Group tifiscllala. 



Genus RHYNCHAGROTIS Smith. 



Anterior tibiiP not s[)inosc; antenna' of male simple; abdomen de- 

 pressed; thorax more or less dei)ressed, obsoletely tntted, or with small 

 divided crests. Primaries snbequal, onter margin rounded ; api?x 

 rounded or rectangular, pali)i forming a more or less evident snout. 



The above will suffice to distinguish the particular series of the 

 Agrotes to which it refers, in addition to what has already been said on 

 the subject. 



Three groups are united under this term, differing among themselves 

 in pattern of maculation and in the type of the male genitalia. 



Group ckardini/i is easily distinguished by the yellow secondaries. 



Group cupida contains species in which the maculation is complete 

 and the thorax is not, or not prominently, tufted. The palpi are most 

 evidently snout-like. , 



Group exserfisf if/ma contains species in which the orbicular is more 

 or less V-shaped, open to the costa which is usually more or less pallid. 

 The thoracic tufts are always evident, but scarcely i)rominent. 



The characters of the genitalia are discussed under the group head- 

 ings. 



Group CIIARDINYI. 



Anterior tibiae not spinose, front smooth, antenmp of male simple, flat- 

 tened, densely clothed with tine pubescence beneath, and with long 

 ciliic from each side of each joint, not pectinated as stated by Mr. Grote. 

 The thoracic vestiture is smooth, hairy, the hairs slightly flattened. 

 Abdomen depressed. Primaries rather short, broad, apices rectangu- 

 lar, outer margin straight, to the middle. Secondaries yellow with a 

 broad black margin and yellow fringes. 



This group, though placed with, and certainly very closely allied to 

 cupida, yet shows so many i)eculiar characteristics that it would seem 

 possible to separate it by a distinct generic term. The two species, 

 rufipectus and bnoincicoUis are, however, somewhat intermediate, and 

 as the species can hardly be referred to Tripha'^ia, I prefer to leave it
