simple but irregular in shape ; the sedoeagus is large and 

 straight, with the copious vesica heavily shagreened. 



Maenas punctatostrigata, B.-B. 



This genus seems to me to be very highly developed, so far 

 as these organs are concerned, in that they are unusually 

 simple in structure ; in each case the cingula and the tegumen 

 are fused together in the tergite as in the Rhopalocera, though 

 the uncal extremity retains the typical form of the group; 

 the harpagones are rounded for the basal half, but have 

 an elongated arm projected along the upper margin; the 

 sedoeagus is of very moderate proportions with a small and 

 simple vesica. 



Rhodogastria crokeri, Macl., 



has the tegumen very undeveloped, in the present species it 

 is of the smallest size, slightly hooded with a minute point 

 along the dorsal line, other species have no more than the 

 narrow collar of the cingula or girdle ; the harpago is large, 

 pyriform, broad at its narrow end with a long hook shortly 

 barbed on its outer surface ; the sedoeagus at rest is short, 

 very broad and somewhat bulbous at the rear, but when 

 extended it is seen that the vesica is highly shagreened, with 

 a most formidable termination closely similar in shape to a 

 pelican's beak and as powerful looking. 



The most interesting feature of the genus is, however, the 

 development of scent organs on the outside of the harpagones ; 

 they lie curled up in a hollow on the centre of the exterior and 

 are protected by fringes of long hair ; they consist of a single 

 long, tapering, very fine membranous sac, one in each clasp, 

 and are studded with short-pointed setae, terminating in a 

 fringe of longish hairs. I will do no more than make this 

 reference to them here as I am describing them more in detail 

 elsewhere. 



Syntomis phegea, L., 



has the cingula somewhat similar to Parasemia. but with 

 the saccus reduced, whilst the tegumen is extended; it has 

 heavy laterals, the dorsum is also larger, and the uncal ex- 

 tremity more heavily built; the harpagones are somewhat
