Goerita Ross 



Goerita Ross (1938^, p. 171). Genotype, by 

 original designation: Goerita semata Ross. 



Not known from Illinois. The only 

 known eastern species, semata, has not been 

 recorded east of the Allegheny ranges. The 

 male genitalia are distinctive, fig. 878. 



Pseudogoera Carpenter 



Pseiidogoera Carpenter (1933, p. 37). Geno- 

 type, by original description: Pseudogoera 

 singularis Carpenter. 



This genus is known only from the type 

 series of the genotype, described from North 



Fig. 879. — Pseudogoera singularis, male 

 genitalia. A, lateral aspect; B, dorsal aspect. 



Carolina. The distinctive male genitalia are 

 illustrated in fig. 879. 



LEPIDOSTOMATIDAE 



In this family the maxillary palpi of the 

 females are five segmented, and those of 

 the males vary from three to a curiously 

 modified structure which may appear only 

 one segmented. As here defined it includes 

 only two Nearctic genera, Lepidostoma and 

 Theliopsyche. The larvae are known for 

 many species of Lepidostoma; these bear a 

 striking superficial resemblance to many 

 genera of Limnephilidae but may be readily 

 separated by the antennae, which are close 

 to the eye, and by lacking a dorsal spacing 



hump on the first abdominal segment. The 

 larvae and pupae of Theliopsyche are un- 

 known.
