224 Mr. Waterhouse on new species of Coleoptera. 



This species is closely allied to the preceding, but differs as 

 follows : — Clypeus very short, very strongly and densely punc- 

 tured, the punctures touching one another. Forehead rather 

 more deeply punctured. Thorax (viewed from above) gradually 

 narrowed in front, the sides gently arcuate, the punctuation is 

 rather stronger than in A. nigrescens, very close, the intervals 

 between the punctures equal to the diameter of the punctures, 

 the sides (viewed laterally) are less rounded posteriorly, the 

 anterior angles (although slightly acute) are not prominent and 

 are not flattened. The punctuation of the scutellum is not very 

 close, finer than in A. nigrescens, and equally distributed over 

 the surface. The punctuation of the elytra is the same, but of 

 the five lateral rows of strong punctures, the pair proceeding 

 from the shoulder are separated by a small space from the other 

 three, and this space is punctured as the rest of the elytra. The 

 punctuation of the sides of the metasternum is strong, and the 

 spaces between the punctures are rather less than the diameter 

 of the punctures, whereas in A. nigrescens the punctures are 

 smaller and almost contiguous to each other. Pygidium with a 

 short raised mesial line. 



Hab. Andaman Island (R. Meldola, Esq.). Brit. Mus. 



In the Museum collection is a specimen named cerea, Bl., 

 which differs from both the preceding in having the thorax 

 (when viewed from above) rounded at the sides, and Avhen 

 viewed laterally very much rounded (almost from the anterior 

 angle), the posterior angle not defined, and the scutellum is 

 almost smooth, &c. 



Apogonia rauca, Fabr. 



The following notes from the type specimen of this species 

 in the Banksian collection may be useful. Clypeus deeply 

 punctured, the interspaces a little less than the diameter of the 

 punctures ; forehead rather less deeply punctured and the dis- 

 tances between the punctures average about 1^ times the 

 diameter of the punctures, the sides are very much rounded. 

 The scutellum has two lines of punctiires on each side. The 

 pimctuatiou of the elytra is very deep and coarse, the intervals 

 about half the diameter of the punctures, the second dorsal 

 costa is very narrow and somewhat obsolete posteriorly, the 

 frequently found third costa is not discernible, as the punctures 

 on this part of the elytra are in lines, between the extreme 

 margin and the most lateral line of punctures there are a few 

 large punctures below the shoulders. The sides of the meta-
