HOPLOPHORA.—PLATYCOTIS. 41 
5. Hoplophora concinna, sp.n. (Tab. IV. fige. 1, 1a, 4.) 
Minima, brevis ; pronoto fortiter punctato lete ferrugineo, supra caput utrinque nigro-notato, vitta -albida 
mox ante apicem, deinde apice late fusco, extremo ipso albido excepto, humeris obtuse prominulis, linea 
dorsali et quibusdam utrinque inequalibus elevatis; tegminibus hyalinis, venis fuscis ad basin diluti- 
oribus, margine costali preecipue ad basin punctato, maculis nigris distinctis; pedibus testaceis, posticis 
brevissimis. 
A very small, short species, with the pronotum of a bright ferruginous colour, with two large fuscous markings 
on the metopidium extending from the front margin to just behind the humeral prominences, which are 
short and blunt; on the dorsal surface there is a whitish band before the apex, followed by a dark one 
covering the whole of the apex, except the extreme tip, which is whitish; the punctuation is rather strong, 
and there is a strongly raised dorsal line and two or three more or less irregular raised lines on each side 
of this ; tegmina with the veins fuscous, lighter towards the base, with large distinct dark markings across 
the middle and on the costa between these and the base, the costal margin punctured, especially towards 
the base ; legs and underside testaceous, posterior legs very short. — 
Long. 34, cum tegm. 5 millim.; lat. 3 millim. 
Hab. Panama, Volcan de Chiriqui 2000 feet (Champion). 
One male specimen. This is a very distinct little species; the hind legs in the 
whole family are shorter than the others, but in this and in H. désparipes this charac- 
teristic appears to be especially marked. 
The subgenus Enchotype, Stal, does not appear to be represented in our collection; 
it resembles Hoplophora in having a comparatively narrow head and three apical cells 
to the wings, but in several other points it appears rather to resemble Potnia, Stal. 
PLATYCOTIS. 
Platycotis, Stal, Kongl. Sv. Vet.-Ak. Handl. Band viii. 1, p. 36 (1869). 
This genus is here considered as including the subgenera Lophopelta, Stal, and 
Microschema, Stal; they all three differ from Hoplophora in the much broader head 
and in the fact that the pronotum is not subparallel behind the shoulders, and shield- 
shaped, but is narrowed from the base; the differences inter se, however, are mostly 
comparative, and as far as the dorsal horn is concerned in certain species of Lophopelta, 
as well as of Platycotis, it is in part or entirely wanting. It may be well, perhaps, to 
add Stal’s description of the subgenera (/. c. supra, p. 37, nota) :— 
a. Thorace antice maxime declivi, margine antico inter oculos late 
sinuato. 
6. Thorace anterius convexo vel inermi vel medio ante angulos 
laterales cornu compresso, plus minus porrecto, armato. . Subg. Platycotis, Stal. 
bb. Thorace anterius convexo, dorso pone angulos laterales, cornu 
vel processu instructo. . . . . ... =.=. +. . . Subg. Lophopelta, Stal. 
aa. Thorace anterius minus convexo, sensim et haud perpendicu- 
lariter declivi, margine antico inter oculos recto, angulis 
lateralibus haud vel vix prominulis, processu postico a basi 
primum levissime, dein sensim distincte angustato . . . . Subg. Microschema, Stal.
