CANARIAN COLEOPTERA. 529 



''Body covered with squamiform hairs. Head not broader than the 

 prothorax and a little longer than broad, ronnded behind and nar- 

 rowed in front (the front being produced into a sliort process), lon- 

 gitudinally divided by a feeble channel ; the forehead rather flat, 

 and impressed with two fovese. Eyes very prominent. Antennoi 

 implanted at the sides of the frontal process, and 11-jointed; the 

 first tAvo joints thicker than the following one (the 1st being sub- 

 cylindrical, and the 2nd somewhat rounded), the 3rd to the 7th 

 equal and subglobular, the last four different according to the sex, 

 — in the male aU of them being thickened (the 8th considerably 

 larger than the 7th, the 9th also larger than the 7th but smaller 

 than the 8th, the 10th a little larger than the 8th, the 11th much 

 incrassated, twice as long as the 10th, and rounded, with a some- 

 what oblique apex); whilst in ih.e female the last two joints only 

 are thickened (the 8th being even a trifle smaller than the 7th and 

 9th, which are of equal size), but a little smaller than in the male. 

 Maxillary paljii 4 (?)-jointed, — the basal joint (if existing) mi- 

 nute and not visible without dissection, the second strongly bent 

 (being almost elbowed behind the middle) and slightly thickened 

 at the apex, the third greatly dilated (more so on its inner than 

 its outer side) and almost semilunar (being rounded at the base 

 and nearly straight along its anterior edge — the outer horn being 

 produced into a long setiform appendage, whilst on the inner horn 

 the last joint is implanted), and the fourth of the same size as the 

 preceding one but forming a transverse cone, and equally fur- 

 nished with a lateral setiform appendage. Prothorax not longer 

 than broad, with a round and large fovea in the middle behind, 

 and a deep longitudinal impression on either side. Elytra longer 

 than the prothorax, rounded at the shoulders and dilated towards 

 their apex, transversely impressed along their hinder edge, and 

 more thickly covered in this impression (or groove) with squami- 

 form hairs ; with an entire stria (on each) alongside the suture, 

 and another in the middle which is more deeply impressed at the 

 base. Ahdomen with four segments uncovered; the first three 

 have a thick margin, and the second is densely clothed with squa- 

 miform hairs at its base. Legs slender ; tihue a little bent ; tarsi 

 narrow and short (the four hinder ones being four times shorter 

 than the tibiae), and all of them terminated by two equal and mi- 

 nute claws." 



794. " Enoptostomus Wollastoni, n. sp. 



"E. rufo-testaceus, nitidus, subdepressus. — Long. corp. lin. |." 

 Habitat in Teneriffa et Gomera, sub lapidibus rarissimus. 

 Apparently both rare and local. The only examples (about twenty 

 in number) which I have seen (except one which was found by Dr. 

 Crotch in Gomera) were captured by myself close to S'^'' Cruz, in Tcne- 

 riffe — from beneath small stones, under some fig-trees, at a low ele- 

 vation in (and on the southern side of) the Barranco do Passo Alto.
