193.— Hydrochus parallelos. n. sp. 



Length Tj Hues. 

 Of a dark bronzy green and opaque. Head punctured, with 

 a deep stria on each side between the eyes extending from the 

 occiput to the suture of the epistome, and with a shorter one in 

 the middle not reaching the occiput. Thorax coarsely punctured, 

 with the surface covered with several large shallow indistinct 

 foveas. Elytra more nitid than the thorax, with the suture broad 

 and smooth, and on each side of it ten strias, placed close together 

 and filled with large punctures, and with the alternate interstices 

 slightly elevated. The legs are reddish, the knees black. 



194. HYDRiENA LDRIDIPENNtS. n. Sp. 



Length f of a line. 

 Elongate-ovate, subconvex, and closely punctured. Head 

 black. Thorax pale at the sides, brown in the middle, not 

 broader than the length, with all the angles acute, and with the 

 sides bulged out almost angularly in the middle. Elytra of a 

 lurid brown closely covered with punctate strias. 



195. — Cyclonotum Mastersii. n. sp. 



Length 2 1 lines. 

 Oval, convex, black, subnitid, and entirely covered with fine 

 punctures. The thorax is narrowly tinged with red on the lateral 

 margins. The elytra have a narrow stria on each side of the 

 suture. The under side is black and smooth. The tarsi and 

 palpi are red. 



196. — Cyclonotqm pygmj;um. n. sp. 

 Length 1 line. 

 With the exception of the great difference in size, the greater 

 proportionate width of the elytra behind, and the more oval oblong 

 form, there is very little difference between this and the last 

 described species. It has the same uniform black colour, the 

 same kind of puncturation, and the same subsutural strias on the 

 elytra.
