198 NEW SPECIES OP AUSTRALIAN COLEOPTERA, VIII., 



invisible from others. Another species* before me also has very 

 narrow front tarsi in the female; the terminal joint of its palpi, 

 however, is more distinct than in either of the above species. 

 With variable palpi and tarsi therefore it seems quite possible 

 that it may be afterwards desirable to unite Hyperomma and 

 Suniopsis. 



At first sight very close to H. pictipes, but readily distinguished 

 by its darker colour and by the punctures of prothorax, elytra 

 and abdomen; the two are readily distinguished from H. lacerti- 

 itum and II. abnorme by their much smaller size, etc. 



S U N I U S. 



The species of this genus hitherto described are all winged, but 

 below will be found descriptions of two apterous species Those 

 known to me may be tabulated as follows : — 



Apterous. 



Abdominal punctures in transverse series Simsoni, n.sp. 



Abdominal punctures dense and irregular favosus, n.sp. 



Winged. 



Form very robust for the genus, f 



Base of elytra dark HacJceri, n. sp. 



Base of elytra not dark brevicollis Lea. 



Form of normal tenuity. 



Prothorax darker at sides than on disc cylindricus Macl. 



Prothorax of uniform colour. 



Elytra maculate guttula Fvl. 



Elytra of uniform colour or almost so cequalis Blackb. 



Elytra flavous at apex apici/lavus Lea. 



Elytra with longitudinal markings trilineatus Lea. 



Sunius Simsoni, n.sp. 



Of a leather pale reddish-brown; head, basal half of elytra and 

 5th and 6th segments of abdomen dark brown or black; legs 

 flavous. antennae and palpi somewhat darker. Clothed with 

 straggling blackish hairs and with sparse greyish pubescence. 



* The largest of the genus, but my specimen is too damaged to be 

 described. 



tThese two species are fully twice as robust as the common S. guttula, 

 and their elytra are considerably larger.
