ALEURODICUS COCOIS. 
51 
■ '■■■ 
Two ocelli, large and conspicuous. Wings large, subopaque, median vein 
divided at two-thirds wing length. Costa of fore-wing finely crenulate to tip, 
furnished with sparse bristles arising below edge of wing. Costa of hind wing 
with 8 or 9 rather long bristles or hairs near base. Legs slender, moderately 
long, hind tibia with an internal row of bristles, tarsi 2-jointed, two large tarsal 
hooks, with a median basal hook-like appendage much smaller than the lateral 
hooks. Abdomen with six plain tergites, but five visible urites. Sixth tergite 
bearing a pronounced median curved papilla ; ovipositor acute. 
Adult male (fig. 39, k) [fig. 7, fc]. — Resembles the female except in being 
more slender and longer by virtue of the 
two large forficular claspers, nearly as 
long as the entire abdomen and which 
gave the average specimen a total length 
of 2.8 mm., as against 2.1 mm. for the 
female. Between the two claspers is a 
short curved style rather more than one- 
third the length of the claspers. Sixth 
tergite bears a median papilla and the 
fourth urite a similar one. Color of 
abdomen much darker than in female, 
particularly at hind border of segments ; 
claspers still darker. 
COCKERELL's DESCRIPTION OF ALEU- 
RODICUS IRIDESCENS. 
Agrees with A. asarumis in having 
some blackish coloration at the forking 
of the wing-vein, but differs in having 
the body and legs a deep chrome yellow, 
and the eyes not divided. Length of an- 
terior wing 2 mm. ; wings noticeably 
iridescent ; a blackish line on the costa. 
Pupae along the mid-rib of the leaf, as 
in Aleurodicus puliinala (Maskell as 
Aleurodes), surrounded by abundant cot- 
tony secretion. Pupa? dark grey or 
plumbeous, varying to brownish, struc- 
tural characters as usual in the genus. 
Yasiforrn orifice semicircular ; operculum 
very broad, broadly truncated at end. 
Four large round orifices on each side of Fig. 9. — Aleurodicus cocois: a, Skin of 
the abdomen, some distance from the 
margin, but not nearly so large as Maskell 
figures for pulvinata; four very much 
smaller orifices in the caudal region, laterad of the vasiform orifice, the two 
hindmost nearer to each other than are the anterior ones; two of the large 
orifices at the cephalic end, and also four small ones as in pulvinata, but they 
are very minute. 
Hab. — Ocean beach between El Faro and San Pedro, Tabasco, Mex., June 12, 
1897, on " Jicaco," a bush: with large leaves growing on the sand flats (Town- 
send) Div. Ent. 7824. 
In the original description there is little given by means of which 
this species could be distinguished from others in the same genus. 
full-grown larva from above.
