Cassythicola n. g. 



Head small. Eyes fairly large, moderately faceted, separated 

 almost the width of rostrum at base. Rostrum long, thin and 

 curved. Scrobes submedian , rather suddenly directed beneath 

 rostrum and touching lower margin of eyes. Scape elongate ; 

 two basal joints of funicle elongate , but first distiuctly longer 

 than second; club elongate. Prothorax strongly transverse, base 

 much wider than apex. Scutellum distinct. Elytra widely sub- 

 cordate , strongly convex. Metasternum along middle about half 

 the length of the following segment. Abdomen with basal segment 

 along middle almost as long as the three following combined, 

 second distinctly but not much longer than third or fourth. 

 Front coxae lightly but distinctly separated , very little space 

 between them and apex of prosternum, middle coxae moderately, 

 the hind pair widely separated ; femora rather stout , edentate ; 

 tibiae rather stout ; third tarsal Joint rather wide and deeply 

 bilobed, fourth rather long ; claws moderately separated. 



The eyes are neither coarsely nor finely faceted ; but regar- 

 ding them as fine then in Blackburn's table the genus should 

 be placed with Olanaea and Rhaciodes , to neither of which is 

 it at all close. Regarding the facets as coarse the genus should 

 be placed with Gerynassa, Ethas and Omorophius ; with the two 

 latter genera it has little in common, and despite the Separation 

 of the front coxae I cannot but regard it as closely allied to 

 Gerynassa. Compared with that genus the two species described 

 below differ (apart from the coxae) in being wider and more rounded, 

 rostrum longer , scape with second Joint distinctly shorter than 

 first (in several species of Gerynassa , however , the second Joint 

 is shorter than the first) , and eyes smaller , with finer facets. 

 Numerous specimens of rotundata were beaten from a curious 

 parasitic vine of the genus Cassytha,

Reddish; sterna and part of abdomen usually black or 

 blackish. Moderately densely clothed with scales , more or less 

 variable in colour. 



Head small but increasing in width to base, with concealed 

 punctures. Rostrum as long as head and prothorax combined, 

 moderately and evenly curved; with minute punctures, in front 

 of antennae but larger behind same , with a distinct carina on 

 each side of basal half. Scape inserted slightly nearer apex than 

 base of rostrum, and longer than funicle; first Joint of funicle 

 about once and one half the length of second; club the longtli 

 of five preceding joints combined. Prothorax almost tvvice as
