This very pretty Tingitid resembles AtJieas nigricomis 

 Champion but differs in having a narrower form, somewhat 

 shorter antennae, the lateral margins sinuated towards apex and 

 the nervures marked more with blackish. At the present time 

 this species is not known from any other localities, and the 

 nymphs and its foodplant are also unknown. 



Atheas exiguus n. sp. 



Body very narrow, depressed. Head a little 



broader than long, with two median black stripes and 



a small tubercle in front; antenniferous tubercles short, 



pointed at tip. Antennae slender, about as long as from 



the apex of the head to the tip of the triangular post- 

 erior portion of the pronotum, the basal two joints and 



the fourth thickened and black, the latter hardly twice 



as long as the second which is shorter than the first; 



third joint long and thin, pale yellowish with a short 



black band at base. Pronotum feebly convex, closely 



punctured, laterally narrowing towards the front, an- ATHEAS EXIGUUS 



terior margin slightly broader than the head, with a 



yellowish rim, lateral membranous margins almost 



straight, hyaline, yellowish-white, very narrow posteriorly, widening more 



anteriorly, uniseriate, with a few smaller cells within; the three pronotal 

 carinae feebly raised, yellowish, the outer ones slightly curved, shorter than 



the median carina; the apical part of the triangular posterior portion yel- 

 lowish with small round cells, tip obtusely rounded. 



Elytra elongate, widest before the middle, barely sinuated towards 

 apex and rounded at tip, the lateral margins hyaline, yellowish- white; dis- 

 coidal area narrow, widest at the middle, rather long, extending posteriorly 

 over the middle of the elytra, obtusely pointed at apex, with three or four 

 rows of very small areoles at widest part, yellowish; the inner and outer 

 longitudinal nervures brownish or fuscous; subcostal area very narrow 

 throughout with two rows of minute areoles; costal area hardly broader 

 than subcostal with one row of larger areoles and a few smaller cells near to 

 the edge. The sutural area has irregular medium sized areoles and a large 

 space at inner part closely reticulated and yellowish, the nervures more or 

 less brownish or fuscous. Rostral laminae parallel at the mesosternum. 

 Legs somewhat tawny, last tarsal joint and claws blackish. The female is a 

 little larger than the male and a trifle broader. 



Length 2. m.m. to 2.2 m.m.: width across the widest part of the elytra 

 0.6 m.m.
