Habitat in domibus TenerifFce et Hierro, minus frequens sed certe 

 introductus. * 



For the exact distinctions between the present species and the last 

 one I must refer to my Madeiran Catalogue (cited above). The 

 C. affinis, 80 far as I have observed hitherto, occurs (as in Madeira) 

 exclusively about houses — being clearly an imported insect into these 

 islands. In such positions I have taken it at S''' Cruz and Orotava in 

 Teneriife, and at Valverde in Hierro, — in the former of which islands 

 it was also captured by Mr. Gray and Dr. Crotch. 



234. Cryptophagus obesulus, n. sp. 



C. breviter oblongus, fusco-ferrugineus, pube sat elongatfi vix depressa 

 dense vestitus ; prothorace subopaco, valde profunde et dense punc- 

 tato, ad latera subrotundato, denticiilo medio acuto ; elytris paulo 

 clarioribus, oblongis, dense punctatis. — Long. corp. lin. ^1. 



Habitat Lanzarotam et Fuerteventuram ; in ilia sub recremento 

 farris circa basin acervorum tritici sparse, sed in hac etiam sub ster- 

 core camelino ad Rio Palmas captus. 



From the C. affinis the present Cryptophagus may be known by 

 its rather smaller size, relatively more deeply and closely punctured 

 surface, and by its (subopake) prothorax having the anterior ridge 

 and central denticle less prominent or defined. The space, moreover, 

 between the latter and the hinder angle is more coarsely crenulated. 

 Small examples of it might sometimes be almost confounded, at first 

 sight, with the following species ; nevertheless it is certainly distinct 

 from that insect. It may be known from it by being on the average 

 rather larger, broader, and more parallel ; by its pubescence being 

 a little longer, denser, and less depressed ; by its punctation being 

 altogether somewhat deeper, and closer; by its prothorax being ^ro- 

 portionally a trifle wider, shorter, and less straightened at the sides ; 

 and by its wings being fuUy developed. I may add that it was 

 examined by Dr. Kraatz, who regarded it as new. I have taken it 

 rather commonly from beneath the refuse around the base of corn- 

 stacks at Haria, in the north of Lanzarote, and from under camels' 

 dung in the Rio Palmas of Fuerteventura, — to which two islands it 

 would seem (so far at least as has been observed hitherto) to oe pe- 

 culiar. In Lanzarote it was likewise found bv Mr. Gray.
