reception of the present species it has been referred to that genus. The seven 

 specimens, under examination, appear to belong to but one species, although no 

 two are alike in their size, colour, and markings. The type is 5 mm. in length, 

 of a dull reddish-brown colour, with two elongated dark spots on the pronotum 

 and some vague infuseations on the elytra ; it is rather densely clothed with ashen 

 ]:»ubescence, becoming denser on the scutellum, and on an apical triangle on the 

 elytra; the triangle commences on the suture just beyond the middle, and is 

 dilated so as to cover the entire apex : it is distinct on all the specimens and 

 accentuated by a dark oblique line on each elytron immediately before it, although 

 on two. specimens the dark lines are very faint. The largest specimen is some- 

 what paler than the type, and has four spots on the prothorax (the lateral ones 

 very feeble) and one on each shoulder, in addition to the postmedian ones; 

 three specimens are darker, Avith the dark markings on the prothorax ill-defined, 

 a'nd the elytral markings connected so as to appear like a reversed M. The 

 smallest specimen is entirely pale, the oblique lines before the apical triangle 

 being represented by semi-nude spaces that are scarcely perceptibly infuscated. 

 On some specimens the club is hardly darker than the rest of the antennae. The 

 sides of the prothorax are usually widest almost at the base, but on several of 

 the smaller ones the greatest width is median ; the emargination of the apex is 

 an even incurvature, not a three-sided incision as on others of the genus; there 

 are vagvie remnants of striation on the elytra. 



GY]\INOCYCHRAMUS nov. gen. 



Head wide between ej^es ; clypeus narrow, hind suture obliterated ; labrum 

 rather large, deeply bilobed. Eyes fairly large, lateral, prominent, moderately 

 faceted. Mandibles strong, dentate near apex. Antennae thin; club large, 

 compact, almost circular, three-jointed. Palpi small, approximate at base. 

 ProtJiorax wide, sides finely margined and strongly rounded. Scutellum large, 

 semicircular. Elytra covering abdomen except part of pygidium. Prosternum 

 in middle about half the length of pronotum, ridged along middle in front, 

 produced as an equilateral triangle behind coxae, the tip of the triangle marking 

 the summit of an acute ridge ; coxal cavities large, transverse, each closed by a 

 narrow strip. Metasternum elongate ; axillary piece on each side rather wide 

 and traceable, but very narrow, to beyond the middle. Abdoynen with first 

 . segment, along middle, longer than fifth, the others short and equal. Legs rather 

 short and stout; femora grooved and edentate; tibige with two spines at inner 

 apex, the front ones with a strong spur at outer apex; tarsi with three basal 

 joints, wide and densely clothed on under surface, fourth small, fifth long 

 and thin. 



Allied to Cycliramus, but labrum more conspicuously notched, intercoxal 

 process of prosternum triangular posteriorly, and upper surface polished and 

 glabrous; the notch in the labrum is so deep that, from behind, it appears to 

 extend to the clypeus; there is a groove in front of each eye for the reception 

 of the basal joints of antennae.
