Key West, Florida, VII, 7, 1912, (Rehn and Hebard; under boards in wood shed, 

 many immature examples under nearby boards on ground), 15 cf, 28 9 ,^-^ 10 juv., 

 [Hebard Cln. and A. N. S. P.]; XII, 28, 1909, (Harris), i cf, [U. S. X. M.]. 



Subfamily CORYDIINAE 



The Corydiinae and Polyphaginae share the distinctive character 

 of having the wings, when present, with anal field plane, not folding 

 fan-wise. 



The following characters are considered diagnostic for the 

 present subfamily. Head globose; ocellar areas never strongly 

 defined ; ocelli absent or very small, then with surfaces convex. 

 Pronotum and tegmina (when present, except in hyaline portions 

 found in some genera) thickly covered with hairs. Tegmina, 

 when present, opaque, transparent, or partially opaque and par- 

 tially hyaline; when opaque, with venation very weakly defined. 

 Female subgcnital plate simple, or valvular, with basal margins of 

 valves forming a deep, acute-angulate cmargination.^''*' Limbs 

 with ventral margins of cephalic and median femora unarmed, 

 except sometimes distad on ventro-cephalic margins of cephalic 

 femora and both margins of median femora. Tarsi with or without 

 small pulvilli. Arolia present or absent. 



HOLOCOMPSA Burmeister 

 1838. Ilolflcompsa Burmeister, Handb. Ent., ii, abth., ii, pt. i, p. 491. 



This genus is very widely separated from any other found in the 

 regions here considered. Three species were originally included, 

 of these cyanea and coUaris are synonyms of nitidida. 



Genotype: C[orydia {Holoconipsa) ] collar is Burmeister = //o/o- 

 compsa nitidida {B[latta] nitidida) (Fabricius), selected by Kirby, 

 in 1904.^^1 



The two adult Yucatan males differ from any others in the greater extent of the l)ufT 

 tegminal markings. In these specimens the entire anal field is buff, this color breaking 

 through meso-laterad into the broad buff marking bordering the costal margin. These 

 features represent nothing more than color variation, but give the insects a distinctive 

 facies. The British Honduras specimen shows this condition, but the pale areas are less 

 extensive. 



'-' A number of lice are present on many of these specimens. 



23" This general type of subgenilal plate is found in the Ectobiinac in Anaplecta and in 

 the Polyphaginae in Homoeogamia. See plate YIII, fig. 1 1.
