wide, almost as long as protliorax, sides diminishing in width 

 from base to antennae, then obliquely dilated to apex ; basal 

 third with dense and rather coarse punctures, elsewhere with 

 small, and rather sparse ones. Prothorax moderately trans- 

 verse, convex, apex about half the width of middle ; with 

 dense partially-concealed punctures. Elytra almost thrice the 

 length of prothorax and about one-fourth wider, base 

 trisinuate, median sinus more pronounced than the others; 

 with rows of large, partially-concealed punctures ; interstices 

 narrower than punctures, except posteriorly. Under -but face 

 with somewhat irregularly distributed punctures, larger on 

 basal segment of abdomen than elsewhere. Length, 3 mm.

On the type, whose sex is doubtful, there are eight 

 whitish spots on the prothorax : four across middle, three near 

 apex, and an elongated medio -basal one. On each elytron 

 there is a small median and two subapical spots, but a few 

 white scales are scattered singly elsewhere. On the under- 

 surface the scales are sparse and mostly whitish. There are 

 three feeble whitish spots on the head. 



Leucothyreocis, n. g. 



Head fairly large, but almost concealed from above. 

 Eyes rather small, widely separated, coarsely faceted. 

 Rostrum of moderate length and width, distinctly curved. 

 Antennas moderately thin; scape inserted nearer apex than 

 base of rostrum and shorter than funicle; two basal joints of 

 funicle elongate; club ovate. Prothorax lightly transverse, 

 base bisinuate, sides rounded, apex produced. Scutellum dis- 

 tinct. Elytra strongly convex, narrowly cordate, each 

 separately rounded at base. Pectoral canal deep and wide, 

 terminated between middle coxas. Mesosternal receptacle 

 scarcely elevated above coxae, base rather large, emargination 

 widely transverse; cavernous. Metasternum long; episterna 

 distinct. Abdomen large, sutures straight, j&rst segment as 

 long as second and third combined, second as long as third 

 and fourth combined. Legs rather short; femora strongly 

 grooved and edentate; tibiae almost straight. 



Rather close to Tyrtceosus, but femora edentate and 

 strongly grooved. In the table of genera allied to Cryptor- 

 hynchus W would be associated with Queenslandica and 

 Scleropoides ; from both of which it is distinguished by the 

 straight apex of first abdominal segment, and elytra not 

 trisinuate at base. At a glance the typical species appears
