HEBETICOIDES. 53° 
‘On examining two’ specimens which I had without doubt assigned to Hebetica, I 
found that they had three veins starting from the base of the corium as in Leptosticta. 
I afterwards found a third specimen among some undescribed Membracide from the 
Stockholm Museum which presented much the same characteristics of venation; as 
Stal forms his genera chiefly on this character, the only alternative appears to be either 
to include them under Leptosticta or place them in a new genus. If facies is to be 
regarded at all they cannot be separated far from Hebetica, and cannot well be associated 
with Leptosticta; I have therefore adopted the latter alternative, though with some 
reserve, for although the veining of the corium as regards the two or three veins, as 
the case may be, which start from the base seems constant, yet it must be admitted 
that there is considerable variation in other points: the discoidal areas, for’ instance, 
are sometimes of different relative sizes, and through the absence of _a transverse vein 
one only may te present where there ought normally to be two; the tegmina of the 
same insect, moreover, are often different in slight points. At the same time, in the 
absence of more definite characters, the venation is very valuable as a means of distinc- 
tion; and St&l’s genera cannot be set aside, at all events in the present state of our 
knowledge and without the examination of much more material than we at present 
possess. It may be well perhaps here to quote the characters } assigned by Stal to 
Hebetica and Leptosticta respectively as regards venation :— 
“ Corio venis longitudinalibus duabus, ven4 ulnari paullo ante medium, vend radiali in medio vel pone medium 
corii furcatis, area discoidali exteriori minutissim4, interiore magna elongata; capite thoraceque puberulis ; 
tegminibus ultra latera thoracis nonnihil prominnlis. Subg. Hebetica, Stal (types Darnis convoluta, Ol.,: 
D, limacodes, Burm.).” 
Corio venis longitudinalibus tribus, radiali et duabus ulnaribus, e basi emissis, ulnaribus basin versus contiguis, 
areis discoidalibus duabus, interiore nonnihil ante medium corii extensa, basi venula transversa, inter venas 
ulnares ducta, terminata, exteriore in furcé vene radialis, pone medium corii sité, area interiore breviore. 
Subg. Leptosticta, Stal (type D. flaviceps, Burm.).” 
Leptosticta flaviceps bears a superficial resemblance to Darnis lateralis. In the 
Vienna Museum there is an insect of Signoret’s labelled “limbata” from Mexico. 
Darnis limbata is quoted by Butler (Cist. Ent. ii. p. 341) as a synonym of L. flaviceps ; 
but it is evident, on examination of the tegmina, that the insect here referred to is 
Stictopelta affinis. 
1. Hebeticoides acutus, sp. n. (Tab. IV. figg. 17, 17 a—-d, 3 .) 
Latior, nigro-purpureus ; capite metopidioque supra frontem flavis, limboque laterali pronoti virescenti-flavo 
plus minusve indistincto; ocellis approximatis; pronoto humeris a fronte viso deorsum prominulis, 
distinctius punctato, ad apicem valde angustato, apice ipso acutissimo; tegminibus fusco-purpureis, intus 
dilutioribus ; pedibus flavo-testaceis; abdomine plerumque nigro, marginibus segmentorum flavis. 
A rather large species, broad in front and narrowed to a very sharp point behind, of a purplish-black colour, 
with the head and the part just above it yellow, and the pronotum with a broad greenish-yellow margin, 
extending from behind the shoulders to some little distance before the apex; punctuation, except of the 
head and metopidium, distinct and comparatively strong; tegmina of a purplish-fuscous colour, browner
