1142 COLEOPTERA 



the head. Elytra broader than thorax, yet not much broader at 

 the base, widest behind, closely punctate. 



Underside finely pubescent, sternum testaceous, abdomen infus- 

 cate. Femora robust, tibiae straight, their apical spurs distinct. 



An easily-recognised species. The only variegation on the wing- 

 cases consists of an ill-defined dark apical space, which, moreover, 

 is often altogether wanting. The elytral clothing, except under a 

 strong lens, appears to consist of fine brassy setae. 



Length, 2 lines ; breadth, f line. 



Mount Arthur. Cheeseman and Adams. 



2025. M. laticeps, n.s. Elongate, not broad, subdepressed, 

 a little nitid ; head and thorax rufo-castaneous, not densely covered 

 with yellowish hairs ; elytra fusco- testaceous, variegated with 

 darker marks, densely clothed with short, pale hairs ; antennae, in 

 colour, like the head, terminal joints occasionally darker; legs 

 testaceous, maxillary palpi blackish. 



Head broad, somewhat inflated behind the prominent eyes, so 

 sculptured as to seem finely granulate, with a puncture in each 

 granule. Antenna stout, not very elongate, third joint shorter than 

 fourth but longer than second. Thorax sculptured in the same 

 way as the head, short, apex more feebly sinuous than base, sides 

 slightly rounded, none of the angles prominent. Elytra broader 

 than thorax, not very much so at the base, broadest between the 

 hind thighs yet not very much dilated even there, indistinctly de- 

 pressed before the middle ; closely and finely punctate. Legs stout, 

 tibiae straight. Underside infuscate. 



The rather large head (somewhat flattened between the eyes), 

 rather slender palpi, and much less obvious granular sculpture dis- 

 tinguish this species from M. monticola and M. granulatus, both of 

 which are, moreover, somewhat larger. 



In one example the wing-cases are quite unicolorous ; in another 

 they are variegated with fuscous marks similar to those seen in M. 

 marmoratus . There is a variety in which the head and thorax are 

 infuscate and the former unimpressed ; these differences are accom- 

 panied by a still greater variegation of the elytra, and these darker 

 portions are due to the colour of the derm itself as well as to the 

 variegation of the pubescence. 



Length, lf-2 lines; breadth, f- line. 



Evidently a common species on Mount Arthur, from whence 

 numerous examples were brought by Messrs. Cheeseman and 

 Adams ^ 



These gentlemen also found some specimens of M. divergens, 

 some of which are so dark in colour that the elytra may be described 

 as being dusky-brown marbled with pale-brown, whilst the legs and 

 lower surface are equally dark. 



Cyphotelus angustifrons is another desirable species obtained in 

 the same locality. It is a rather elongate, parallel-sided insect, 

 sometimes wholly black, sometimes testaceous, and having the 

 appearance of a narrow Atopida.
