15. Buenoa pallipes (Fabricius) Champion. 



I have received a long series taken in the Rio Maria Aguilar 

 in January. In Biologia Centrali-Americana it is given from 

 Vera Cruz in Mexico to Darien in Panama. This is now re- 

 corded for the first time from Costa Rica. 



16. Buenoa carinatus Champion. 



One example from San Jose. This does not attain the 

 smallest dimensions given by Champion for his species, but in 

 other respects it answers to the description. It is not recorded 

 from further south than Guatemala and Honduras. 



17. Rhagovelia crassipes Champion. 



There is in this lot of insects a female from Vista del Mar, 

 taken in March, which is the first record for Costa Rica. The 

 types were from Panama, where they were found in plenty in 

 two localities. 



18. Rhagovelia armata Burmeister. 



Two females were received from San Jose. Champion re- 

 cords it from Mexico, fide Burmeister and Signoret, but evi- 

 dently did not possess it himself. 



19. Rhagovelia spinigera Champion. 



A long series of this form came to hand from Rio Maria 

 Aguilar in January and San Jose in August. This species 

 was described by Champion from one female example taken in 

 Guatemala. Consequently, this is the first record outside of 

 the published locality. 



20. Microvelia n. sp.? 



This is apparently an undescribed form, of which numbers 

 were taken at San Jose in January. 



21. Gerris cariniventris Champion. 



A good number of this species, both winged males and fe- 

 males and one apterous female were taken at Rio Maria Agui- 

 lar in January and May. This is apparently common and 

 numerous from Mexico down. 



22. Gerris (tenagogonus) opaca Champion. 



Two specimens from the Rio Surubres in February. Re- 

 corded by Champion as plentiful in Bugaba, Panama, the type 

 locality. Both this and the following are listed under the 

 generic synonym Limnometra.
