green, but sometimes are ashen. On each individual, however, 

 they are generally constant in colour. 



As the elytra at the base are certainly wider (although not by 

 much) than the prothorax, I have referred the species to Myllocerus, 

 rather than to Synomiis. In general appearance it certainly some- 

 what resembles S. ivruginosus, and like that species the wings are 

 almost obsolete, so as to be quite useless for flight. At the time I 

 described ceruginosns, I believed Synomiis to be a good genus, but 

 the present species appears to cause doubts as to its validity. The 

 elytra are dilated from near base somewhat as in M. trepidus, but 

 the two species are not all closely allied. 



535. MYLLOCERUS MASTERSI n. sp. 



Dark reddish brown or piceous, sometimes black; antenn<ie and 

 legs (the femora sometimes excepted) more or less reddish. Densely 

 clothed with pale green scales, frequently with a slight coppery 

 gloss. In addition with thin whitish setse, more noticeable on the 

 elytra (where they are suberect) than elsewhere, and usually for- 

 ming one distinct row on each interstice. 



Eyes large and strongly convex. Rostrum (excluding mandibles) 

 slightly wider than ioi]g, sides very feebly incurved, apex very 

 little narrower than hase; sublateral carinae strongly curved, but 

 almost concealed ; with a line and usually concealed median carina. 

 Antennae thin; scape rather suddenly curved at middle; first joint 

 of funicle slightly longer than second and third combined, second 

 slightly longer than third and fourth combined. Prothorax almost 

 as long as wide, sides moderately rounded, base distinctly bisinuate, 

 apex almost truncate and as wide as base; with rather large but 

 almost concealed punctures. Elytra considerably wider than protho- 

 rax, parallel-sided to beyond the middle; with regular rows of 

 rather large but partially concealed punctures; interstices feebly 

 separately convex. Femora, especially the hind pair, acutely den- 

 tate. Length 3 1/2-5 mill. 



Hah. : N. W. Australia (Macleay Museum). 



A small, green, rather narrow species, readily distinguished from 

 most green species by its acutely dentate hind femora. Trepidus has 

 the prothorax considerably wider, elytra not parallel-sided and the 

 funicle different; grains has the prothorax striped and rostrum and 

 funicle different. 



On the elytra of seven of the thirteen specimens before me there 

 are small and irregularly distributed spots of almost black scales, 

 varying in number from one to fourteen on each elytra. One spe-
