ORTHOPLOPHORA.—ACONOPHOROIDES. AT 
‘The insect on which I have formed this genus bears a close resemblance at first sight 
to the figure of Umbonia indicator, Fairm. [Ann. Soc. Ent. Fr. sér. 2, iv. p. 279, t. 6. 
fig. 14 (in error for 15)], but the apex of the pronotum in the figure extends to the 
apex of the tegmina, and for this reason Fairmaire, certainly with considerable doubt, 
places it in Umbonia ; the shoulders, moreover, in Fairmaire’s insect are scarcely at all 
produced. | 
The genus above described is distinguished from Potnia by the quite horizontal, or, 
if anything, slightly deflexed horn, and the fact that the wings have four apical cells, 
and from Enchotype by its broader head (in which it resembles Platycotis), and, as in 
Potnia, by the formation of the horn; the general facies, moreover, is quite different 
from that of either genus. 
1. Orthoplophora salvini, sp.n. (Tab. IV. figg. 10, 10 a.) 
‘Grisea, pronoto fortiter punctato, lined dorsali vix elevata, cetera fere plano, nec lineis lateralibus instructo ; 
capite lato, nigro ochraceo-maculato; metopidio duabus transversis maculis supra caput et supra has 
duobus punctis nigris; cornu unicolori, apice indistincte rubro excepto, utrinque ad basin vitta lata 
nigra usque ad maculam nigram parvam lateralem utrinque ad marginem pronoti paullo ante apicem 
positam ; pronoti marginibus anguste rufis et vitta indistincté ruf& supra humeros in metopidium con- 
tinuatd ; tegminibus hyalinis, ad basin ochraceis, fortiter punctatis, areis subcostalibus flavo-rufescentibus, 
venis nigris; alis ad apicem infuscatis ; pedibus testaceis, tarsis plus minusve fuscis. 
‘Of a greyish colour, slightly ochraceous in front and at the sides, strongly punctured, with a feebly raised dorsal 
line and no elevated lines on each side; the head is black, closely marked with small yellowish, slightly 
raised patches, and there are dark markings on the metopidium ; the horn of the pronotum is unicolorous, 
slightly reddish at the apex, and from its base start two broad black bands, which reach for about two-thirds 
of the distance between the humeral prominences (which are black externally and reddish beneath) and 
the apex of the pronotum; the margins are reddish and the reddish colour is continued in two bands on 
each side between the shoulders and the black bands before mentioned ; these reddish bands almost meet 
just above the head; the tegmina are hyaline, with black veins, ochraceous at the base, and with the 
subcostal areas yellowish-red; the wings are infuscate at the apex, and the legs are testaceous, with the 
tarsi fuscous, the hinder pair, as before mentioned, being more slender and having longer tarsi than is 
usual in the Hoplophorine. 
Long. 9, cum tegm. 13 millim.; lat. inter cornua 43 millim. 
Hab. Mexico, Rinconada in Vera Cruz (Schaus). 
One male specimen. 
ACONOPHOROIDES, gen. nov. 
‘Quoad formam -Aconophore affinis, sed tarsis posterioribus minutissimis, lateribus pronoti carinatis et lateribus 
cornus fortiter porrecti multo-carinatis facile distinguendus. | 
This genus is formed to receive A, gladiator, Walk. (=Thelia gladiator, Walk.), and 
one or two allied species, which have been classed under Aconophora, but are much more 
closely related. to Potnia and Hoplophora: in fact, the genus must be removed to the 
Hoplophorine. In form the genus resembles large broad specimens of Aconophora, but 
may be easily distinguished by the very small posterior tarsi (the intermediate and
