256 CANARIAN COLEOPTERA. 



outer edge rounded and minutely serrated, as in the Xyloieri. Never- 

 theless, in its very much smaller size and concolorous hue, as well as 

 in its much longer prothorax, which is considerably more produced 

 in front, and its total freedom from a visible scutellum, it recedes from 

 Xyloterus, and perhaps might almost seem to constitute the ty^DO of 

 an allied Group. In the absence, however, of further material, and 

 considering the essential points which it possesses in common with 

 Xyloterus, I prefer treating it as an exponent of that genus. The 

 only other genera of the Tomicidce which have, so far as I am aware, 

 a 4-jointed funiculus are Cryphalus and Leiparthrwn, — from both of 

 which it differs far more, in its primary details, than it does from 

 Xyloterus. 



413. Xyloterus longicollis, n. sp. 

 X. breviter cylindricus, crassiusculus, rufo-ferrugineus, subnitidus, 

 pilis erectis subcinereis sat parce obsitus ; prothorace elongato, 

 asperato (etiam postice vix punctate) ; clytris paulo rugulosis et 

 leviter seriatim punctatis, ad apicem obtusis sed integris ; antennis 

 pedibusque clarioribus ; tibiis latis, extus minute spinuloso-serratis.

Habitat Fuerteventuram ; sub stercore camelino ad Eio Palmas d. 

 6. Apr. A.D. 1859 exemplar unicum collegi. 



The unique specimen from which the above diagnosis has been com- 

 piled was captui-ed by myself, on the 6th of April 1859, together with 

 numerous other insects, from beneath the refuse of a camels' stable in 

 the Eio Palmas of Fuerteventura. It is probable, however, that its 

 presence in a position so anomalous for a member of this famUy was 

 merely accidental. 



Genus 174. CRYPHALUS.

 Habitat Teneriffam, in caulibus emortuis lignoque antique degens. 



This very minute wood-borer, which is not uncommon in Madeira, 

 occurs also at the Canaries. Hitherto, however, I have detected it 

 only in TenerifPe, namely (sparingly) near S''^ Cruz, and (more abun- 

 dantly) above the Puerto of Orotava ; in the latter of which localities 

 I captured it, during May 1858, from out of the dead stalks of a Gera- 

 nium in the garden of the " Dehesa." From its diminutive size it is 

 extremely hkely to escape observation ; but there is reason to believe 

 that its geographical range is by no means restricted to these imme-
