 longa, frequenter maculis nigris remotis rarioribus conspersa, vena mediastina distincta, divergens. 

 Pemora omnia subtus ad spinas nigro-maculata ; anteriora subtus plus minus nigrescentia, subtus 

 spinis 3 in margine anteriore notata ; posteriora biseriatim spinosa, spinis omnibus luteis. Ovipositor 

 rectus, femore sublongior.

Figube : — Pig. 22, the head and pronotum, magnified. 



Hab. Costa Rica, Tucurrique (Tristan). 



Near C. infuscatus, Scudd., but larger, with the process of the vertex shorter and 

 blunter, the lateral lobes of the pronotum higher and more angular, and the femora 

 not distinctly black beneath, but maculated and more spined than in C. infuscatus. It 

 has only one or two spines on the anterior femora. This last-mentioned character also 

 distinguishes the present species from C. fuscomarginatus and C. maculosus, Redt. 



7. Conocephalus aztecus, sp. n. 



Viridis. Vertieis rostrum quam latum vix longius, oculis longior, parallelum, apice obtusum, rotundatum,

 nitida, obsolete punctata. Os rufum, antennae rufescentes. Pronotum rugulato-punctatum ; lobi laterales 

 infra rotundato-angulati, postice rotundati. Elytra femora postica valde superantia, hie illic frequenter 

 punctis nigris minutis notata. Pemora anteriora subtus spinis 2, postica subtus utrinque spinis 8-9 ; 

 omnibus apice nigris ac ad basin macula nigra. Tibia? anticae et intermedia? subtus utrinque maculis 

 nigris ad spinas positis, atque utrinque ad basin supra macula nigra (saltern in tibiis intermediis)
