receiving the first recurrent before the middle ; third subobsolete ; stigma fus- 

 cous, elongate lanceolate, its apical half lying within the marginal cell; legs 

 dark honey yellow, thinly clothed with yellowish hairs ; trochanters and coxae 

 pale yellow ; abdomen elongate ovate, shining, finely and remotely punctured ;

 Length 7 mm. ; expanse of wings 11 mm. 



Hab.— Texas. Mr. Belfrage. 



This species is closely allied to P. unicolor Cresson, but may be 

 distinguished by the absence of the thoracic lines and the distinct 

 fuscous lateral carinae of the second abdominal segment. 



Genus 5, CHYPHOTES nov. gen. 



Females apterous ; mandibles arcuate, with small tooth before the 

 apex ; maxillary palpi 4-jointed, the labial palpi 2-jointed, short ; 

 eyes roundly ovate, polished ; thorax divided in two parts, prothorax 

 short and convex, meso- and metathorax in one, globose ; basal joint 

 of anterior tarsus deeply emarginate within ; femora and tibiae more 

 robust than in Photopsis; abdomen petiolate, the petiole slender and 

 cylindrical to base, suddenly and greatly dilated at apex, where it is 

 subglobose and sessile with the second segment. 



Figs. 19 and 20 give a dorsal and lateral view. 



This remarkable form may possibly prove to be the female of 

 Photopsis.
