Forehead somewhat sinuous. Eyes rather coarsely- 

 faceted. Elytra much wider than prothorax, base trisinuate. 

 Mesosterual receptacle somewhat depressed in front, walls 

 rather thin and U-shaped; cavernous. Metasternum some- 

 what shorter than the following segment; episterna wide. 

 Legs moderately long; femora obtusely dentate. Body 

 wingfed. 



Gyg^us prodigus, Pasc.(9) 



I am indebted to Dr. Gestro for a Fly River co-type of 

 this species. It, and four specimens from the Coen River 

 (North Queensland), all have the rostrum black, whereas the 

 type was described as having it castaneous, but this may have 

 been due to immaturity or to individual variation. The 

 sulcus at its apical sides is simply a feeble continuation of the 

 scrobe. The second joint of the funicle is distinctly longer 

 than the first. On the prothorax there is a feeble median 

 carina, which at the base appears as a scutellar lobe, and at 

 the apex as a fasciculated crest. On each side of the suture, 

 near the base, there are some small, shining granules, varying 

 in number from three to six. 



Gyg^us squamiventris, n. sp. 



d. Black; antennae and tarsi more or less reddish. 

 Densely clothed with rusty-brown or light-brown scales, more 

 or less conspicuously variegated with greyish or stramineous 

 ones; elytra in places with sooty scales. With numerous 

 stout, suberect scales scattered about, and on swellings con- 

 densed into fascicles. Abdomen with sooty scales, except at 

 base and sides. 



Head with concealed punctures; forehead lightly 

 sinuous. Rostrum long and rather thin, sides lightly incurved 

 to middle ; apical third with dense and not very small 

 punctures, elsewhere punctures concealed, but with a distinct 

 median carina. Scape inserted about two-fifths from apex 

 of rostrum, the length of funicle ; first joint of funicle slightly 

 shorter than second; club elongate, sutures oblique. Pro- 

 thorax moderately transverse, sides strongly rounded ; with a 

 short median carina; with feeble swellings, supporting four 

 distinct fascicles across middle, and two at apex; with large, 

 dense, concealed punctures. Scutellum moderately large. 

 Elytra about once and one-half as wide as long, distinctly 

 wider than prothorax; with rows of large, partially-concealed 

 punctures ; suture with numerous shining granules on basal 

 half and with a distinct fascicle crowning the posterior 

 declivity; third interstice with a distinct fascicle near middle,.
