short and inconspicuous apical spines of the elytra, the scarcely 

 at all spinose femora and apparently rather more plentiful or 

 coarser pubescence. 



Romaleum White. 



The moderately numerous species of Romaleum are well dis- 

 tinguished from any other of the Elaphidion section of the Ce- 

 rambyci, by their large size, very stout and more or less convex form, 

 great sexual differences in the prothorax and broader and more 

 posteriorly narrowed met-episterna. The genus is a distinctly valid 

 one. Besides simplicicolle Hald., and procerum Lee., the latter 

 being plainly distinct from the former and not a variety, much 

 less a synonym as pronounced by Dr. Horn the genus will include 

 atomarium Drury, ntfulum Hald., seminitidum Horn and taniatum 

 Lee. ; the species niveitectum, of Schaeffer, may also be included for 

 the present, although it differs considerably in thoracic characters. 

 The three following species are allied to atomarium and rufulum: 



Romaleum thoracicum n. sp. Stout, convex, very dark brown to 

 blackish throughout. Female with the antennae slender, flattened 

 beyond the fourth joint, extending to about apical fourth of the elytra, 

 strongly punctured and coarsely, pallidly pubescent basally, becoming 

 more finely so on the sixth and thence very finely and densely to the tip, 

 with the more densely pubescent areas conspicuous, the spines small, 

 gradually decreasing, the joints beyond the fourth bispinose at apex, fourth 

 two-thirds as long as the third and less than four-fifths as long as the fifth ; 

 prothorax subglobular, about a fourth wider than long, evenly and strongly 

 rounded on the sides throughout, the apex distinctly narrower than the 

 base; surface coarsely, not very deeply, confluently and confusedly punc- 

 tured, having only moderately close, even, short decumbent hairs and very 

 numerous longer erect hairs, having also a tumid callus two-fifths from 

 the apex at outer fourth and an elongate-oval, smooth and feebly convex 

 area on the median line behind the centre; elytra two and a third times 

 longer than wide, a fourth wider than the prothorax, tapering rather 

 strongly from base to apex, the apices broadly sinuate between the rather 

 long and slender, equal spines; surface even, the short yellowish vestiture 

 closely decumbent and aggregated into irregularly condensed areas, 

 also with numerous short stiff suberect hairs throughout, not so long as 

 those of the prothorax, the punctures strong, only moderately large, deep, 

 perforate, separated by two to four times their diameters basally, sensibly 

 smaller but distinct distally; femora wholly unarmed. Male similar 

 but larger, the antennae two-thirds longer than the body, gradually 

 notably stout basally, densely sculptured, the fourth and fifth joints 

 equal; prothorax narrower and less transverse than in atomarium, 

 distinctly narrower than the base of the elytra, with nearly similar fine 

 dense sculpture and callous spots, but less densely, more finely and more
