liver, fig. 17 ca.c, and, from fig. 15, we see that the membvaue which separates 

 this space from the peritoneal cavity passes partly internally to the kidneys and 

 partly outside them, so that it represents more than the peritoneum. Also, 

 from fig. 14, that it is not correct to say that the membrane referred to excludes 

 the kidneys from the peritoneal cavity, in which lie the genital glands, for the 

 posterior portion of the kidney lies distinctly vrithin this latter cavity. 



4. Descriptions of new Species of the Coleopterous Family 

 Erotylidce. By Rev. H. S. Gorham, F.Z.S. 



[Received November 11, 1889.] 

 (Plate LXI.) 



The following descriptions are to some extent supplementary to my 

 paper on the Erotylidae read before the Society in 1883 (see P. Z. S. 

 1883, p. 75). 



The types are either in my own collection or in that of Mr. E. 

 Armitage, R.A. ; a few of the specimens are also contained in the 

 Cambridge collection formed by the late Mr. Crotch, whose MS. 

 name I have retained for the first species here described ; it was, 

 however, placed in Episcapha, the specimen being hardly well enough 

 preserved for critical examination. 



1. Triplatoma varia, sp. nov. (Plate LXI. fig. 1.) 



Elongata, subparallela, nigra, rufo-maculata, subnitida ; vertice, 

 prothoraceis utrinque macula arcuata ; elytris fasciis tribus den- 

 tatis, prima per rammn cum basi conjuncta rufis ; corpora 

 subtus rvfo piceoque variegato, femoribus infra rufo-maculatis. 



Long. 17 millim. 



Hab. Malacca, Penang {coll. Crotch and E. Armitage). 



Head closely but distinctly punctured ; antennse with the third 

 joint not much enlarged at the tip, the fourth to the eighth joints 

 longer than broad. The thorax transverse, very finely and thickly 

 punctured, smooth and shining, the front angles a little prominent, 

 the sides almost straight, the front as wide as the base ; hind angles 

 rectangular. Elytra smooth, with fine serially punctured striae and 

 flat interstices, or very obsoletely subsulcate. The red markings 

 are a broad spot on vertex of the head, a mark somewhat like a 

 Hebrew, letter Caph on each side of the thorax, the open side out- 

 wards, one corner reaching the front angle, the other prolonged 

 towards the base. 



On the elytra are three irregular fasciae, much as in T. gestroi. 

 Bedel, but less dentate ; the first with a ramus to the base forms a 

 sort of ring enclosing the shoulder, except on the costal side, the 

 second arcuate, the third is near the apex ; none of them approach 

 nearer the suture than the first stria. The epipleuree have a spot 

 at the base, and one on each side of the metasternum and of each 

 ventral segment are red. 



T. varia is allied to, but amply distinct from, T. gestroi ; it is 

 smaller, smoother, the thorax is shorter, but it will fall into the
