COLEOPTEEA.—LEA. 183 



rounded ; punctures much as on prothorax ; nonstriated. Intereoxal process of 

 prosternum just passing hind coxie, its tip truncated; middle coxae separated 

 slightly more than front ones, and about half the distance of hind ones. Legs 

 stout, three basal joints of front and of middle tarsi wide, of the hind ones 

 rather narrow. Length, 3-4-5 mm.

The markings of the prothorax readily distinguish this species from 

 C. niger and all others known to me. The dark parts vary from rather lightly 

 infuscated to deep black; they irregularly cover the head between the eyes and 

 about two-thirds of the prothorax, so that several pale spots are enclosed in front, 

 and the hind margin has four lobes : the elytra vary from entirely pale, or with 

 the sides faintly infuscated, to almost entirely dark, but usually they have a 

 large obscurely pale triangle about the scutellum; the club (except part of the 

 apical joint) and parts of the metasternum are also dark. The dark markings 

 of the head are usually extended so as to leave but two small pale spots at the 

 base ; on one Brisbane specimen the prothoracic markings are reduced to three 

 irregular, disconnected, infuscated spots. On many specimens the abdomen is 

 covered by the elytra, on others part of the pygidium is exposed. 



CYCHRAMUS INCONSTANS ap. nov. 



Colour and clothing variable. 



Head with rather dense but partially concealed punctures ; clypeal suture 

 shallow and semicircular ; labrum deeply notched. AntennjB long and thin, first 

 joint slightly longer than third, and about thrice the length of second, ninth 

 elongate-triangular, apex incurved, tenth shorter than ninth but of the same 

 width and longer and slightly wider than eleventh, sides gently rounded, apex 

 incurved, eleventh subcircular. Prothorax at base more than twice as wide as 

 the median length, sides strongly rounded and finely margined, apex gently 

 incurved to middle, and about two-thirds the width of base ; punctures as on 

 head. Scutellum rather large and semicircular. Elytra, when at rest, with sides 

 continuous with those of prothorax, gently decreasing to apex, leaving most of 

 pygidium exposed ; punctures dense, partially concealed, and more or less . 

 asperate. Intereoxal process of prosternum evenly convex, truncated posteriorly. 

 Legs stout, three basal joints of front and of middle tarsi wide, of the hind ones 

 less wide. Length, 4-8 mm.

The long antennae with loosely articulated club are at variance with other 

 species of Cychramus, but as I am not prepared to propose a new genus for the
