Genotype. — Lanta scotia new species. 



Generic Description. Size minute, form moderately broad, ellip- 

 tical; weakly convex surface polished, regularly but not thickly 

 clothed with silky, erect, pile. Head with occiput slightly roughened 

 and interocular area regularly and minutely pitted (from which 

 spring the minute hairs), but not decidedly and irregularly rugose 

 as in Melestora ; interocular space wider than that between antennal 

 sockets. Ocelli comparatively large, flat surfaces of ocellar areas 

 forming a decided angle with plane of interocellar area. Pronotum 

 elliptical, showing very slight flattening of the curvature of the 

 latero-cephalic portions; surface convex, the lateral portions show- 

 ing marked deflection; latero-caudal sulci of disk represented by 

 broad and well defined concave areas, which diverge cephalad, the 

 intervening section evenly and weakly convex. Tegmina coriace- 

 ous, bluntly elongate elliptical, but shorter and broader than in 

 the related genera, width nearly subequal through mesal half, apex 

 broadly rounded; numerous costal veins very strongly oblique; anal 

 field elongate pyriform, anal sulcus distinct; discoidal sectors longi- 

 tudinal or nearly so, connected by moderately well-developed cross- 

 veinlets, which form regularly rectangulate interspaces. Wings 

 fully developed, exceedingly delicate; costal veins thickened except 

 near base; interval between median and discoidal veins broad, with 

 transverse veinlets; ulnar vein bifurcate; intercalated triangle small 

 but distinct ; radiate field folding fan-wise. Dorsal surface of abdo- 

 men unspecialized. 



Cephalic femora with ventro-cephalic margin armed with a 

 single elongate spine, succeeded by a row of minute spiniform hairs, 

 terminated by one or two elongate spines. Other ventral femoral 

 margins, except the wholly unarmed ventro-caudal margin of the 

 cephalic femora, supplied with minute hairs but unarmed except 

 for a single elongate distal spine; median and caudal femora with 

 an elongate genicular spine. Caudal tarsus about three-quarters 

 as long as caudal tibia, succeeding joints three-quarters as long as 

 metatarsus, pilose but with ventral surfaces unspined. Pulvilli 

 absent. Arolia moderately large, extending to near apices of simple, 

 symmetrical tarsal claws. 



Lanta scotia'-' new species. Plate XIII, figures 7 and S. 



This species and L. peniculiger, described on page 298, are quite 

 similar in general appearance. Known only from the male sex, 

 the diminutive individuals are of a solidly dark brown coloration-, 



^^^ This is due to the fact that in the present genus the few heavier spines are 

 stout and the ventral femoral margins are not suppHed with hairs which increase 

 n size to become slender spines distad, as is true for C. lepta here described.
