Anaulacomera digitata n. sp. 



Type: 9 ; San Jose, Costa Rica, 1,160 meters. At electric light. 

 July, 1904. (P. Biolley; No. 44.) [A. N. S. Phila.] 



Allied to A. furcata Brunner, but differing in the sulcate fastigium, 

 the undivided superior ramus of the radial vein, the absence of a dis- 

 thict angle on the dorsal margin of the ovipositor and the broader 

 tegmina. 



Size rather small; form moderately elongate. Head with the fasti- 

 gium narrow, the apex rounded and constricted proximad, moderately 

 but distinctly sulcate, the expanded proximal section with the margins 

 elevated, the lateral ridges being lost on the constriction ; facial fasti- 

 gium touching the fastigium of the vertex; eyes subglobose, quite 

 prominent; antennte reaching to the tips of the wings, proximal joint 

 large, equal to the space between the basal joints, flattened. Prono-

tum deplanate dorsad; cephalic margin truncato-emarginate, caudal 

 margin flattened arcuate, lateral angles narrowly rounded; lateral 

 lobes about as long as deep, caudal margin with the sinus rather broad 

 and deep, the margin arcuate from this to a point on the ventral section 

 which is obtuse-angulate, the cephalic margin being arcuato-emargin- 

 ate and the ventro-cephalic margin oblique. Mesosternum with the 

 lobes subtrigonal, each longer than broad. Metasternum with the 

 lobes rotundate, the medio-lateral section of their curve being flattened. 

 Tegmina about half again as long as the caudal femora, extremely 

 elongate-elliptical in outline, nearly four and a half times as long as 

 broad, the width except proximad and distad being subequal, costal 

 margin very gently arcuate, apex evenly rounded ; radial vein with the 

 two branches not distinctly subdivided, the division of the vein being
