 Three New Genera. 

 Lanaphora, gen. nov. . 



Head narrower than thorax; ver'tex quadrate, the base as 

 broad as the length, apex half the base, a small carina along base 

 and apex; face nart-ow, sides straight, apex about twice the width 

 of base, a small simple carina down middle; the lateral carinae of 

 vertex and face developed into deep keels, diminishing in sizie 

 towards the apex of face; clypeus nearly as long as face, tricarinate. 

 Antennae longer than face and clypeus together, joints subequal in 

 length, arista apical and long; first joint narrow, slightly flattened, 

 second joint terete with distinct sense organs surrounded with 

 minute hairs; eyes wide with deep antennal emargination on lower 

 edge. Pronotum very slightly emarginate posteriorly, tricarinate, 

 lateral carinse straight or very slightly convergingly curved, reaching, 

 hind margin. Mesonotum tricarinate. First joint of hind tarsus 

 equal to the other two together, spur cultrate, thick, inner surface 

 concave, a minute tooth at apex; no teeth on hind margin, only 

 minute .fine hairs; one basal and one median spine on hind tibiae, 

 five small apical spines. Tegmina pointed at apex, radia not 

 touching media, a short radial cross-vein present, median with two 

 sectors, cubitus touching radia at base of first sector. 



This genus differs from Purohita in the subequal joints of the 

 antennae, the basal one of which is not foliaceous, and the lateral 

 carinse of the face being deeper. If we disregard the spur it comes, 

 along with Purohita, next to Sparnia. 



Type — L. bakeri. 



Lanaphora bakeri, sp n 



cf Light yellow or yellowish white, darker on face, clypeus, 

 coxae and basal portion of abdominal segments; some darker brown 

 spots on lateral keels of vertex and face, antennae, especially a ring 

 at base of second joint, and two small irregular rings on tibiae;-
