2. Tarphius angustulus, n. sp. 



T. angustus, rufo-piceus (vel piceo-ferrugineus), fere calvus (oculo 

 fortissime armato minute et parce fulvo-cinereo pubescens) ; pro- 

 thorace elongato, postice gradatim et leviter angustiore, ad latera 

 oblique subrecto, granulis maximis depressis obsito ; elytris paral- 

 lelis, minus sculpturatis, nee nodosis nee carinatis, concolovibus ; 

 antennis pedibusque vix clarioribus.

T. small and narrow, rufo-piceous or piceo-ferruginous, al- 

 most free from scales and seta?, though, under a high magnifying 

 power, sparingly studded with an exceedingly short cinereous or 

 fulvo-cinereous pubescence. Prothorax elongate, being widest 

 anteriorly (where it is rather broader than the elytra), but gra- 

 dually and regularly (but not very greatly) narrowed behind ; 

 with the front angles much porrected and acute, and therefore 

 with the emargination deep ; broadly flattened at the sides, 

 especially in front, but- convex on the disk, and with an im- 

 pressed transverse line just before the extreme base ; beset with 

 excessively large and depressed granules. Elytra with the sides 

 quite parallel; very lightly sculptured (particularly behind), and 

 altogether free from both nodules and ridges ; also concolorous, 

 there being no indication of paler blotches. Antenna and legs 

 of a slightly clearer hue. 



This is one of the most distinct of all the Tarphii which have 

 yet been detected, — its small size (for it is scarcely, if at all, larger 

 than the T. Lowei) and narrow outline, combined with its rufo- 

 ferruginous hue, its elongate prothorax (which is obliquely 

 straight at the sides, and regularly narrowed posteriorly), its 

 very lightly sculptured, parallel, concolorous elytra, and its 

 almost total freedom (except under a high magnifying power) 

 from pubescence or setse giving it a character which it is im- 

 possible to mistake. In spite of its diminutive bulk and com- 

 paratively unroughened surface, I am inclined to think that it 

 has perhaps a greater affinity with the T. parallelus than with 

 any other species hitherto described. 



The T. angustulus is also due to the researches of Senhor 

 Moniz, who lately discovered three or four examples of it in 

 the chestnut-woods at the Mount, above Funchal ; one of which 

 he has presented to the British Museum collection. This addi-
