212 PTINID^E. 



which same island it has lately been taken more abundantly 

 himself and his brother. 



602. Casopus radiosus. 



Casapus radiosus, WolL, loc. cit. 199 (1862). 

 Casopus radiosus, Id., Cat. Can. Col. 238 (1864). 



Habitat Canarienses (Can.), sub lapidibus in elevatis et intermediii 

 rarior. 



The few examples which I have seen of this Casopus were taken 

 by myself in Grand Canary on the ascent to the Roca del Soucilho, 

 above San Mateo. It will doubtless be found as abundantly as most 

 of the other species, when the higher elevations of Grand Canary 

 have been carefully explored. 



603. Casopus subcalvus. 



Casapus subcalvus, WolL, loc. cit. 200, pi. viii. f. 3 (1862). 

 Casopus subcalvus, Id., Cat. Can. Col. 239 (1864). 



Habitat Canarienses (Hierro), sub lapidibus in intermediis parce lectus. 



Peculiar apparently to Hierro, the most western island of the 

 Canarian Group, where it occurs sparingly at intermediate altitudes. 

 It was taken by Mr. Gray and myself, near Valverde, and subse- 

 quently by the Messrs. Crotch ; and an example is now before me 

 which has been communicated by De Marseul from the collection of 

 M. de la Perraudiere, and which was met with by the latter in the 

 same island. 



Genus 191. DIGNOMUS. 

 Wollaston, Trans. Ent. Soc. Lond. 1. 201 (1862). 



604. Dignomus gracilipes. 



Dignomus gracilipes, Wott., loc. cit. 202, pi. viii. f. 4 (1862). 

 , Id., Cat. Can. Col. 239 (1864). 



Habitat Canarienses (Lanz., Fuert.), in stercore bovino, equino, came- 

 lino in aridis inferioribus latens. 



One of the rarest of the Atlantic Ptinidce, and confined apparently 

 to Lanzarote and Fuerteventura (the two eastern islands of the 

 Canarian Group) where it secretes itself within the dried dung of 

 cattle in arid sandy spots of a low elevation. This peculiarity of 

 habit, however eccentric for a member of the present family, is 

 nevertheless in accordance with what seems to be normal for at any 

 rate one more Canarian Ptinid namely, the Piarus basalts.
