Sp. 9. castanopterus. Piceo-niger, elytris, antennis, pedibusque saturate cas- 

 tanets. (Long. corp. 1^ lin.)

Rather less than the last : head and thorax deep, slightly glossy, pitchy-black ; 

 the former with two parallel frontal sulci ; the latter convex, with a faint dorsal 

 line, and a small impunctate fovea on each side at the base : elytra deep im- 

 maculate chesnut, striated, the striae faintly punctate and dusky : abdomen 

 beneath pitchy-ferruginous : legs and antennae deep chesnut. 



I have one specimen of this insect, which I caught in the neigh- 

 bourhood of London some years back. 



Genus LXXI. — Lopha, Megerle. 



Palpi rather short ; external maxillary with the second and third joints of nearly 

 equal length, the latter rather suddenly clavate and very pilose, the terminal 

 joint very short, sub truncate ; labial with the terminal joint rather elongate 

 and acute, the preceding abruptly clavate: lab rum short, transverse, entire: 

 mandibles rather slender, elongate, acute: mentum with the anterior edge 

 emarginate, the emargination with an acute central lobe. Antennas with the 

 two basal joints naked, the rest pubescent; the third and fifth of equal length, 

 and longer than the fourth: thorax very globose anteriorly, depressed and 

 attenuated posteriorly, and apparently remote from the elytra; the latter 

 rather convex, the back depressed : legs rather slender : anterior tarsi of the 

 males with the basal joint dilated. 



The great convexity of the anterior portion of the thorax, and 

 the attenuation of the posterior (which gives it the appearance of 

 being somewhat remote from the elytra), well distinguish this 

 genus from the rest of the family: to which may be added the 

 greater convexity and glossiness of the body and slenderness of the 

 legs. A few of the last species greatly resemble the insects of the 

 genus Tachypus, by having the thorax more depressed anteriorly, 

 &c. as hereafter mentioned. 



Sp. 1. pcecila. Nigro-cosridescens , nitida, antennis pedibusque testaceis, elytris 

 testaceis, fasciis duabus posticis fusco-brunneis. (Long. corp. 1^ — if lin.)

A beautiful species ; of a deep glossy blue-black : head with two deep anteriorly 

 approximating sulci in front: thorax above convex, glossy, smooth, black- 

 blue, with a faint dorsal channel, and a transverse punctate impression at the
