Divitiaca parvulella Barnes and McDunnough, Contributions, vol. 

 2, p. 183, 1913.— McDunnough, Checls; list. No. 6355, 1939. 



Averages smaller than simulella or ochrella. Ground 

 color and dark markings of forewing similar to those of 

 simulella but with a rather broad whitish band along 

 costa. Hind wings pale to dark smoky fuscous. Alar 

 expanse, 9-12 mm. 



Male genitalia with apical process of gnathos a long, 

 stout arm, swollen and abruptly hooked at the end. 

 Female genitaUa with bursa and ductus bursae smooth; 

 bursa trilobed (twice constricted near junction with 

 ductus bursae). 



Type locality: Marco, Fla. (type iu USNM). 



Food plant: Achyranthus ramosissima. 



Distribution: Florida, Marco (Apr.), Vero Beach 

 (Apr.), Key West (Apr.). 



Easily distinguished from other species in the genus 

 by the contrastingly white costa of forewing and the 

 peculiar development of gnathos and bursa. The Key 

 West specimens (1 g" and 3 9) were reared Apr. 7, 1945, 

 ia connection with the Special Survey of the Division of 

 Foreign Plant Quarantine, U. S. Department of Ari- 

 culture, from larvae feeding in the flowers oi Achyranthus. 

 They have given us our only food-plant record for the 

 genus. The male is slightly darker and somewhat more 

 strongly marked than either of the two males of the type 

 series. The reared females and a collected female from 

 Vero Beach are even darker, their hind wings being a 

 dark smoky fuscous. The larva lacks the sclerotized 

 rings about seta lib of mesothorax and seta III of 

 eighth abdominal segment characteristic of most phyci- 

 tine larvae. 



380. Divitiaca parvulella consociata, new race 



Similar to tjrpical parvuleUa except somewhat paler 

 and larger. The hind wing of the female is darker than 

 that of the male but not so dark as in the reared females 

 of parvulella from Key West, a difference of little or no 

 significance as between collected and reared specimens. 



The genitalia, male and female, are also shghtly larger 

 than those of Florida 'parvulella but not structurally 

 different. Alar expanse, 11-13.5 mm. 



Type locality: Valle de Medellin, Colombia (type 

 in USNM, 61365). 



Food plant: Unknown. 



Described from male type and one male and one 

 female paratype from the type locality, received from 

 F. L. Gallego M. under his No. Ill, and dated "January 

 1942." 



I name these examples with great reluctance and do 

 so only as a precautionary measure, since we have no 

 examples of Divitiaca from any intervening area between 

 Colombia and the United States. 



Genera 94-97: Macrorrhinia to Protasia 



[Venational division A. Forewing with 11 veins; 10 from cell, 8 

 and 9 stalked; 4 and 5 stalked; 2 and 3 from cell. Characters 

 otherwise as for previous group (^Divitiaca) .] 



94. Genus Macrorrhinia Ragonot 



Macrorrhinia Ragonot, N. Amer. Phycitidae, p. 13, 1887. (Type 

 of genus: Macrorrhinia aureofasciella Ragonot.)

 pt. 2, pp. xi, 190, 1901. — Hulst, Phycitidae of N. Amer., p. 

 190, 1890. 



Tongue weU developed. Antenna pubescent (cilia 

 about as long as width of shaft) ; in male a shallow sinus 

 with a very small tuft at base of shaft; in female simple. 

 Labial palpus porrect, downcurved ; long, extending at 

 least three times length of head beyond it. Maxillary 

 palpus minute, filiform. Forewing smooth; 11 veins; 

 vein 2 from slightly before angle of cell ; 3 from angle ; 

 4 and 5 short stalked; 6 from below upper angle of cell, 

 straight; 10 from cell, at base approximate to stem of 

 8-9; male without costal fold. Hind wing with vein 2 

 from close to angle of cell; 3 and 5 stalked; 7 aud 8 

 approximate or weakly anastomosed beyond cell; cell 

 slightly less than one-half the length of wing; discocel- 

 lular vein curved. Eighth abdominal segment of male 

 with a pair of short ventrolateral hair tufts and a lateral 

 pair of eversible lobes with long hair tufts (as in Diviti- 

 aca). 



Male genitalia with apical process of gnathos a stout 

 hook. Harpe with broadened cucullus; a transverse 

 sclerotized ridge extending from base of costa to lower 

 angle of cucullus. Anellus a slightly curved plate with 

 short, thick, lateral lobes. Aedeagus short, slender, 

 needlelike; penis without armature. Vinculum short 

 (as broad as long); extremity rounded. 



Female genitalia with bursa and ductus bursae mem- 

 branous throughout, except for a slight sclerotization of 

 the genital opening; bursa large, sausage shaped, with- 

 out signum; ductus bursae long, very slender for two- 

 thirds of its length, suddenly and considerably expanded 

 before junction with bursa ; ductus seminahs from ductus 

 bursae near genital opening. 



Ragonot (1888) proposed Dolichorrhinia as a new 

 name for Macrorrhinia Ragonot (1887) since the latter 

 was, in his opinion, a homonym, "resembling too much 

 the name Macrorhinus already employed twice." The 

 name is uncomfortably close to and much nearer a 

 homonym of Macrorrhina Berthold (1827); but under 

 our interpretation of the International Code the name 

 Macrorrhinia is homonymous with neither and will have 

 to replace Dolichorrhinia which lepidopterists since 

 Ragonot have been using for the genus.
