NEOJAPYX TROPICALIS, new species 
PLATE 34, Ficures 9, 10 
Description —Head with lateral margins almost straight and paral- 
lel. Antenna somewhat more than twice as long as head, number of 
segments 34 to 36; segment I about twice as broad as long; segment 
II with axis moderately outcurved; segment IIT slightly shorter than 
IV and not so broad. All antennal segments well provided with 
straight, or almost straight, setae which do not form rows. Mandible 
with distal tooth long, curved, sharp. 
Pronotum with well-developed median apodeme and well supplied 
with setae of varying lengths. Mesonotum with a large, distinct, mov- 
able prescutum, the latter bearing several setae including a conspicu- 
ous pair of stout, straight, submedian setae situated at the junction 
of the median apodeme with the posterior, marginal apodeme. Meta- 
notum larger than mesonotum and not so strongly sclerotized; pre- 
scutum without median apodeme and with a pair of stout, straight, 
submedian setae situated farther from posterior margin. First three 
pairs of thoracic spiracles visible; the other pair may be present but 
not detectable in the unstained specimen at hand. Tarsi each termi- 
nated by two very unequal, lateral claws and a minute median claw. 
Each lateral claw bears a somewhat indistinct basal tooth. 
Abdomen with terga II to VI subequal, each having a transverse 
line near its anterior end, in front of which there appear to be no setae. 
Segment VII of abdomen intermediate in width between VI and VIII; 
segment VIII with sides almost parallel and bearing several conspicu- 
ous setae near posterior border; segment IX of the usual shape and 
bearing dorsally several small to minute setae. Subcoxal organs of 
segment I each with a fringe of subequal setae which are not arranged 
in a definite row. Styli each with a poorly developed basal spur and 
a single curved seta. Forceps equal except that the left arm has two 
rows of teeth on the basal part, four teeth being in the upper and three 
in the lower row. For the other characters of the forceps see figure 10. 
Length of body, including forceps, 7.6 mm.; width (that of segment 
ITT of abdomen), 0.8 mm. 
Type locality—Georgetown, British Guiana. “Quarantine at Phila- 
delphia, Pa., on soil of potted palm.” 
Type (holotype). —U.S.N.M. No. 55219. 
Remarks.—Description based on the holotype, the only specimen at 
hand, which was taken in June 1921, through the Government quaran- 
tine service. 
The alimentary canal of the single specimen of this species is filled 
for most of its length with partially digested food material. In the
