abdomen shining; stigma broadest at basal third; third intercubitus 

 opposite end of stigma; third cubital longer than first and second on 

 the radius and distinctly longer than the second on cubitus, receiv- 

 ing second recurrent at basal sixth. Rufo-testaceous ; head, apical 

 five tergites and apical sternite black; maxillary palpi testaceous; 

 color of thorax rufo-testaceous of abdomen more yellowish; legs color 

 of thorax; wings yellowish hyaline, dusky beyond end of stigma; 

 venation brown darker apically; costa and stigma yellowish; head 

 and thorax with short blackish hair. 



In the paratype the antennae are 17-jointed, the thorax and ab- 

 domen are the same color and the black at the apex of the abdomen 

 is indented medianly with yellow; the third cubital is somewhat 

 shorter. 



Type locality. — Sao Paulo, Brazil. 



Described from one female type collected November 20, 1912, by 

 G. E. Bryant, and one female paratype labeled " Brazil, Coll. Konow." 2 



Type. — In the British Musuem of Natural History, London. 



Paratype. — In the Deutschen Entomologischen Museums, Berlin. 



Genus PERREYIA Brulle. 



It is possible that I am wrong in using this genus as restricted by 

 Cameron, but this can only be decided by a study of genotypes. 

 The species placed in this genus can be divided into smaller groups by 

 characters on the antenna. One of these groups (the one to which 

 compta Norton belongs) has a close resemblance to Decameria and it 

 may be found advisable to place it nearer to it. 



PERREYIA COMPTA Norton. 



A single male collected by Frederick Knab at Cordoba, Mexico, 

 June 14, is in the United States National Museum. 



PERREYIA UNICOLOR, new species. 



Should easily be distinguished by small size, and entirely pale head. 



Male. — Length, 5.5 mm.; length of anterior wing, 5.5 mm.; length 

 of antenna, 3.5 mm. Slender, apex of abdomen narrowed; head 

 rather small, strongly receding behind eyes; labrum as long as clypeus, 

 emarginate apically; clypeus, short, flat, truncate apically; supra- 

 clypeal area very gently convex; distance between the eyes at the 

 clypeus distinctly greater than the length of an eye; a distinct de- 

 pression below anterior ocellus so frons look to have two low rounded 

 protruberances; antennal furrows complete, though poorly defined 

 behind ocelli; postocellar furrow obsolete; postocellar line distinctly 



5 Since the above was written I have seen a single female (rnetatype) from Sao Paulo, Brazil, collected 

 August, 1905. This was sent by H. Luederwaldt, of Museu Paulista, and the specimen returned to 

 that museum. This specimen has 18-jointed antenna and the third cubital cell is short as in the 

 paratype.
