discocubital cell, etc., are alike in both, but Cameron's plate 

 shows that his specimens had two maculae. This is appar- 

 ently only a variation and they probably belong with this 

 species, but certainly are not E. mexicanus Cress. 



Nothing is known of the life history, habits, or hosts of 

 this species. • 



Enicospilus fernaldi n. sp.* 



Flavo-fulvous, sericeous, vertex black, mesonotutn with three more or 

 less distinct fuscous stripes, abdomen beyond the fourth segment dark 

 fuscous or black, stigma fulvous, discocubital cell with two -macules, the 

 larger with a more or less distinct appendix. 



Length, 12-18 mm. ; wing, 10-12 mm. ; spread, 21-26 mm. ; antennse, 

 12-18 mm. 



Head flavous, vertex and antennae fuscous ; eyes large, emarginate ; 

 clypeal foveae distinct. 



Thorax of general color, fulvous, more or less tinged with flavous, and 

 in one specimen almost entirely of a greenish yellow ; pectus, and rarely 

 thescutellum, flavous ; mesonotum with three more or less distinct fusc- 

 ous stripes ; scutellum usually flavous ; metathorax with weak anterior 

 transverse carina, in front of which it is smooth, behind densely and 

 finely rugose ; wings hyaline, iridescent, stigma flavous, discocubital 

 cell with two maculse, the larger with a more or less distinct short ap- 

 pendix, the smaller erect crecentic, at the other end of the glabrous 

 area ; nervulus antef ureal to interstitial, nervellus broken well below 

 the middle ; first recurrent vein one-half the length of the third. 



Abdomen with the four basal segments fulvous, beyond the fourth 

 segment black ; the two basal segments linear, of about equal length. 



Described from two 9 and one c? specimens. 



Cotypes. — Two 9 's and one cf in U. S. National Museum 

 from San Francisco Mountains, Santo Domingo. 



This species resembles E. flavus in color but is smaller. 

 The antennas and apex of the abdomen are black, not fuscous 

 as in flavus ; the maculae also differ in shape. It does not 

 seem to be E. bicolor, for in that species the wings are fiavo- 

 hyaline, and the amount of flavous on the abdomen differs. 



Distribution. — San Francisco Mountains, Santo Domingo, 

 September, 1905. 



Nothing is known of the life history and habits.
