144 AMERICAN HYMENOPTERA. 



Ereinotylus strainineus (Tasch.). 

 Ophion strainineus Taschenberg, Zeitchr. Ges. Nat., Vol. 46, p. 



431, n. 13, 9 , America borealis 1875. 



Dalla Torre, Cat. Hym., Ill, p. 199 1901. 



Allocamptus stratnineus Szepligeti, Gen. Ins., Hym., 34nie Fasc, 



pp. 22,36 1905. 



Stramineo-flavous ; sericeous, wings hyaline ; nervures straw-yellow ; 

 tnetaiwtufn very finely rugose. 



Length, 22 mm. 



Pale yellow, approaching ripe straw-color ; mesonotum with two 

 weak longitudinal carinee and metathorax with weak anterior trans- 

 verse carina and very finely rugose ; wings hyaline, base of radius 

 thickened and twice bent, discocubital nervure arcuate, nervellus 

 broken well below the middle. Apex of abdomen generally darker, 

 appearing somewhat spotted. In consequence of the finer wrinkling 

 of the mesonotum, the lighter color, complete transparent wings and 

 smaller size it appears more delicate than Eremotylus undulatus. 



I have not seen a specimen of this species, and can there- 

 fore give only a free translation of the original description. 

 Type. — Location unknown. 



This may prove to be a synonym of macrurus, but as I 

 have not been able to see the type or secure material I have 

 given the contents of the unfortunately incomplete original 

 description. I can find no other reference to this species 

 and nothing seems to be known of its life history, habits or 

 hosts. 



Eremotylus aiig'ulatus n. sp. 

 Plate. II, fig. 13. 



Fulvous ; wings hyaline or slightly fulvous ; radial vein angularly 

 broken 2 mm. from the stigma. 



Length, 38 to 45 mm. ; wing, 39 to 45 mm. ; spread, 80 to 92 mm. ; 

 antennae, 20 to 22 mm. 



Fulvous to fulvo-ferruginous, with head occasionally sulphur-yellow; 

 wings hyaline or slightly tinged with fulvous. 



This species resembles E. man-urtis, but the abdomen is 

 more slender, and it may be readily recognized by the angu- 

 larly broken radial vein. 



Described from three female cotypes from Porto Rico. 



Habits. — This species evidently preys upon a number of 

 lepidopterous larvae. The writer has recently bred it from 

 black wooly-bear caterpillars at Mayaguez, Porto Rico. The
