PINK BOLLWORM OF COTTON IN MEXICO. 
61 
Frontal punctures (Fa) close together, anterior to frontal setae (FJ; distance between 
punctures less than distance between puncture (Fa) and setae (F x ); frontal setae (F x ) 
and adfrontal setae (Adf x and Adf ? ) 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 8 (x, y, and z). 9 
Anterior setae 10 (A x , A 2 , A 3 ) in a slightly obtuse angle; 
than A 2 and A 3 ; anterior puncture (Aa) between A x and A 
A t and A 2 closer together 
Posterior setae 11 (P v P 2 ) 
and posterior punctures (Pa, Pb) near the middle of the head; T l on the level with 
B

adfrontal puncture 12 ; P 2 posterior to Adf 2 . Pa equidistant from P l7 A 3 and the lateral 
seta (L x ) remote from the anterior group, nearly on the level with P x ; lateral seta (Lj) 
remote from A 3 , nearly on the level of Pb ; lateral puncture (La) posteroventral to the 
seta, remote. Of the ocellar setae (O x , 2 , 3 ), 13 O x is equidistant from and lateral to 
ocelli ii and iii, 2 is closely approximate and posteroventral to ocellus i; 3 is directly 
ventral and remote from 2 , on a line with ocelli v and vi; ocellar puncture (Oa) be- 
tween 3 and ocellus vi, approximate to latter. Subocellar setae (Soj, So 2 , So 3 ) 
triangularly placed, nearly equidistant; subocellar puncture (Soa) between and equi- 
distant from So 2 and So 3 . Genal seta (G x ) and puncture (Ga) both present; puncture 
anterior to seta. 
Labrum (fig. 5, F, G) with median incision rather deep and evenly rounded. The 
three lateral setae (La l5 La 2 , La 3 ) close to edge, La t and La 2 closely approximate, 
La 3 remote; median setae (M 1; M 2 , M 3 ) in the usual Micro arrangement with M 2 lateral 
and slightly posterior to M t ; M 3 close to anterior margin on a line with La 3 ; M x and 
M 2 on a line respectively with La 2 and La x . 
8 The nomenclature of the head seta? has been adopted from Heinrich [Heinrich, Carl. On the taxonomic 
value of some larval characters in the Lepidoptera. In Proc. Ent. Soc. Wash., v. 18, no. 3, p. 154-164, illus. 
1916.] with certain minor modifications, noted in the following footnotes and concurred in by Mr. Heinrich. 
9 So-called "secondary punctures" of Heinrich, sometimes bearing minute setae. 
10 Anterodorsal setae of Heinrich. 
11 Posterodorsal setae of Heinrich. 
12 The term "on the level with " is used in these descriptions as the head setae are seen in frontal projec- 
tionfPl. V, A); anything above a level is termed "posterior" and anything below is termed "anterior." 
i 3 Heinrich's numbering reversed.
