much and suddenly wider than the prothorax ; the legs, and 

 especially the tibiae, are strongly compressed, so that although 

 fairly wide they are thin, with the outer part of each tibia 

 semi-transparent. From the species, atra, previously recorded 

 from Mount Tambourine, it is distinct by its pale colour, and 

 very different epaulettes and legs. 



COLYDIIDAE. 



EUCLARKIA, II. g. 



Head irregular, about as long as wide. Eyes small and 

 lateral. Antennae short, stout, three- jointed, first joint small 

 and almost concealed, second very short, third cylindrical, its 

 apex truncated. Palpi small, only apical joint of each ex- 

 posed. Prothorax subquadrate, strongly costate. Scutellurn 

 small. Elytra closely applied to prothorax, strongly costate; 

 epipleurae rather wide and parallel-sided to base of abdomen, 

 thence narrowed to apex. Metastemum elongate; episterna 

 rather narrow and parallel-sided. Abdomen composed of five 

 segments, first and fifth subequal in length, second much 

 shorter, third slightly shorter than second,, and fourth than 

 third. Legs short and fairly stout; front and middle coxae 

 moderately separated, the hind ones more widely so; femora 

 edentate; tibiae angularly dilated to beyond the middle, and 

 then strongly narrowed to apex; tarsi with claw-joint almost 

 as long as the rest combined, claws simple. 



This remarkable genus is clearly allied to Kershawia, 

 and in general appearance the species described below quite 

 strongly resembles K . n/r/iceps on a small scale; with antennae 

 removed there is no strong distinguishing feature. The 

 antennae at first glance appear to be but one-jointed, 

 but a very small basal joint (invisible from above) may be 

 seen, and a second one applied like a thin disk to the base of 

 the third, the latter has its apex slightly concave, and filled 

 with sensitised pubescence as in so many inquilines. The 

 mandibles are tightly clenched on all the specimens before 

 me. Only four distinct tarsal joints are visible. The elytral 

 episterna and base of abdomen on each side are somewhat 

 depressed for the partial reception of the hind legs when at 

 rest. Wings are present. 



EUCLARKIA COSTATA, 21. sp. 



PI. xxv., fig. 16. 



Rather narrow, depressed, opaque, with dense punctures 

 all over. Brown or black. 



Head truncated in front, sides incurved from between 

 antennae to eyes, beyond each of these a subcorneal projection,
