ceous. The frontal costa is rather thickly pilose with stiff black hairs. 

 The antennae are about four times as long as the body. The pronotum 

 is only slightly narrowed anteriorly, less than one and a half times as 

 wide as long and usually sparsely pilose with long bristly hairs. Teg- 



mina of the male about two-thirds as long 

 as the abdomen, truncate or very slightly 

 arcuate posteriorly with the external and 

 internal posterior angles extended into 

 rather distinct spines ; speculum very 

 large, including nearly all of the dorsal 

 field, the apical field therefore very much 

 reduced ; wings apparently obsolete. The 

 anterior and middle femora are strongly 

 compressed, the latter decidedly arcuate. 

 The posterior tibiag are armed with three 

 spines on both the inner and outer angles ; 

 these spines are situated on the apical half, 

 the lowermost inner one being half as long 

 as the tibite and about as long as the 

 metatarsus ; spurs of the posterior tibial, 

 three, on both the inner and outer side, 

 the upper inner one being about as long as 

 the metatarsus, the latter a little less than 

 twice as long as the two joints of the 

 tarsus. Cerci about as long as the head

The collection contains about 

 twenty-three specimens of Nemobius., 

 all collected at the same time in a 

 single locality. Unfortunately only 

 two of them are mature, and both 

 are males, though a considerable 

 number of both males and females 

 are in next to the last moult. Since the tables for determining 

 species in this large genus (at least forty-five species are described) 

 are generally based on the females, and since in many cases the males 

 are not known, I have not been able to satisfactorily determine the 

 position of this species; but since all species indigenous to the Gala-
