appear emarginated at its apex ; and they may be divided 

 into the following sections : — 



1. Prosternum from apex halfway or almost halfway to 

 cox3e, with a shallow groove, bordered by distinct and usu- 

 ally carinated ridges.'^ This section is the most numerously 

 represented in Australia, and is allied to European species, 

 such as scolopacca. 



2. Like Section 1, but with the frontal ridges of the pro- 

 sternum continued to between the coxae ; the eyes also are more 

 coarsely faceted than is usual in the family. 



3. Prosternal groove as in Section 1, but rostrum sub- 

 gibbous at base. 



4. Prosternum with a shallow and wide groove to be- 

 tween coxae, not bounded by carinated ridges, and with two 

 distinct punctures in front. 



5. Prosternum without grooves and ridges in front, but 

 with two distinct punctures marking the position of the 

 ridges, t 



6. Prosternum as in Section 1, but rostrum suddenly 

 gibbous at base. 



7. Pectoral canal narrow and continuous to between an- 

 terior coxae, and bounded by ridges (but which are not cari- 

 nated). Tip of abdomen just j^erceptibly emarginated. The 

 pectoral canal is more distinct than in the other sections, 

 being much as in the European abrofani, with which, how- 

 ever, eheninu has little else in common. 



8. As Section 6, but rostrum much shorter. 



The following table of species known to me is arranged 

 for convenience of identification only : — 



Elj tral interstices with coarse punc- 

 tures porosa. 



Elytral interstices not coarsely punc- 

 tate. 

 Upper surface with clothing in iso- 

 lated patches. 

 Prothorax and elytra both with 

 scales, 

 Elytral markings transverse ... niveonotata. 

 Elytral markings longitudinal. 

 Prothorax Avith four isolated 



spots ... leucospila. 



Prothorax with two stripes ... devia. 



* These ridges, however, can usually be seen with dijfficulty, 

 until the head is removed. 



t These punctures are to be seen in several other sections, but 

 are usually concealed by the clothing.
