TYNACANTHA.—CYRTOCORIS. 43 
1. Tynacantha pulchricornis. (Tab. IV. fig. 3.)

Tynacantha pulchricornis, Stal, En. Hem. i. p. 56. 3. 
Hab. Mexico}. 
The specimen figured is from Mexico, and is in the collection of Dr. Signoret. 
Subfam. CY RTOCORIN A. 
Oxynotide, Dallas, List Hem. i. p. 74 (1851). 
Oxynotina, Stal, En. Hem. ii. p. 3 (1872). 
This subfamily contains but one genus, which comprises five known species, all confined 
to the Neotropical Region, of which but two have as yet been recorded from Central 
America. 
CYRTOCORIS. 
Cyrtocoris, White, Trans. Ent. Soc. Lond. iii. p. 89 (1842). 
Coptosoma, subg. Oxynotus, Lap. Ess. Hém. p. 74 (1832). 
Oxynotus, Dall. List Hem. i. p. 75 (1851); Stal, En. Hem. ii. p. 3 (1872). 
The name Oxynotus having been used in ornithology by Swainson in 1831, and by a 
less followed writer, Rafinesque, in Pisces in 1810, it is clearly right to follow Adam 
White, and use the name he substituted. This genus is of somewhat aberrant form 
from all the allied genera; the more or less hexagonal thorax and the scutellum, which 
does not cover the margins of the wings and is spinous on its disk, are well-marked 
characters by which it may be identified. The tarsi are two-jointed.

2. Cyrtocoris trigonus.

Hab. Merxico?.—Cotomsia?2; Braziu?, Minas Geraes?, Rio Janeiro 2. 
This species is included in the fauna from the record of Prof. Stal. We have neither 
received this insect from Central America, nor have I yet been able to examine a 
specimen. It should be readily distinguished from the last species by the character 
given by Germar, “ scutello tuberculo trigono, apice truncato.”
