On a neio Bat from Northern Nigeria. 447 



$ . Mari similis ; segmentis dorsalibus secundo tertioque fascia 



transversa augiista undulata utrinque sordide albidis. 

 Var. (S . Clypeo labroque plus minus sordide albidis. 

 Long., cJ 5, 14-15 mm. 



S . Antenna normal, the apical joint stout, not curved, 

 blunt at the apex. Clypeus rather strongly convex, truncate 

 at the apex, depressed on the middle of the apical margin. 

 Eyes diverging slightly below. Basal joint of fore tarsus 

 with seven spines ; intermediate femora not serrate. Second 

 ventral segment unarmed, sometimes with a very obscure 

 longitudinal carina ; sixth ventral segment with an obscure 

 longitudinal carina, sometimes almost obsolete, also with an 

 obscure oblique carina on each side converging towards the 

 apex, the enclosed space more sparsely punctured than the 

 rest of the segment, the apical margin of the segment 

 slightly undulating ; seventh ventral segment with a well- 

 marked longitudinal carina; seventh dorsal segment broadly 

 rounded at the apex. Anterior wing nearly two-and-a-half 

 times as long as the breadth of the thorax, third cubital cell 

 about equally long on the radius and on the cubitus. 



? . Seven spines on the basal joint of the anterior tarsus; 

 second ventral segment sparsely punctured in the middle, 

 more closely and finely on the sides ; sixth ventral segment 

 convex, subcarinate longitudinally in the middle ; sixth 

 dorsal segment narrowly rounded at the apex. 



Hab. Yallingup and Busselton, W.A. ; December and 

 January {Turner). 



This belongs to the group of B. variabilis, but is easily 

 distinguished by the difference in colour, by the much less 

 developed carina of the second ventral segment, and by the 

 different shape of the seventh dorsal segment. The female 

 has the sixth dorsal segment more rounded at the apex than 

 in variabilis and much more sparsely punctured.

Scotcecus falabce, sp. n. 



A medium-sized brown species, rather larger tlian S. hirundo. 



General characters very much as in S. hirundo, to which 



the new form is most nearly allied. Size rather larger.
