fuscus, lateribus (episternis et epimeris) leviter et irregulariter 

 piinctatis, medio et abdomine impunctatis ; pedibus pallidis.

Above fuscous with a virescent tinge. Head polished and 

 sparingly punctate behind the eyes^ the rest impunctate, or 

 nearly so ; a deep angular fovea on each side near the inner cor- 

 ner of the eyes, united by a deep impunctate transverse line^ in 

 front of which the epistome is marked by a broad, transverse, 

 somewhat rugose depression ; antennae, clypeus, palpi, and parts 

 of the mouth more or less ferruginous ; clypeus with a row of 

 depressions in front, from each of which springs a hair. Thorax 

 rather convex, with a broad well-defined depression along the 

 margins and angles, broadest at the posterior angles, and bordered 

 all round with a slight raised edging ; slightly punctate on the 

 disk, more deeply so on the depressed margins ; the dorsal line is 

 feebly punctate-striate, and reaches only to the anterior semi- 

 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 fovece 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 attainments 

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

 qualities as a friend. 



2. D. Smithii, mihi. 



Praecedenti similis, sed major ; niger et hand 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 ; caeteris 

 ut in D. Dohrnii.
