the genus Brachytoma of "Westwood. The genera belonging to the 

 sub-family to which these species belong may be briefly characterized 

 as follows :* 



A. Antennae 10- 11-jointed, labial palpi l-jointed, maxillary 3-jointed... 



Decameria^ Lep. 

 1 B. Antennae with more than 11 joints. 



1. The antennae with more than 13 joints, flabellate in the ^ , maxillary palpi 4-, 



labial 3-jointed ; 2nd cubital cellule usually receiving both recurrent 

 uervures, appendicular cellule in hind wings very small... 



Type, L. tropicus, Norton. Lophyroides, g. n. 



2. The antennae 13-jointed, maxillary palpi 2-, labial l-jointed ; 2nd cubital 



cellule usually receiving only one recurrent nervure, appendicular cellule 

 in hind wings large Ferreyia, Brulle. 



The genus Camptoprium, Spinola, is no doubt identical with De- 

 camerin ; but Spinola describes the palpi as long filiform and 6- and 

 4-jointed. I suspect, however, that this statement is erroneous. 



Perreyia (?) miomala, Kirby, List of Hym., i, p. 90, pi. vi, fig. 14, 

 is evidently identical with Lophyroides tropicus, Norton. What Mr. 

 Kirby (I. c. pi. vi) figures as the ^ of Perreyia compta, Norton, is, so 

 far as I can make out from the figure, identical with a species I have 

 described in the " Biologia Centrali- Americana " under the name of 

 Lopliyroicles riijicollis. As Mr. Kirby appears (I. c. p. 90) to doubt 

 if Norton had really males of P. compta, I may mention that all his 

 specimens were males. I have examined them through the kindness 

 of Dr. Henri de Saussure. 



Cephalocera (?) calcar, Norton, Trans. Amer. Ent. Soc, i, p. 51, 

 belongs to the genus Lohoceras, Kirby. 



Nematus hetularius, Htg., Blattw., 192, 17, = erytlirog aster, Thoms., 

 nee Norton. Before I was aware of the identity of erythroqaster with 

 hetularius, I named it crassiventris (Ent. Mo. Mag., xiv, 267), and 

 Mr. Kirby (List of Hymen., i, p. 132) has named it luteogaster. 



Nematus conjugatus, Dbm., S. E. Z , 1848, p. 177 ; Thorns., Opus. 

 Ent., 023, 19. This species is British ; I have found the larvae in 

 Clydesdale. 



Nematus consobrinus, Yoll., Tijd. Ent., xvi, p. 236, pi. x (1871),= 

 N umhrinus, Br. & Zad., Schr. Ges. Konig., xvi, p. 84 (1876). The 

 late Prof. Zaddach confirmed this determination a short time before 

 his death. 



Nematus varius, Andre, Species d. Hymen., i, 193, = N pallescens, 

 Htg., Cameron, Eauna of Scot., Hymen., pt. 1, p. 40.
