pharynx can always be removed entire. To the above description 
I may add that the apical pair of bristles of the mandibles 
[fig. 6] are present, though slender, the labrum and hypo- 
pharynx [fig. 7] as in other species; the labium [fig. 8] has the- 
middle tooth trifid, and there are three setae (instead of one, 
as Riley 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 
Y 
ones. Ventrally, 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.

tinctly separated from the small by a horizontal line. Face 
small, as broad opposite the insertion of the antennae as its 
length, considerably narrowed below; a deep groove on either 
side running obliquely to the inferior angle, the median part 
arched; in color grayish pruinose, or in some reflections almost 
silvery; antennae situated at about the lower fourth in profile; 
in color black with a slight pruinosity; palpi black, slender, the 
first three joints somewhat thickened. Metanotum thinly 
covered with golden pubescence; in color velvet-black, the 
lateral margins and a spot running upward and inward from 
each humerus gray and yellowish gray, but somewhat variable 
in different reflections. Mesad of these gray humeral spots isa 
pair of small silvery spots. Pleurae, pectus and coxae, gray 
pruinose, showing in some reflections the black ground color. 
Abdomen with eight visible segments, in color deep velvet-black; 
under the leaflike margins of the first segments and the sides — 
of the remaining segments gray, or in some reflections silvery
