CANARIAN COLEOPTERA. 141 



Genus 101. PARAMECOSOMA. 

 Curtis, in Ent. Mag. i. 186 (1833). 



239. Paramecosoma simplex. 



Paramecoaoma simplex, Wall., Cat. Mad. Col. 59 (1857). 



Habitat Fuerteventuram et Gomeram ; in ilia sub stercore came- 

 lino ad Eio Palmas mense Aprili ineunte a.d. 1859 tria specimiiia 

 deprehensi ; in hac cepit Dom. Crotch. 



This insect, which is rather common (amongst vegetable refuse) 

 around Funchal in Madeira, and which has so much the primd facie 

 aspect of a Cryptopliagus or a Typhct;a, is apparently scarce at the 

 Canaries ; though possibly it may" be only local, having hitherto 

 escaped our observation. At any rate I have myself taken, hitherto, 

 but three examples — namely, under camels' dung, in the Rio Palmas 

 of Fuerteventura, at the beginning of April 1859. Four more, how- 

 ever, were captured by Dr. Crotch, during the spring of 1862, at 

 Hermigua in Gomera. 



Genus 102. HYPOCOPRUS. 

 Motschulsky, Bull, de Moscou, 72 (1839) [script. Upocoprus]. 



240. Hypocoprus Hochuthii. 



Myrmecinomus Hochuthii, Chaud., Bull, de Moscou, ii. 206 (1845). 

 Monotoma caucasicum, Kolen., Melet. Ent. iii. 43 (1845). 



Habitat Teneriffam, a W. D. Crotch semel captus. 



A single example of this minute insect was taken by Dr. Crotch 

 in Teneriffe, during the spring of 1862. I can detect no appreciable 

 difference in it from the European H. Hochuthii, unless perhaps the 

 prothorax be a trifle more remotely punctured, and rather more im- 

 pressed in the centre behind. 



Regarding the affinities oi Hypocoprus, I believe that it has nothing- 

 whatever to do, except in external /aaVs, with Jfowotoma (despite the 

 assertion of M. Jacq. Duval, who appears to have mistaken the 

 structural features of the latter), but that all its details tend rather 

 to associate it with Paramecosoma, Leucohimatiicm, and Atomaria. 

 Indeed the proportions of its antennae, with their lax triarticulate club 

 and unequal intermediate joints, in conjunction with its slender limbs 

 and pentamerous feet, are (apart from minor details) far more sugges- 

 tive of the Atomarice than of the thick-limbed, tetramerous Monotomce, 

 with their 10-articulated antennae and compact, one-jointed club. 



Genus 103. ATOMARIA. 

 (Kirby) Stepli., ///. Brit. Ent. iii. 04 (1830).
