with a very fine bvit irregular pattern of lines and l)lotches of van- 

 dyke brown covering the surface, a distinct median hour-glass shaped 

 figure present on the cephalic portion of the dorsum, and a median 

 caudal spot of velvety black. Tegmina with the darker color predom- 

 inating, but usually broken up and confined to veins, except an indistinct 

 proximal spot and several distinct but irregular spots on the apical half. 

 Cephalic and median femora distinctly annulate thrice with dark; 

 tibiae light with only one dark annulus. Caudal femora clouded 

 dorsad with vandyke brown, a clear light section along the ventral 

 carina of the pagina, the carina itself proximad alternately light 

 and dark, dark distad with the genicular region except the lobes light 

 and one light pregenicular annulus; caudal tibise light, dark distad. 



Measurements. 



Length of body, 22 mm. 



Length of pronotum 6.5 " 



Length of tegmen (approximately), 26.5 " 



Length of caudal femur, 2L5 " 



Length of ovipo-itor 9 " 



The type is unique. 

 Anabropsis costaricensis n. sp. 



Type: c? ; Carrillo, Costa Rica. [Hebard Collection.] 



Closely allied to A. aptera (Brunner) from Guatemala, but smaller 

 and with distinct subtruncate tegmina half as long as the abdomen 

 present. 



Size medium; form rather slender; surface glabrous. Head with the 

 occiput arched, median longitudinal carina extending to the fastigium 

 present ; fastigium similar to that of .4 . marmorata but not sulcate ; eyes 

 elongate reniform in basal outline, the elongation being ventrad, moder- 

 ately prominent when viewed from the dorsum ; palpi with the terminal 

 joint as A. marmorata, but penultimate joint much less compressed 

 and nearly cylindrical; antennae four times the length of the body. 

 Pronotum slightly less than three times the length of the head, dorsum 

 arcuate; cephalic margin truncate, caudal margin regularly arcuate, 

 lateral angles obsolete cephalad, distinct but notacutecaudad.extending 

 down along the caudal tranverse sulcus on the lateral lobes; median car- 

 ina present but weak ; transverse sulci two in number, cephalic immedi- 

 ately caudad of the cephalic inargin, caudal rather poorly defined dorsad 

 and more evident on the lobes where it has a ventro-cephalic trend ; 

 lateral lobes with the ventral and caudal margins from the dorso- 

 caudal margin to the ventro-cephalic angle one continuous and regular
