at sides, very convex 

 in front and sloped towards apex, with a sutural stria which is abbreviated 

 in front, sutural angle somewhat acuminate ; under-side testaceous, 

 pubescent ; legs pale. L. f mm. 



In haystack and flood refuse, &c. ; local but not uncommon in some places; Croydon, 

 Ripley, Lee, Micklebam, Birdbrook (Essex); Hastings; GlanvillesWootton ; Wivenhoe 

 (tidal refuse) ; Ely ; Wicken Fen (in sedge) ; Knovvle near Birmingham (on damp 

 walls) ; Repton ; Northumberland district, rare, sea-coast near Hartley ; Scotland, 

 not common, amongst straw in outhouses, Solway, Tweed and Forth districts; 

 Ireland, Rathkurby, Waterford, near Dublin, &c. 



CXi AMBUS, Fischer. 



About a dozen species are comprised in this genus, five of which are 

 found in Europe, and the remainder have been recorded from North 

 America, the Canary Islands and Ceylon ; it appears therefore to be rather 

 widely spread, and is probably much more extensive than at present 

 known ; the species are very minute convex insects, and have the power 

 of rolling themselves up into a ball ; they differ from Calyptomerus in 

 having the antennae 9-jointed, and in the smaller head and longer thorax ; 

 the metasternum is excavate in front for the reception of the head, and 

 the posterior coxae are semicircular ; the species are found in hot-beds, 

 and among moss, dead leaves, and vegetable refuse generally. 



I. Elytra more or less distinctly pubescent. 



i. Pubescence close, fine, and short ; size smaller . . . C. PUBESCENS, Redt. 

 5i. Pubescence long and diffuse ; size larger C. ARMADILLO, De. G. 



II. Elytra entirely without pubescence C. MINUTUS, Sturm.
