136 HEMIPTERA-HOMOPTERA. 
Hab. Panama, David in Chiriqui (Champion). 
Four specimens, two of which are much darker than the others, but this is evidently 
due to discoloration. The sculpture is somewhat variable. In general appearance 
this species very closely resembles Amastris obtegens, F., which appears to be identical 
with, or very closely allied to, Thelia tacta, Walk., but is easily separated by the 
entirely different venation of the tegmina. The genus Thelia, according to Walker, is 
made up of the most discordant elements, and includes species belonging to Antianthe 
(Ianthe), Stictocephala, Carynota, Amastris, Telamona, Aconophoroides, and other 
genera, the mixture of which has caused very great confusion, which has been worse 
confounded by Stal neglecting purposely or accidentally to verify Walker's work in 
certain cases. 
7. Adippe inzqualis, sp.n. (Tab. VIII. figg. 20, 20 a.) 
Brunnea vel rufo-brunnea, haud nitida, pronoto inequali plus minusve late nigro- vel nigro-brunneo-notato, sat 
fortiter subrugose punctato, carina centrali acutd a latere visé rotundata leviter sinuata, et carina altera 
acuta abbreviata inter hance et humeros prominulos instructaé ; tegminibus hyalinis, margine exteriori late 
brunnea, punctata, ante apicem fuse; corpore subtus brunneo; pedibus testaceis, ad partem infuscatis. 
A small species of a lighter or darker brown, rufous-brown, or brick-red colour, variegated with darker colour ; 
dull, with the pronotum, if viewed from the side, evenly rounded and only very slightly sinuate, but if 
viewed from above uneven, with a strong central carina and two almost equally strong abbreviated 
carinze on each side of it, and traces of other coste beneath these ; the punctuation is close and distinct ; 
tegmina hyaline, with the exterior margin broadly opaque, except before the apex, with the usual fuscous 
patch near the apex; underside brown; legs testaceous, more or less infuscate. 
Long. 4-44 millim. ; lat. int. hum. 2 millim. 
Hab. Guatemata, San Juan in Vera Paz (Champion); Panama, Bugaba, Volcan de 
Chiriqui 2500 to 6000 feet, Pefia Blanca 3000 to 4000 feet (Champion). 
According to Stal’s definition of the genus, this species is intermediate between 
Oxygonia and Adippe, as it is strongly carinated on each side of the central keel. 
The general structure of the insect, however, is too near that of the preceding to 
separate it, and it must be regarded as a connecting-link between these genera. It is 
very variable in colour, the dark tint sometimes covering all the front part of the 
pronotum, and sometimes being almost absent; at the apical portion of this colour there 
is often a more or less defined lighter band, behind which the apex is broadly and uni- 
formly testaceous, the separation being very abrupt; occasionally, however, the colour 
is lighter in front and is terminated by a dark band. The single specimen from Pefia 
Blanca presents some differences, and may eventually have to be referred to a separate 
species. 
An example from Bugaba is figured. 
8. Adippe grisea, sp. n. | 
Elongata, pronoto leviter punctato, brunneo-griseo, metopidio brunneo-marmorato, et dorso obscure variegato, 
fere unicolori, carina centrali a latere visi equaliter rotundata, costisque quibusdam utrinque plus minusve
