[Vol. XV, No. 8, 
3d, 1905. The specimens all belong to the variety M. inermis 
Dali, as recognized by Distant. A large series of this species from 
British Guiana shows about every gradation from the strongly 
spinous to the non-spinous pronotal angles. 
Mormidea pictiventris Stal. 
A fine series from Guatemala: Puerto Barrios, March 3d, 
1905. 
Euschistus crenator Fabricius. 
A full series, evidently rather abundant in Central America. 
Guatemala: Gualan, Feb. 15th; Los Amates, Feb. 25th; Puerto 
Barrios, March 3d and 14th, 1905. Honduras: San Pedro, 
Feb. 21st to March Sth, 1905. This is a rather variable species. 
Three specimens from Gualan have the humeral angles less 
produced and not acutely angled; the lateral border of pronotum 
denticulate anteriorly, smooth posteriorly (without any denticula- 
tions); scutellum at apex with a very narrow whitish border. 
Proxys albo-punctulatus Palisot de Beauvois. 
Two specimens: Santa Lucia, Guatemala, Feb. 2d, 1905. 
Proxys victor Fabricius. 
Four specimens from Guatemala: Santa Lucia, Feb. 2d, and 
Los Amates; Feb. 18th and 25th, 1905. 
Proxys punctulatus Palisot de Beauvois. 
Two specimens: San Pedro, Honduras, Feb. 21st, 1905. 
The three above species belonging to this genus are closely re¬ 
lated. The rather arbitrary separation on color of legs seems 
barely warranted, but we have followed Stal and Distant in recog¬ 
nizing them. 
Thyanta perditor Fabricius. 
Three specimens from Guatemala: Gualan, Jan. 14th, Los 
Amates; Feb. 18th, and Puerto Barrios, March 3d, 1905. 
Nezara marginata Palisot de Beauvois. 
Two specimens: Los Amates, Guatemala, Jan. Kith, 1905. 
Banasa albo-apicata Stal. 
One specimen: Los Amates, Guatemala, Feb. 18th, 1905. 
Hitherto recorded for Central America (Honduras) on the authori¬ 
ty of Stal and its occurrence seems rather rare. 
Piezosternum subulatum Thumb. 
One specimen, taken at Morales, Guatemala, March Sth, 
1905. This species has been recorded for Panama, Columbia, 
and Antilles but not for Guatemala. 
Edessa taurina Stal. 
One specimen: Puerto Barrios, Guatemala, March 3d, 1905.
