low power in the microscope, I soon perceived that the punctuation of the thorax was 

 much more dense in the insect I call O. nigro-fusca. 



Found in the dSbris left upon removing a stack of faggots in Bishop's Wood, near 

 Hampstead. 



HOMALOTA PLUMBEA. 



H. Plumheo-nigra, opaca, griseo -pubescent, creherrime suhtilissime punctata ; antennia 

 ftiscis, peclibus fusco-testaceis ; thorace mbquadrato coleopteris multo angus- 

 tiore ; abdomine nilidiusculo. Long. lin. 



This species should he placed in Kraatz's second section, near to the Tachyusiform 

 species, such as Horaalota labilis, &c., in which the elytra are ample, distinctly 

 broader than the thorax. It reminds one of H. incana, JErichs., agreeing pretty 

 nearly in size, form, and colouring with that insect, but it is much more thickly and 

 finely punctured, and the antennae are longer, and none of the joints are decidedly 

 transverse ; the legs, moreover, are paler. Head rather narrower than the thorax, 

 convex and rounded, but with the eyes slightly prominent, and the parts of the mouth 

 rather produced, the surface, like that of the thorax and elytra, of a somewhat dull 

 and silky appearance, owing to the thickness and fineness of the puncturing, combined 

 with a tolerable dense and fine ash-culoured pubescence; palpi and antennae dusky, 

 the latter sometimes, with the base, dirty testaceous ; they increase very slightly in 

 thickness towards the apex ; the first three joints considerably elongated and very 

 nearly equal; of the following joints the first are rather longer than broad, and the 

 penultimate quadrate ; the terminal joint nearly equal in length to the two preceding 

 taken together. Thorax subquadrate, slightly emarginate in front; the sides pre- 

 senting a very gentle sigmoid curve, being a little dilated and rounded towards the 

 fore part and slightly contracted behind; posterior margin rounded, posterior angles 

 obtusely rounded anterior angles rather acute; upper surface moderately convex, 

 and with a somewhat large and shallow depression behind. Elytra ample, fully one- 

 fourth longer than the thorax, and nearly twice as broad. Abdomen growing rather 

 broader towards the hinder part, very thickly and finely punctured throughout. Legs 

 testaceous ; the femora and tibiae more or less suffused with brown. I can perceive no 

 diff'erences indicative of sexes in the specimens before me. 



Found by Dr. Power, at Seaford, near Newhaven. 



HoMALOTA IMBECILLA. 



H. Linearis, subdepressa, subtiliter pubescens, nigra, nitidiuscula, antennis pedibusque 

 fuscescentibus, ano elytrisque testaceis, his basi fuscis ; thorace iransversim 

 snbqnadrato ; abdomine supra omnium creb re punctata. Long. lin. 



Head very little narrower than the thorax, rounded and moderately convex, very 

 finely and rather thickly punctured ; antennae, if bent back, reaching about to the apex 

 of the elytra ; slender and with no perceptible increase in thickness towards the apex ; 

 the penultimate joints as long as broad ; the middle joints longer than broad ; the 

 terminal joint nearly as long as the two preceding joints taken together; palpi fuscous, 

 paler at the base. Thorax subquadrate, slightly broader than long, straight in front, 

 very gently rounded at the sides, and more distinctly rounded behind; above gently 

 convex, very finely and thickly punctured, and with a shallow fovea behind. Elytra 

 scarcely longer and very little broader than the tliorax, and very thickly and rather
