86 MR. M. JACOBY ON THE [Feb. 1, 



thorax finely punctured ; elytra more distinctly and closely punctate, 

 the interstices slightly rugose. 



Length 1 line. 



Head impunctate, the frontal tubercles distinctly raised. Antennse 

 nearly as long as the bod)', rather robust, the second joint nearly as 

 stout as the first, but shorter ; the three following joints more 

 slender, of equal length, the following slightly thicker. Thorax 

 transverse, the anterior angles oblique, notched before the middle, 

 the sides straight, slightly converging outwards ; the surface finely 

 and rather closely punctured. Elytra with a shallow depression below 

 the base, somewhat closely and rugosely punctured, the punctuation 

 visible to the apices ; legs short and robust. 



Balangoda. 



J. proxima is extremely closel)- allied to A. sordida, Baly, from 

 Japan, and may possibly be identical with that species ; but the 

 depression of the elytra below the base in the Ceylon specimens does 

 not permit me to refer them to that species, as I cannot see a similar 

 depression in A. sordida, of which I possess several specimens. The 

 antennae in the present insect seem to vary rather in colour, and in 

 one of the specimens, which I look upon as a variety, having been 

 taken together with the others, the third and the fifth joints of the 

 antennae are fulvous, the others black ; in this specimen the elytral 

 depression is also much more marked (the base being slightly raised) 

 than in the others. 



Aphthona vicina, sp. nov. 



Ovate, convex ; black ; the third and one or two following joints of 

 the antennse flavous ; thorax finely and remotely punctured ; elytra 

 more distinctly and closely semipunctate-striate. 



Length ^ line. 



One half smaller than A. proxima, the thorax much less transverse, 

 finely granulate, and the punctuation much more distant; the elytra 

 without any basal depression, very closely punctured ; the legs 

 entirely black, A. '/iip-nYa, Motsch., is described as " fere glabra " 

 with pale legs. A. obscurata, Rlotsch., is much larger, also described 

 as glabrous with testaceous tibiae and tarsi. In the present insect 

 the two first joints of the antennse as well as the terminal ones are 

 black, the intermediate joints more or less flavous. 



Dikoya. 



Aphthona dorsalis, Motsch. 



The description of the author, "Glabra, rufa, capite, thorace elytris- 

 que dorso nigris, corpore subtus subinfuscata," agrees very nearly 

 with two specimens before me. The antennse (the terminal joint 

 excepted) and the legs are, however, testaceous, and the posterior 

 femora have their posterior portion black ; this is not mentioned by 

 Motschulsky. There are also very fine punctures visible at the elytra, 

 when examined under a strong lens. It is therefore doubtful whether 

 I am rightly referring these specimens to the present species. 



Obtained at the Horton Plains.
