334 Appendix to the Proceedings 



lunar depression, which is well marked ; the base is very slightly 

 but broadly emarginate ; in front of the emargination is a sinuate 

 transverse depression, on each side of which is a fovea; the an- 

 terior angles are broadly rounded, the posterior are obtuse. 

 Scutellum ferrugineo-fuscous, rugosely impressed. Elytra with 

 a greater virescence than the head and thorax, very faintly punc- 

 tate; striate, but without punctation in the striae; the inter- 

 stices slightly convex; two or three slight foveas on the outer 

 side of the second stria, one about a third from the base, the 

 next about a third from the apex, and the last about a sixth from 

 the apex; a number of pits are placed at irregular distances 

 along the marginal space. Under side fuscous, paler than above, 

 and not virescent ; the middle and the abdomen are not punc- 

 tate, but the side-pieces (episterna and epimera) are all faintly 

 and irregularly punctate. The legs are pale testaceous. 



I have named this species after Herr Dohrn of Stettin, an 

 entomologist of world-wide reputation, whose great attain ments 

 as a man of science are only equalled by his genial and endearing 

 qualities as a friend. 



2. D. Smithii, mihi. 



Prsecedenti similis, sed major ; niger et haud virescens ; ca- 

 pite linea transversa antice multo minus profunda ; thorace 

 disco impunctato, angulis posticis minus obtusis, ad mucro- 

 nem fere rectis ; elytris interstitiis impunctatis, striis profun- 

 dioribus quam in D. Dohrnii ; subtus vix punctatus ; cseteris 

 ut in D. Dohrnii.

Closely allied to the preceding, but differs from it in the fol- 

 lowing particulars. It is black instead of virescent fuscous. 

 The head is wholly impunctate ; the angular depressions in front 

 are shallow, and united by a faint transverse line instead of a 

 deep groove, and the epistome has scarcely any depression. The 

 thorax is impunctate on the disk ; the dorsal line is scarcely 

 punctate, and it reaches wholly to the front, the posterior angles 

 are less obtuse than in D. Dohrnii, and somewhat sinuate, so as at 

 the very point to be almost right-angled for a short space. The 

 elytra are more deeply striate, and the interstices more convex 

 and impunctate. The under side has scarcely any punctation 

 at ail, either on the sides or middle. In other respects the same 

 description will apply to the two species. 



I have named this species after my friend Mr. Frederick Smith 

 of the British Museum, whose kindness places the extensive infor- 

 mation he possesses at the disposal of all who desire to profit by it.
