of forewing) that I hesitate to sink the name completely. 

 It is possible that hulstii CockereU and quadricolorella 

 stand for the same form (types of both are from Las 

 Cruces and have clear white hind wings) ; but the type 

 of the former (9) is unrecognizable and the name may 

 very well be left where it is. 



Dyar's t5rpe is a male and not a female as he stated 

 in his description. 



476. Laetilia coccidivora cardini Dyar 



FiGiTBEs 505, 998 

 Laetilia cardini Dyar, Ins. Insc. Menstr., vol. 6, p. 139, 1918. 



Not distinguishable from small specimens of tj^jical 

 coeddivora except that the hind wing is somewhat 

 darker. In addition to the female type I have before 

 me another female from the type locality and three 

 males and eight females from Orlando, Fla. The 

 Florida specimens were reared from larvae feeding on 

 mealy bugs on grapefruit. 



The female genitaha differ only in their smaller size 

 from genitalia of normal coccidivora, but even in this 

 detail do not differ from equally small examples of 

 coccidivora. The male genitalia show apex of uncus 

 rather more pointed and the posterior horns of apical 

 process of gnathos more widely spaced than those of 

 typical coccidivora. However there is considerable 

 variability in these structures in coccidivora and the 

 differences exhibited by the male of cardini may not be 

 constant. In my opinion they do not justify more than 

 racial separaton. 



Type locality: Santiago de las Vegas, Cuba (type 

 inUSNM). 



Food: Mealy bugs. 



Distribution: Cuba: Havana, Santiago de las 

 Vegas. United States: Florida, Orlando (June). 



477. Laetilia obscura Dyar 

 FiGUEES 506, 1000 

 Laetilia obscura Dyar, Ins. Insc. Menstr., vol. 6, p. 140, 1018. 



Brownish fUscous with a sparse scattering of whitish 

 scales on head, thorax, and subcostal area of forewing. 

 Usual transverse markings on forewing nearly obsolete; 

 antemedial line very faint, straight, shaded outwardly 

 towards costa by dark brown; sub terminal line a mere 

 trace; discal dot obscure; cilia very little paler than 

 ground color. Hind wing pale smoky fuscous, darkened 

 outwardly and with blackish brown terminal margin; 

 cilia slightly paler with dark basal band. Alar expanse, 

 9-11 mm. 



Male genitalia similar to those of coccidivora cardini 

 but with posterior horns of gnathos more widely 

 spaced. Female genitaha with signum similar to but 

 weaker and narrower than that of coccidivora or any of 

 its varieties. 



Type locality: Santiago de las Vegas, Cuba (type 

 inUSNM). 



Food: Presumably Coccidae (type series apparently 

 reared but without labels to indicate food or dates of 

 emergence) . 



Distribution: Cuba. 



Represented in the National Collection only by 

 specimens from the type locality. It may prove to be 

 merely a dark, suffused race of coccidivora; but the 

 uniformly dark color, the almost complete obliteration 

 of the usual transverse markings, and the much narrower 

 signum suggest a distinct species. 



478. Laetilia portoricensis Dyar

Laetilia portoricensis Dyar, Ins. Insc. Menstr., vol. 3, p. 62,

 No. 1, p. 479, 1936. 



Palpi, face, head, and thorax pale brownish fuscous 

 with a few white scales on inner side of palpus and on 

 face. Forewing pale brownish fuscous with area 

 between costa and upper vein of cell and antemedial 

 and sub terminal lines white; on this white area a 

 rather conspicuous midcostal, blackish brown dash; 

 basal area paler than ground color, whitish toward 

 costa; transverse pale lines obscure, indicated chiefly 

 by their dark outer borders ; antemedial liae slightly 

 angled at ceU, bordered outwardly by blackish brown 

 which is conspicuous on costa and forms a patch at the 

 cell; subterminal Hne outcurved between veins 2 and 5, 

 rather broadly bordered with blackish brown towards 

 costa; a blacMsh brown discal dot at upper outer angle 

 of cell; more or less blackish shading along submedian 

 fold and upper vein of cell; a few indistinct dark spots 

 on pale termen between the veins; cilia concolorous 

 with pale terminal margin. Hind wing pale smoky 

 brown; terminal margin dark brown; cilia sordid 

 whitish with dark basal band. Alar expanse, 10-13 



TTITn , 



Male genitaha with gnathos terminating in a pair of 

 rather weakly sclerotized, liplike lobes without posterior 

 horns; imcus rather broad but laterally folded, apical 

 margin roxinded; penis without cornuti. Female geni- 

 talia with signum a rather small, nearly round, sclero- 

 tized, scobinate disk; bursa copulatrix, except for 

 signum and area immediately adjoining it, smooth; 

 vinculum long. 



Type locality: RIo Piedras, Puerto Rico (type in 

 USNM). 



Food : Saissetia oleae, Lecanium sp. 



Distribution: Puerto Rico: RIo Piedras (Nov.), 

 Bayam6n (Aug.), Comerio (Aug.). 



The genitaha and the midcostal dark dash on fore- 

 wing readily distinguish this species from anything else 

 in the genus. Dyar described it as "gray," but the 

 ground color and general effect, except for the contrasted 

 whitish subcostal area, is more brown than gray.
