Omojphron Brettinghamce. 



O. ovato-rotundatum, nitidum, testaceum ; capite^ prothoracis disco, ely- 

 trisque (marginibus exceptis) viridi-seneis. 



Hab. India (Dacca). 



Shortly ovate or nearly orbicular, moderately convex, very smooth and 

 shining ; head sparingly punctured, brassy-green ; labrum, epistome, and 

 small triangular spot above the latter brownish-testaceous ; prothorax 

 finely and remotely punctured, and with the elytra rich brassy-gTeen, 

 bordered externally with testaceous, — the border much wider on the 

 latter, which are also very finely punctured in rather distant rows; 

 eyes and tips of the mandibles dark brown ; antennae, palpi, and legs 

 pale testaceous ; body beneath with the sterna pitchy, the abdomen 

 deep testaceous. Length 2 lines. 



For the possession of this and many other Coleoptera from the 

 same locality, I am indebted to Dr. Ernest Adams of University 

 College, the author (;inter alia) of some exceedingly interesting 

 and learned papers on the " Yemacular names of Insects," in the 

 Transactions of the Philological Society, who received them from 

 India*, where they were collected by Mrs. Brettingham (to whom I 

 have dedicated the exquisite little Omophron just described) in the 

 compound attached to the quarters of Charles Brettingham, Esq., in 

 medical charge of the Kamroop Regiment of N'ative Infantry sta- 

 tioned at Dacca. They comprised above seventy species, belonging 

 to nearly as many genera. Of these there were only six or seven 

 that were not represented in Europe, viz. Adoretus, Heteronychus, 

 Anisotelus, Macratria, a Mtidulid, and two, or perhaps three, obscure 

 Heteromerous genera, which I have not been able to refer to any 

 hitherto published. Except that there were very few Staphylinidae, 

 they were mostly such forms as would be found in this country in 

 the debris of a flood ; and it is, therefore, most likely that they 

 were collected in the rainy season. Dacca is nearly in the latitude 

 of Calcutta, lies very low, and as it is subject to inundations from 

 the Ganges, it is probable that it affords a larger proportion of 

 European forms than would have been the case in a drier or more 

 elevated district. So little is really known of the Entomology 



* Upwards of a thousand specimens, some nearly an inch long, although gene- 

 rally much smaller, enclosed in two large-sized pill-boxes, were transmitted by 

 post in the ordinary way in a single letter. A wine cork hollowed out in the 

 middle, and a Uttle trimmed at the sides, would be an excellent, and at all times 

 available substitute for a box.
