brown, with the apex and some obscure spots greyish ; body- 

 beneath and legs black or piceous ; eyes piceous ; pronotum^ 

 distinctly transversely wrinkled ; scutellum reaching apex of 

 clavus, somewhat obliquely depressed at basal area, punctate, 

 wrinkled, the apical area longitudinally ridged; corium 

 somewhat thickly punctate ; face strongly compressed be- 

 hind eyes ; spinules to the posterior tibiae long and prominent. 



Long. 9 mm. 



Hab. Borneo ; Kuching (Hewitt, Brit. Mus.). 



Allied to the Indian species H. orientalis, Walk., from 

 which it differs by the considerably- more acute apex of the 

 face, more strongly wrinkled pronotum, &c. 



Vangama ? tuberculata. 

 Prolejyta? tuhei-cidata, Walk. List Horn., Suppl. p. 315 (1858). 



This species, described by Walker in the Fulgoridae, really 

 belongs to the Jassidse, and can apparently be included in 

 my genus Vangama (Faun. B. I., Rhynch. iv. p. 260).

In last month's ' Annals ' I published a paper proving that 

 Stromatoporoids and Eozoon were Foraminifera. It was 

 there pointed out that they had a calcareous chambered 

 skeleton, with the walls of the cliambers penetrated by tubuli, 

 and that there were present in the canals hoops and rings 

 siniihir to those of recent Perforate Foraminifera. Further, 

 I figured a coiled Foraminiferan shell in one of the chambers 

 of Eozoon, So far my evidence was not much in advance of 

 that already given by Dawson and Carpenter. 1 had done 

 nothing to unravel the bewildering complexity and confusion 

 presented by the skeletal arrangement nor to ex[)lain how
