46 CLASSIFICATION OF THE ALEYRODIDiE. 
Aleurodicus coccolobse n. sp. 
(Plate XI, figs! 1-8.) 
Collected on seagrape* (Coccoloba uvifera), Progreso, Yucatan, by 
Samuel Henshaw, June 24, 1904, and forwarded to the Bureau of 
Entomology by Professor Cockerell. Only a fragment of leaf bear- 
ing a few pupae is at hand, but the species is so distinct that its 
recognition from the pupal stage alone will be easy. 
DESCRIPTION. 
Pupa case. — Size 1.25 mm. by 0.85 mm. ; elliptical in outline, mod- 
erately convex. As seen under hand lens the abdominal segments are 
quite distinct as transverse ridges. Color dull }^ellowish; para- 
sitized specimens brownish black or plumbeous. There is a fairly 
abundant secretion of wax more or less hiding the insects beneath. 
The secretion consists of the usual long wax rods from the compound 
wax pores and a fairly copious secretion of semiflocculent or cottony 
wax from dorsum of case. There is a secretion all around of a 
narrow, short rim of fused glassy wax, seen best upon the removal 
of the more abundant flocculent secretion, and which largely per- 
sists on the leaf after removal of case (PI. XI, fig. 2). 
Under the microscope the case is pale yellow to almost colorless. 
Dorsum of case thickly covered with pores which, however, in the 
nonparasitized individuals, are made out with some difficulty. On 
the more central dorsal area, or dorsal disc, the pores are fairly large 
and scattered promiscuously. The smaller pores occur in a sub- 
marginal zone all around the case, and just within margin all 
around is a closely set row of pores somewhat larger than those on 
the dorsal disc (PI. XI, fig. 2). The location of these pores is very 
evident in parasitized pupae (PL XI, fig. 1), which condition ap- 
parently produces rather important structural changes in the pores. 
In the case of the pores on the dorsal disc there is produced from 
center of pore a short papilla or peg, acute, rounded, or swollen 
at tip. From each of the smaller pores forming the submarginal 
zone is produced a short finger-like process. The pores just within 
margin of case all around show a group of small dark granules 
surrounded by many minute granulations. In the single parasitized 
pupa of jamaicensis, constituting the type of this species, are to be 
noted the same minute finger-like processes from the submarginal 
zone of pores, but the dorsal pores above mentioned appear to be 
wanting in jamaicensis, and in comparing the lingulaa the species 
are readily seen to be different. 
Margin and dorsum of case apparently without spines, except a 
pair on caudal end of case.
