and abdomen light brown. Length 6.5 mm. ; f orewing length 4.2 mm., 

 breadth 1.1 mm. 



Head (fig. 84) with eyes very large, strongly inflated; interspace 

 slightly narrower than an eye width ; sides behind eyes short, slightly 

 shorter than an eye length, straight, strongly convergent, abruptly 

 rounded behind; caudal margin transverse, weakly arcuate. Man- 

 dibles moderate sized, sharply pointed, inner sides evenly emarginated. 

 Antennae strongly pigmented throughout. 



Wings moderately broad, light brown; hyaline stripes narrow, 

 sharply defined. Three cross veins present between Ki and R2+3 in 

 forewing and four in this position in hindwing. Anal vein well 

 defined basally in both wings, united by a cross vein to Cuib. 



Terminalia (figs. 87, 88) similar to those of davisi with the following 

 differences : JNIedian cleft of tenth tergite broader and with differences 

 in margins; 10 LP narrower, more strongly tapered apically; 10 RP 

 broader, with apical claw not extending beyond outer margin of proc- 

 ess. Process of hypandrium (HP) broader; with left apical angle 

 produced as a prominent, thumblike nodule, which is densely 

 echinulate. 



Female (in alcohol). — Head, mesothorax, hindlegs, and abdomen 

 reddish brown; antennae and prothorax light brown. Body length 

 8.5 mm. Head circular in outline, without dorsal pattern. Eighth 

 sternite uniformly pigmented throughout. Ninth sternite with an 

 obtuse, membranous, mediobasal angle similar to texana (Ross, 1940b, 

 fig. 38), but more extensive. 



Holotype and allotype. — Male and female, respectively, on slides, 

 U.S.N.M. No. 56046. 



Type data. — Collected at Matamoros, Mexico, in plant quarantine in 

 a cargo of pineapples shipped from Isla, Veracruz, Mexico, June 15, 

 1940, by Lispectors Anderson, Parnell, and Reagan. 



Paratype. — Topotypic female, deposited in the writer's collection. 



Remarks. — C. (C.) nodulosa is closely related to davisi from the 

 same state of Mexico. It may be separated by its much larger, in- 

 flated eyes, evenly emarginated mandibles, paler wings with cross 

 veins, and particularly by the presence of the prominent, echinulate 

 nodule of the left apical angle of the hypandrium process (HP).
