Subfamily I 'V K'AfM.'I X . K. 



Genus PYRAGRA Serville. 



1. FUSCATA Serville. 



CostaRica. SanCarlos (Schild-Burgdorf ) . Fragment. [See Rehn, 

 1903 2 , p. 2!)!).] 



British Honduras. — Bengue Viejo, July, 1904 (W. A. Stanton i. 



I also refer here, with a little hesitation, I John's type of Echinopsalis 

 brevibractea [1903 2 , p. 300], taken by G. II. Osborn in Mexico, Motzo- 

 rongo, Veracruz, January, 1892. (Cat. No. 7078.) The specimen 

 is immature, and consequently the specific characters are not prop- 

 erly developed. But it has a superficial appearance of this species or 

 else of the P. dohrni. 



P. fuscata is recorded from Mexico by de Bormans, Dohrn, and 

 Burr. 



I agree with Rehn in restoring Serville's name for this species. 



2. DOHRNI Scudder. ■ 



Peru. — Piches and Perene valleys, 2,()()() to 3,000 feet. (Cat. No. 

 8171.) 



This is Rehn's type of Pygidicrana peruviana [1905 1 , p. 501], a 

 female, so that name consequently falls as a synonym. 



3. BUSCKI Caudell. 



Cuba. — Baracoa, October 14, 1901 (Busck), one male. Type of 

 Caudell [1007', ]>. 166]. (Cat. No. 10288.) 



Jamaica. — "In rotten palm," March 18, 1007 (W. Johnston). 



This is a good species; it is related to P. paraguayensis Borelli 

 and P. brunnea Burr, differing from both in the nearly glabrous body 

 and absence of keels on the upper surface of the last dorsal segment. 



This group differs from that of P. fuscata in the transverse pro- 

 notuni. 



ARTHROEDETUS BARBERI Caudell. 



Guatemala — Poloehic River (II. S. Barber). (Cat. No. 10366.) 

 Type of Caudell [1907 2 , p. 171]. 



The apparently anomalous features of this creature are due to the 

 immaturity of the specimen; the very long third antennal segment 

 is a well-known characteristic of nymphs and larvae; Terry (100.")) 

 has shown that the apical segments all grow out of the third, which is 

 consequently extra long in immature specimens. The features of the 

 thorax, are explainable in the same way. 



It is impossible to say to what species it should be referred; very 

 likely to Pyragra fuscata Serville, or some ally. 



Genus ECHINOPSALIS Bormans. 

 1. GUTTATA Bormans. 



Paraiso, Canal Zone (P. B. Preston i. 



A single female, with the abdomen broken oil and cemented on again 

 upside down.
