(Subfam. Tachyporides.) 



Genus Hypocyptus. 



Mannerheim, Brachel. 58 [script. Hypocyphtus] (1831). 



Hypocyptus reductus, n. sp. 



H. acuminato-obovatus, convexus, niger, nitidus, pubescens ; pro- 

 thorace ad latera angustissime diluto ; elytris valde abbreviatis, 

 singulatim oblique truncatis ; antennis pedibusque piceo-testaceis, 

 illarum articulo ultimo longitudine reducto.

H. obovate, being rounded in front and acuminated behind, 

 convex, black, shining, scarcely perceptibly punctulated (even 

 beneath the microscope), and sparingly clothed with a fine, de- 

 cumbent, cinereous pile. Head transverse, and somewhat acu- 

 minated between the eyes. Prothorax and elytra of the same 

 breadth at their point of junction : the former with its hinder 

 angles acute and produced, and with its extreme lateral edge 

 narrowly diluted in hue ; the latter very short, and each of them 

 obliquely truncated behind. Antenna but very slightly incras- 

 sated at their apex, and with their ultimate joint shorter and 

 rather more obtuse than in the ordinary Hypocypti, rufo-testa- 

 ceous at the base ; their apical portion, as well as the femora 

 and tibia, darker, or more piceous. Tarsi pale testaceous. 



A single example of the present Hypocyptus was taken by 

 myself from beneath a piece of board which was lying on the 

 damp earth in the garden of the American Consulate, in the 

 very centre of Funchal. From the circumstances of its capture, 

 one might have imagined that it was in all probability a chance 

 specimen which had been accidentally imported into the island, 

 did not its decided specific divergence from the European Hypo- 

 cypti tend to an opposite conclusion. Apart from minor features, 

 the concolorous apex of its abdomen, in conjunction with the 

 structure of its antennae (which are somewhat slenderer and less 

 clubbed than those of its more northern allies, and have their 

 terminal joint shorter and more obtuse), will at once serve to 

 characterize it. 



Genus Mycetoporus. 



Mannerheim, Brachel. 73 (1831). 



Mycetoporus Johnsoni, n. sp. 



M. rufo-testaceus, nitidus ; pectore abdomineque (ano plus minus 

 ferrugineo excepto) obscurioribus ; oculis parvis ; prothoracis
