﻿1869.] 23 



Head and thorax reddish-fulvous, the latter varied with black above. Antennce 

 yellow, obscurely annulated with fuscous, the apical portion totally blackish : 

 palpi piceous. Abdomen yellowish, clothed with concolorous hairs ; in the male 

 the last ventral segment is produced into a short, triangular, yellow, ciliated 

 borer-like appendages. Legs whitish ; anterior and intermediate tarsi annu- 

 lated with blackish. 



Wings whitish hyaline : anterior pair with numerous small rounded grey spots, 

 which are very conspicuous along the inner margin ; veins whitish, with minute 

 fuscous dots, from each of which arises a long erect blackish hair ; margins 

 longly ciliated j two sectors ; five veinlets in the inner gradate series, four in 

 the outer. 



I received three examples of this very minute and delicate species 

 from Mr. G. W. Belfrage, by whom they were taken in Bosque County, 

 Texas, in September.

 carindque media transversali, utrinque rufescenti, instructus. Ungues ad 

 basin valde dilatati, apicibus valde incurvatis. Alee latce, venis venulisque

Yellowish-green. Head with five small reddish dots, whereof one is placed on each 

 side of the vertex, one between the antennae, and one on each cheek. Palpi 

 fuscescent. Antennae yellowish at the base, afterwards brownish, the basal 

 joint very strongly inflated. Prothorax with a strongly raised median trans- 

 verse ridge, on each side of which is a small reddish dot ; the sides oblique in 

 front j a black spot at each angle above, and a black longitudinal line on each 

 side a little inferiorly. Meso- and meta-thorax unspotted. Abdomen greenish, 

 with a fuscous dot on each side of the base above. Legs whitish, the tarsi red- 

 dish-brown ; claws strongly dilated at the base, afterwards with the apices 

 greatly incurved. 



Wings broad, scarcely acute at the tips, hyaline and iridescent, veins and veinlets 

 all greenish, ciliated : the third cubital cellule in the anterior wings as in 0. 

 vulgaris. 



I possess one example, brought from St. Helena by Mr. Melliss, 

 who also collected two specimens of another Ghrysopa in the same 

 island, which do not seem sufficiently distinct from the abundant Euro- 

 pean G. vulgaris, already reported from Madeira and Mauritius.
