Types in Coll. Sloarie. I obtained a large number of speci- 

 mens (many immature) on sandbanks of the Laura River (which 

 had ceased running) beside the railway-bridge at Laura, by 

 Hooding the margins of the pools left in the river It is verv 

 active, and, on being driven from its shelter in the sand bv 

 water, runs with great celerity, and quickly hides itself again in 

 crevices in the sand. 



The colour of the elytra is variable; looking at the elytra from 

 the base, the dark part of the pattern, which varies in colour 

 from brown to piceous, is seen to be a postbasal area covering 

 the four inner interstices, constricted almost to first interstice 

 at basal third, then spreading obliquely outwards and extending^ 

 over the eighth interstice behind apical third, and forming a 

 wide transverse area above the apical declivity: the apex ( widely) 

 and the sides (irregularly; are lighter-coloured: the more light) v 

 coloured parts of the elytra vary from brown to pale testaceous, 

 according to the maturity or immaturity of the specimen ex- 

 amined. The prothorax has a short bristle-like seta at each 

 anterior angle, and another similar, but longer, seta beside the 

 lateral border at widest part, but there is no basal marginal 

 seta. The basal marginal seta is also wanting in all those species 

 of the genus Endalia^ which have not the lateral margins of the 

 prothorax plurisetose: the presence of this seta is rare in the 

 tribe.
