Genus 314. BOLITOBIUS. 



(Leacli) Stephens, ///. Brit. Ent. v. 171 (1832). 



851. Bolitobius luridus, n. sp. 



B. ellipticus, lurido-testaceus, ctipite utrinque, i^rothorace in disco, 

 elytris hinc inde (prtesertim in djsco utrocjue postico) abdominis(ine 

 segmentis ad basin plus minus obscure et suffuse infuscato-nebu- 

 losis ; antennis apicem versus nigrescentibus paulo incrassatis, basi 

 pedibusque testaceis ; prothoracis punctis 4 postieis ad marginem 

 sitis, minutis (cxternis a^gre observandis, ad angulum utrunuiue 

 ipsum positis) ; elytris amplis, postice substriatis, seriebus tribus 

 parcissime (sc. circa 4— G) punctatis, — Long. Corp. lin. 1|— 2. 



Habitat in intermediis sylvaticis Teneriifoe, rarissimus. 



The elliptic outline and compai-ativeh/ large head and elytra of this 

 Bolitobius, in conjunction with its hn-id-testaceous hue (the head on 

 either side, the disc of the pronotum, a considerable portion of the 

 elytra, and the hinder half of each of the abdominal segments being 

 more or less obscurely clouded, or infuscate), will serve to charac- 

 terize it. The four punctules at the base of its prothorax are ex- 

 tremely minute, and situated quite on the margin itself (the outer 

 pair being very difficult to detect, from being placed exactly at either 

 posterior angle) ; and its elytra, which are substriated behind, have 

 their three longitudinal lines most remotely punctured (the punctures 

 being usually not more than from about four to six in number). It 

 appears to be extremely rare, and confined to the sylvan districts of 

 Teneriffe — the few specimens which I have seen having been taken 

 by myself at the Agua Garcia and in the laurel- woods above Taga- 



nana. 



852. Bolitobius filicornis, n. sp. 



B. elongato-ellipticus, angustus, capite parvo, nigro, prothorace clare 

 sed elytris infuscate rufo -testaceis, abdomine piceo (segmentis basi 

 singulatim rufescentioribus ) ; antennis subfiliformibus, nigro-fuscis, 

 basi pedibusque testaceis ; prothoracis pmictis 4 postieis vix ad mar- 

 ginem ipsissimum sitis, distinctis ; elj'tris breviusculis, seriebus tri- 

 bus distincte punctatis. 



Variat (immaturus?) capite, elytris antennisque pallidioribus. —

Habitat in Canaria, Teneriffa et Hierro, rarissimus. 



The smaller size, very much narrower and less elliptic outline, and 

 less developed elytra of this species, added to its smaller and blacker 

 head, its rufo-testaceous prothorax and elytra (the former of which 

 is clear and immaculate, whilst the latter are more or less infuscated) , 

 its slenderer and more filiform antennpe, the larger size of the four
