5. Oliarus humeralis, sp.n. (Tab. X. figg. 18, 18 a.) 
Precedenti affinis, sed capite minori, vertice latitudine Jongiori et fronte ad basim magis contracta; pronoto 
brevissimo ; scutello minus distincte quinque-carinato; tegminibus lacteis ad humeros fuscatis, venis 
albidis, ad apicem sparsim fusco adspersis ; pedibus dilute testaceis. 
Allied to the preceding, but with a smaller head and narrower vertex (in these points the species resembles 
O. concinnulus) ; the forehead evidently more contracted before it joins the vertex; scutellum rather 
indistinctly carinate; tegmina milky, semitransparent, with the basal fourth part fuscous; the suture in 
the middle is very narrowly infuscate, and there are a few small fuscous spots at the apex; the veins 
are white or whitish, darkened at the extreme apex; legs light testaceous.

intermediis indistinctis ; tegminibus sublacteis, venis distinctis fuscis, granulosis; abdomine nigrescenti, 
pedibus plerumque testaceis. 
A somewhat large species, with a short and broad head, the vertex being quadrate, and the eyes, viewed from 
above, plainly broader than long; frontal ocellus very distinct ; scutellum with three distinct carine, and 
two feeble carine on each side of the central one, which are abbreviated in front; tegmina subpellucid, 
slightly milky, with plainly-marked granulose veins, and with several small fuscous spots on the dise, 
some of the veins, too, towards the apex being bounded with fuscous; abdomen black; legs testaceous, 
femora infuscate.

7. Oliarus chiriquensis, sp.n. (Tab. X. figg. 20, 20 a.) 
Varians, capite parvo, vertice latitudine longiori, ante oculos vix producto ; pronoto brevissimo, viridescente ; 
scutello distincte quinque-carinato ; tegminibus subparallelis, lateribus rotundatis, pellucidis, nitidis, 
interdum ad basim nigris, venis distinctis, fusco-notatis ; pedibus testaceis. 
Head small, much narrower than the pronotum, with the vertex longer than broad, and very slightly produced 
in front of the eyes; frons broadest just before the clypeus, brown, mottled with greenish ; frontal ocellus 
not distinct, but present; pronotum very short, greenish; scutellum testaceous, with greenish margins, 
with a distinct dark central carina and two others on each side of this; tegmina shining, vitreous, with 
the base sometimes strongly but irregularly darkened between the shoulders and the scutellar regions, the 
veins strongly marked, partly light-coloured, but distinctly marked with fuscous, the forks of the radial 
and second ulnar veins being thus made especially conspicuous; the costal margin also variegated ; legs 
testaceous.

A fair series, but all females. The greenish colour of the frons, pronotum, &c., is 
probably much more conspicuous in life; in some specimens it has entirely faded. 
The frontal ocellus, viewed under an ordinary lens, is very hard to trace, and in some
