pharynx can always be removed entire. To the above description 

 1 may add that the apical pair of bristles of the mandibles 

 [fig. 6] are present, though slender, the labrum and hypo- 

 pharj'nx [fig. 7] as in other species; the labium [fig. 8] has the 

 middle tooth trifid, and there are three setae (instead of one,, 

 as Kiley has it) in each row on the ventral side. The maxillary 

 palpi have a few slender setae and there are also a few on the 

 basal joint [fig. 9]. 



I find eight abdominal segments plus the anal segment in the 

 pupa [fig. 10], and not nine, as Riley has it. Therefore the 

 eight hooks are on each of segments 2, 3 and 4, and not 3, 4 and 

 5. Dorsally, on each of segments 5, 6 and 9 is a transverse row 

 of minute caudad projecting spines; 7 and 8 with slightly larger 

 ones. Yentrally, segments 5, 6 and 7 each with four large 

 spines curved cephalad. In the Cornell University collection 

 are four specimens of adults, two males and two females, ob- 

 tained from Riley.
