102 HEMIPTERA-HOMOPTERA. 
parent, with fine testaceous or fuscous venation, and with a dark patch on the external margins before the 
apex; abdomen pitchy, more or less marked with red above; legs light testaceous. 
Long. cum tegm. 34 millim.; lat. ad hum. 13-14 millim. 
Hab. Panama, Bugaba (Champion). 
A handsome little species, and probably very brightly coloured in life, the contrast 
between the red head and pronotum and the black scutellum being especially noticeable. 
Two females in our collection, from Cerro Zunil, Guatemala, are perhaps a variety 
of E. pulchella; they have the front parts darker, the pronotum a little shorter, the 
scutellum more or less shining, and the sides of the clypeus less evidently keeled. 
MNEMOSYNE. 
Mnemosyne, Stal, Hemipt. Afr. iv. p. 150 (1866) ; Kong]. Svensk. Vet.-Ak. Handl. viii. no. 1, p. 91. 
Stal places this genus among the Dictyopharida. The species I have identified as 
M. planiceps is superficially like a large Civius or Oliarus. It may be characterized 
thus :— , 
Vertex very narrow; the three keels on the scutellum more or less obsolete, the side ones being sometimes 
very faint ; the frons broad before the apex, and like the clypeus keeled in the middle and at the sides ; 
no frontal ocellus is present, but the round scar is sometimes very distinct ; tegmina more or less pellucid, 
the clavus with the posterior vein situated at some distance from the suture, and not continued to the 
apex, forming a fork with the transverse vein at about the middle, the radial vein of the corium forked 
much before the interior ulnar vein ; posterior tibiw bispinose. 
Thé male-characters are somewhat complicated, and differ from those of Civius and its immediate allies.

Mnemosyne cutana, Stal, Berl. ent. Zeitschr. 1866, p. 391°. 
Hab. Panama, Volcan de Chiriqui and Bugaba (Champion). —Sovuta America! ?; 
British Guiana, Bartica (coll. Bail); Cusa?. 
Mr. Ball has sent me two female specimens of this species from British Guiana, and 
they are structurally identical with our Panama insect, though differing slightly in 
colour and in having the minute granulations on the apical and subapical areas of 
the tegmina more numerous. I have not seen Stal’s types, but his brief diagnoses 
of M. planiceps and M. cutana agree with our examples, of which a full description 
is appended :— 
Sordide testacea, vertice perangusto, subexcavato, ante oculos magnos paullo producto, oculis infra levissime 
emarginatis; rostro tenui, prelongo; tegulis magnis, dilutioribus; scutello haud nitido, levissime sed 
distincte sculpturato ; tegminibus longis, subpellucidis, fusco sparsim, precipue ad medium et apicem, 
notatis, areis apicalibus et subapicalibus granulis minutis instructis, postice leviter dilatatis; abdomine 
nigrescenti ; pedibus testaceis.
