'766 AUSTRALIAN AND TASMANIAN PBELAPHIDiE, 



Tlie apical dorsal segmenfc of the abdomen is large, rounded at 

 apex, and produced over the pygidium, which in consequence 

 appears to be ventral. At a casual glance, the head, prothorax, 

 and elytra appear to be glabrous; but, on close examination, fine 

 sparse pubescence becomes visible; the elytra also are tipped with 

 very fine and regular pubescence. From some directions a very 

 ■vague longitudinal impression can be seen between the eyes. 



Tyromorphus auuicomus, n.sp. (Plate xxi., fig. 9}. 



^. Brownish-castaneous, sometimes almost piceous, appendages 

 .and part of elytra paler, ])alpi flavous. With moderately long 

 pubescence on upper surface, denser on abdomen and tips of 

 elytra than elsewhere; lower surface of abdomen with a con- 

 spicuous, more or less golden, fringe at extreme base. 



Head distinctly transverse; with two round fovese of moderate 

 size slightly in advance of the eyes, and with a rather deep depres- 

 sion between the antennary ridges. Antennae moderately long, 

 first joint subcylindrical, slightly longer than second and third 

 combined, third to eighth feebly and regularly diminishing in 

 dength, witli the eightli distinctly transverse, ninth and tenth 

 rather large and subquadrate, eleventh slightly longer than ninth 

 .and tenth combined, its apex distinctly curved. Palpi rather 

 long, first joint very small, second almost as long as third and 

 fourth combined, thin at base, with the apical half moderately 

 inflated, third thin at base and regularly inflated to apex, fourth 

 once and one-half the length of third, thin at the base, with the 

 apical two-thirds elliptic-ovate, and tipped with a seta. Pro- 

 thorax almost as long as wide, widest near apex, the sides thence 

 gfiitly decreasing in width to base; with a small deep fovea in 

 middle near base, but without latero-basal fovese; with small and 

 rather sparse punctures. Elytra about three-fourths as long as 

 wide, sides gently rounded, apex scarcely wider than across 

 shoulders; dorsal striae deep at base, and traceable to beyond the 

 middle; with numerous rather distinct punctures. Upper surface 

 of abdomen decreasing in width from base to apex, second segment 

 longer than third, but shorter than fifth, third about once and
