This large and beautiful Dromius may be regarded as the Canarian 

 representative of the Madeiran D. insularis, — to which, although ex- 

 ceedingly distinct from it specifically, it is closely allied. Apart, 

 however, from the somewhat darker hue of its head and prothorax 

 (the former of which is less strigulose in the centre, whilst the latter 

 is more elongate and straighter behind), it differs from that insect 

 in its brighter surface, and convexer and more rounded elytra — 

 which have their striae less impressed, and their postmedial fascia 

 broader (extending in fact to the outer margin, which is itself also 

 usually more or less blackened or infuscated). It is apparently 

 very rare, or at any rate local, and confined (so far as I have ob- 

 served hitherto) to the sylvan regions on the north-eastern mountains 

 of Teneriffe, from the wood of Las Mercedes to Point Anaga. In 

 the former I took it, not uncommonly, from beneath damp loosened 

 bark, during June 1858 ; and, at the end of May of the following 

 year, I met with it in similar spots in the laurel-district above 

 Taganana. 



18. Dromius elliptipennis, n. sp. 



D. nitidus ; capite piceo, latiusculo, oculis magnis, prominentibus ; 

 prothorace nifo-testaceo, subquadrato postice angustiore, ad an- 

 gulos posticos late explanato ; elytris ellipticis, ad latera rotundatis, 

 testaceis, pone scutellum necnon per suturam obscure sed in fascia 

 communi media maxima dentata distincte nigro-fuscis ; antennis, 

 palpis pedibusque testaceis ; tarsis posticis longiusculis. — Long.

Habitat in sylvaticis excelsis Teneriffse, Gomerse et Hierro, raris- 

 simus. 



Until lately I had regarded this Dromius as a " var. /3 " (pecuKar 

 to the sylvan regions) of the D. sigma ; but the opinion (recently) of 

 Dr. Schaum that it is certainly distinct has induced me to examine 

 it with greater care, and I now believe with him that it cannot be 

 I'cferred to that species. It may be known readily from the sigma
