Dec.,1914 Bulletin of the Brooklyn Entomological Society 91 



series of tests of the reactions in the Heteroptera. Observations 

 while collecting, especially with trap lights, are more abundant. 

 In this country the night flights of the larger Belostomatids are 

 known to all, even to non-entomologists. All our Lethocerus 

 come in great numbers to the electric-light globes, and are the 

 most familiar examples of positive phototropism. 



To published records are added the following Miridas which 

 flew into my light globe at White Plains, kindly determined by 

 Mr. Otto Heidemann : 



Trigonotyliis brevipes Jak. (3) Poeciloscytus basalts Reut. 



Trigonotylns confusiis Reut. Orfhotylns flavosparsns Sahib. 



A large trap light maintained at the Bussey Institution, Forest 

 Hills, Mass., has yielded the following : 



Reduvius personatus Linn. Psetidoxcnetus scuieUatus Uhler 



Lygus invitus Say Plagiognathiis fuscosiis Prov. 



Lygus pratensis Linn. Miris dolobratiis Linn. 



Four years ago in the plaza under the electric lights at INTonter- 

 rey, Mexico, I picked up these species. 



Pamera bilobata Say, one specimen. 



Lygaeus circumlitus Stal, 5 specimens, not heretofore recorded from 



Nuevo Leon. 

 Dysdercus obsciirattis Dist., heretofore known only from Guatemala and 



Costa Rica. 



To these are now added twentj'-six species taken in British 

 Guiana by Mr. J. M. Geddes, who writes that they all came to the 

 trap light while he was catching moths. Added to each is a brief 

 note as to its distribution, and it is worthy of recognition that in 

 many instances it extends notably the spread of the insect. All 

 were secured at the same place, Tumatumari, on the Rio Potaro. 



Loxa flavicollis Drury, a widespread species, recorded from Southern U. 



S. (Texas and Florida) to Rio Janeiro and the Antilles, as well as from 



this region. 

 Arocera apta Walker, known from British Guiana and recorded from 



Panama to Brazil. 

 Neodine macraspis Perty. Apparently known only from French Guiana. 

 Empicoris histrio Linn. Known from northern Brazil only. 

 Augocoris gomesii Burm., var. (rnconigra Kirk. A species known before 



from Mexico, Venezuela and Brazil, but not from British Guiana.
