The Pink Bollworm 
349 
Frontal punctures (Fa) close together, anterior to frontal setae (F t ); distance between 
punctures less than distance between puncture (Fa) and setae (F t ); frontal setae (FJ 
and adfrontal setae (Ad^ and Adf 2 ) nearly equidistant; second adfrontal seta (Adf 2 ) 
approximate to but before beginning of longitudinal ridge (LR); adfrontal puncture 
(Adfa) midway between adfrontal setae. 
Epicranium with normal number of primary setae, 13, and punctures, 7, and with 
three small ultraposterior punctures, 1 (x, y, and z). 2 
Anterior setae 3 (A lf A 2 , A 3 ) in a slightly obtuse angle; A t and A 2 closer together 
than A 2 and A 3 ; anterior puncture (Aa) between A l and A 2 . Posterior setae 4 (P lf P 2 ) 
and posterior punctures (Pa, Pb) near the middle of the head; P x on the level with 
adfrontal puncture 5 ; P 2 posterior to Adf 2 . Pa equidistant from P lf A 3 and the lateral 
seta (Li), remote from anterior group, nearly on the level with P t ; lateral seta (Li) 
remote from A 3 , nearly on the level of Pb; lateral puncture (La) posteroventral to the 
seta, remote. Of the ocellar setae (O x , 0 2 , 0 3 ), 6 * 8 O t is equidistant from and lateral to 
ocelli ii and iii, 0 2 is closely approximate and postero ventral to ocellus i; 0 3 is directly 
ventral and remote from 0 2 , on a line with ocelli v and vi; ocellar puncture (Oa) 
between 0 3 and ocellus vi, approximate to latter. Subocellar setae (Sc^, So 2 , So 3 ) 
triangularly placed, nearly equidistant; subocellar puncture (Soa) between and equi¬ 
distant from So 2 and So 3 . Genal seta (G t ) and puncture (Ga) both present; puncture 
anterior to seta. 
Labrum (PI. 10, /, J) with median incision rather deep and evenly rounded. The 
three lateral setae (La x , La 2 , La 3 ) close to edge, La x and La 2 closely approximate, 
La 3 remote; median setae (Mj, M 2 , M 3 ) in the usual Micro arrangement with M 2 lateral 
and slightly posterior to M x ; M 3 close to anterior margin on a line with La 3 ; M l and 
M 2 on a line respectively with La 2 and La t . 
Epipharyngeal shield (ES) merely a slight chitinization of the edge of the median 
incision; epipharyngeal setae narrow plates, triangularly grouped near anterior mar¬ 
gin. Epipharyngeal rods not discernible in the labrum proper, only represented by 
their posterior projections, which are rather well developed. 
Mandibles (PI. 10, D-G) strong, as broad as long, with four stout, rather short teeth; 
the three lower ones pointed; the upper blunt; a fifth lower tooth is slightly indicated 
on the underside; one long and one shorter seta on upper side near lower edge. 
Labium and maxillae normal (PI. 9, C). 
Antennae (PI. 10, H) four-jointed, with second joint considerably longer than joint 
3, longer than broad; the longer seta longer than the entire antenna; papillae mi¬ 
nute, much shorter than third joint. 
Three pairs of normal thoracic feet; four pairs of abdominal prolegs with crotches 
of uniform size in an incomplete circle, opening outwardly (PI. 10, K); anal prolegs 
with a transverse row of uniordinal hooks. 
The arrangement of the body setae is normal, as shown in Plate 11 , A, B. It differs 
from that of Gelechia in having the three setae on prespiracular plate of prothorax 
nearly equidistant, while in Gelechia the posterior seta is farther separated from the 
two others than they are from each other, and in having the three setae vii of the 
proleg-bearing abdominal segments* arranged in a triangle, not in a line as in 
Gelechia. 
1 The nomenclature of the head setae has been adopted from Heinrich (39) with certain minor modifica¬ 
tions, noted in the following footnotes and concurred in by Mr. Heinrich. 
2 So-called “secondary punctures" of Heinrich, sometimes bearing minute setae. 
2 Anterodorsal setae of Heinrich. 
4 Posterodorsal setae of Heinrich. 
6 The term “on the level with” is used in these descriptions as the head setae are seen in frontal pro¬ 
jection (fig. 2, A)\ anything above a level is termed “posterior" and anything below is termed 
“anterior.” 
8 Heinrich’s numbering reversed.
