AMBLYDISCA.—-CATORTHORRHINUS. 213 
strongly punctured at the base, and smooth and shining at the apex, with the part between dotted 
with small rugosities, which, for the most part, proceed as short irregular lines from the strongly raised 
veins ; abdomen pitchy; legs variegated with reddish and yellowish-testaceous, the tarsi, knees, and 
femora pitchy. 
Long. ad apicem abdominis 24, ad apicem tegminum 19 millim.; lat. ad hum. 5 millim. 
Hab. Costa Rica (Sallé). 
I feel considerable hesitation in retaining this and the preceding species under 
Amblydisca, but it is best, in the present state of our knowledge, not to multiply the 
genera of the group without very good reason; if we are to go by the shape of the 
clypeus they fall under Amblydisca, if by the formation of the vertex they may well be 
separated from it. A transition, however, is afforded by A. multiguttata. 
ACROBELUS. 
Acrobelus, Stal, Kong]. Svensk. Vet.-Ak. Handl. Band viii. 1 (Hemipt. Fabr. ii.), p. 60, nota (1869). 
This genus was formed by Stal to receive Tettigonia reflera, Sign., which appears to 
be synonymous with Rhaphirhinus attenuatus, Walk.; it may be distinguished from 
Raphirhinus, Lap. (Rhaphidorhinus, Stal), by the head being gradually prolonged into a 
stout recurved process, which is excavate above and below, whereas in the last-named 
genus (which is represented by &. phosphoreus and Tettigonia rugosa) the process is 
slender and not excavate above, and proceeds abruptly from the head, the apex of 
which is much broader than the process. |

CATORTHORRHINUS, gen. nov. 
Axylacizi similis, sed vertice declivi in processum brevem erectum producto, hoc supra subtusque profunde 
excavato; metopidio a latere viso ut in Amblydisca angulato; oculis fortiter prominentibus; pronoto 
antice vix angustato, subparallelo, rugose punctato, ante scutellum leviter sinuato; tegminibus parallelis. 
Allied to Aulacizes, which it closely resembles, except that the vertex of the head slopes upwards from the 
eyes and is continued into a short upright process, which is excavate above and below, the excavation 
being continued on the metopidium ; the metopidium, viewed from the side, forms a small angle, as in 
Amblydisca ; the pronotum is scarcely narrower in front than behind, rugosely punctured, and only 
slightly sinuate before the scutellum ; tegmina parallel; anterior tibiee not excavate. 
1. Catorthorrhinus resimus, sp. n. (Tab. XIII. figg. 10, 10 a.) 
Testaceus, capite pronotoque unicoloribus ; scutello testaceo, levissime sculpturato ; tegminibus flavo-testaceis 
plus minusve distincte fulvo-notatis, apice griseo, subhyalino ; corpore subtus antice testaceo, abdomine 
subtus albido ; pedibus testaceis vel fusco-testaceis. 
Of a testaceous colour, with the abdomen underneath whitish, and the tegmina yellowish-testaceous, with more
