of 2nd or 5th. Femora almost equally dentate, posterior termin- 

 ating before apical segment of abdomen; tibiae compressed, almost 

 straight, wider at base than near apex. Length 4 J, rostrum 1; 

 width 2 mm. 



Hob. — Tasmania and Victoria. 



The prothoracic fascicles, though of moderate size, are scarcely 

 defined on account of the looseness of the scales by which they 

 are surrounded. 



ACROTYCHREUS, n.g. 



Head small, much depressed between eyes. Eyes prominent, 

 round, rather coarsely faceted, distant. Rostrum moderately 

 long, not cylindrical, curved, sides feebly incurved to middle. 

 Antennce rather thin; scape inserted nearer apex than base of 

 rostrum, slightly shorter than funicle; two basal joints of funicle 

 elongate; club rather large, elongate-elliptic, the length of six 

 apical joints of funicle. Prothorax transversely subtriangular, 

 apex produced, base bisinuate; ocular lobes almost rectangular. 

 .Scutellum distinct. Elytra wider and less than thrice the length 

 of prothorax, convex, strongly raised in middle. Pectoral canal 

 moderately wide and deep, terminated between middle coxa?. 

 Mesosternal receptacle raised, walls thin and U-shaped, slightly 

 cavernous. Metasternum decidedly shorter than basal segment of 

 abdomen; episterna large. Sutures of abdomen distinct, 1st 

 segment almost twice the length of 2nd, 2nd not much longer 

 than 3rd or 4th, these conjointly considerably longer than 5th. 

 Femora stout, clavate, grooved and largely and angularly dentate; 

 tibiae long, thin, compressed, strongly curved; tarsi long and thin, 

 3rd joint deeply bilobed but not very wide. Short, outline 

 angular, convex, densely squamose, fasciculate, tuberculate, 

 winged. 



This genus is erected to receive Tychreus fasciculatus, wrongly 

 referred to Tychreus. The shape of the head, granulation of 

 eyes, shape of abdominal segments, shape and dentition of femora, 

 and shape of tibiae are at variance with Tychreus. The fascicles 

 and general shape present a very misleading resemblance to T. 

 camelus.
