species were to be referred to the Cryjjtorhynchides on account of 

 their prosternum anteriorly concave, the combination of con- 

 tiguous anterior coxaj with the absence of a strong mucro at the 

 apex of the anterior tibiae would distinguish thena from all known 

 Australian genera. 



Emplesis scolopax, Pasc. 



This species appears to be distinguished from all others described 

 by Mr. Pascoe or known to me by the well-denned fascicle of 

 coarse scales on the forehead ; these, however, are very easily 

 rubbed off, and I possess only two examples in which they are 

 very conspicuous. Mr. Pascoe seems to have known only one 

 sex, as he characterises the rostrum as equalling in length half 

 the body. This is no doubt the female ; in my examples of this 

 sex the rostrum is not quite equal to half the body when exactly 

 measured, but it appears quite so to the eye. In specimens of 

 the other sex (they were taken in company with those having the 

 long rostrum and present no other difference) the rostrum is 

 considerably shorter (being of the length of the anterior femur), 

 and is stouter at the base, but narrower slightly at the apex, and 

 the antennae are inserted (not as in the female at the middle but) 

 well in front of the middle of the rostrum. The 1st joint of the 

 antennal funiculus is about half again as long as the 2ncl, the 2nd 

 about half again as long as the 3rd ; the club is about as long as 

 joints 5-7 together. In all the examples before me there is a 

 conspicuous depression on the basal ventral segment. 



Emplesis simplex, Pasc. 



As all the examples of Emplesis before me are from S. Australia, 

 this is the only one besides scolopax of those described by Mr. 

 Pascoe which is likely to be among them. The description, how- 

 ever, of this species will not allow of my attributing any example 

 to it. It appears to be smaller than scolopax, and to have the 

 rostrum more arched and no fascicle of scales on the forehead ; it 

 would seem also that the scales with which it is clothed are all of 

 uniform colour. Unfortunately Mr. Pascoe gives no information
