this family. The lobes which indicate the presence of pilifers are not 

 well developed and the maxillae are short (Fig. 69). The body is 

 short and thick and covered on the dorsum of the thorax and abdo- 

 men with short spines. A strongly elevated median ridge is also 

 present on the thorax and on the first eight abdominal segments. The 

 prothorax is very long, at least half the length of the mesothorax. 



The following species was examined : 

 Galleria melonella Linnaeus. 



Subfamily Crambinae 



The pupae of the Crambinae are easily recognized by the peculiar 

 form of the short, blunt cremaster and the deep lateral grooves on the 

 tenth abdominal segment. Some of the species show a large portion 

 of the labial palpi, indicating that this subfamily is one of the more 

 generalized. The maxillae reach almost to the caudal margin of the 

 wings and the tips of the mesothoracic legs meet on the meson just 

 caudad of the maxillae. The segments are almost smooth, never 

 punctate. 



The following species were examined : 

 Crambus vulgivagellus Clemens, trisectus Walker, caliginosellus Clem- 

 ens. 



Subfamily Pyralinae 



The species of this subfamily resemble closely the genera Plodia 

 and Ephestia of the Phycitinae. There scarcely seems to be more than 

 generic differences between them. The epicranial suture is present 

 and the vertex always extends to the meson. The maxillary palpi are 

 well developed and usually reach the proximo-lateral angles of the 

 maxillae. There is never a cremaster present, but a transverse row of 

 hooked setae at the caudal end of the body. The two genera studied 

 may be separated as follows : 



a. Dorsum of abdomen with a furrow between the ninth and tenth seg- 

 ments, the caudal margin of the furrow distinctly crenulate. 



Pyralis Linnaeus. 



aa. Dorsum of abdomen without a furrow between the ninth and tenth 



segments Eypsopygia Hiibner. 



The following species were examined : 

 Pyralis farinalis Linnaeus 

 Hypsopygia costalis Fabricius
