CANARTAN COLEOPTKRA. 



slightly picescent elytra, and the very acutely conical last joint of its 

 palpi, this minute PhiJonthus is at first sight almost identical with 

 the Madeiran P. Jiliformis. When closely inspected, however, it will 

 be seen to differ in many respects from that species. Thus, its eyes 

 (although not more prominent) are considerably larger ; its head is, 

 if anything, somewhat convexer, and more free from punctures in the 

 centre ; its elytra are a little more coarsely punctured ; and its ab- 

 dominal segments are, each of them, more imj^ressed behind (and 

 therefore convexer in front), and also (particularly the basal ones) 

 very rugosely and densely punctured posteiiorly . Hitherto I have 

 observed it only in Teneriffe, where, however, I captured it in con- 

 siderable abundance — from amongst wet shingle at the edges of a 

 little stagnant pool at the extreme head of the Barranco Santo, close 

 to S*''' Cruz. And a single specimen (likewise TcnerifFan) is now 

 before me which was taken by Dr. Crotch. 



880. Philonthus xantholinoides, n. sp. 

 P. tenello similis, sed (si ex unico specimine immature adjudicare licet) 

 ahter coloratus (sc. minus niger, prothorace' fortassc etiam rufo- 

 ferrugineo) ; capite majore, quadratiore, basi rectius truncato, antice 

 distinctius canahculato (nee subtriangulai-iter impresso) et una cum 

 prothorace profundius utrinque punctato, oculis minoribus ; elytris 

 sensim majoribus ; abdominis segmentis singulis ad basin minus 

 grosse punctatis; an tennis paulo longioribus. — Long. corp. lin. vix 2.

Although I have but a single specimen, and that an immature one, 

 to judge from, nevertheless the present PhilontJius is so unmistakeably 

 distinct (even in some few of its structural details) from the P. tenellus 

 that I cannot omit it from this Catalogue. In its small size, narrow 

 outline, and the acute terminal joint of its palpi it is very similar to 

 that species ; but its head is larger and squarer (being more straightly 

 truncated behind), and, together with the prothorax, more deeply 

 punctured, its eyes are smaller, its elytra are a trifle more developed, 

 its abdominal segments are both less convex and less coarsely punc- 

 tured at theii- respective bases, and its antennae are longer. Its fore- 

 head, also, is more decidedly marked with a central channel in front, 

 but less triangularly impressed. The example described from (which 

 was taken by myself, in company with the last species, near S'"* Cruz 

 of Tenerifte) being immature, I cannot say much as to the differences 

 of colour ; bat I believe that the P. xantholinoides will be found to be 

 of a much paler hue, and perhaps to have its prothorax rufo-ferru- 

 ginous.
