Numerous specimens of this were taken by Mr. H. L. 

 Andrewes by sweeping in the Auchterlony Valley (3500- 

 5000 ft.) in December, also by beating round small patcliea 

 of jungle in hollows of open downs at Naduvatum (6000- 

 6500 ft.). It is very like 0. Jucundus, but smaller, more 

 oval, and more convex. The pattern and arrangement of the 

 pnbescence are the same, but the hairs are shorter and less 

 uniform and lie closer together, the posthumeral band and 

 apical patch of light hairs are more sharply defined, and the 

 hairs occupying the remaining surface of the elytra much 

 shorter and darker. The antennae are light red, the last joint 

 very large, flat, and completely circular in the male, and the 

 preceding joint very small. In the female the penultimate 

 joint is nearly half the diameter of the last. The last visible 

 (fiftii) ventral segment of the male is broadly depressed, and 

 the hind margin armed with a spine on each side of the 

 depression. 



Orphinus minor, sp. n. 



Fusco-niger, antennis pedibusque rufescentibus ; ovatus, convexus, 

 griseo-pubescens, supra undique profunde sat grosse et crebre 

 punctatus, pronoti lobe postico brevi, rotundato. 



Long. 2 mm. 



Hah. Bombay: Belgaum. 



A number of specimens were taken by Mr. H. E, Andrewes, 

 by whom it has been presented to tlie British Museum, 

 together with the two preceding species. It was found in 

 company with O.jucundus in sweeping grass at the end of 

 the rains (November and December), but not nearly so plenti- 

 fully as the other species. 



It is like 0. affinis, Reitt., without spots or bands of 

 pio-ment or pubescence, and also without the reddish extre- 

 mities of the elytra of that species. It is also smaller, less 

 elongate, and more convex, with the prothorax relatively 

 much longer and more rounded in front. The posterior lobe 

 is shorter and more broadly rounded. The puncturation and 

 clothing are almost exactly as in 0. affinis. 



Orphinus tahitha, sp. n. 



Totus niger, sat nitidus, tarsis antennisque solum piceis ; breviter 

 ovatus, valde convexus, baud longe griseo-pubescens, prothoracis 

 lateribus, fasciis elytrorum tribus transversis suturaque anguste 

 pilis longioribus et densioribus ornatis, fascia prima basali, secunda 

 antemediana tertiaque anteapicab, corpore supra profunde eat 

 crebre punctato, pronoto postice valde lobato. 



Long. 2-5-3 mm.
