6. Paroecanthus olmecus, sp. n. (Tab. XIII. figg. 16, 17, $ .) 



P. mexicano paulo major et illi simillimus, fulvo-testaceus, notis nigris plus minus irroratus. Caput et 

 pronotum castanea vel fusco-varia. Antenna? fuscae, annulis luteis remotis. Elytra frequenter nigro- 

 picta; 2 campi lateralis vena mediastina ramis 7-8, necnon venis basalibus 3-4. Ala? brevissime 

 caudata?. Tibia? anticae subcompressae, extus tympano rotundato-elliptico, intus tympano longissimo, 

 aperto, angusto, sed haud lineari, parallelo vel leviter fusiformi, instructae. Tibiae posticae supra ad spinas 

 nigro-punctatae. Abdomen fuscescens. 



Var. Caput et pronotum rufa, vertice vittis 2 vel 4 nigris ; pronoto anguste nigro-limbato.

Figures. — Pig. 16, anterior tibia, outer side. — Fig. 17, ditto, inner side. 



Eab. Mexico, Atoyac in Vera Cruz (Schumann : 2 ), Jalapa ( M. Trujillo : <S ). 



Differs from P. tibialis in having the inner tympanum of the anterior tibiae in the 

 form of an elongated depression, this being twice the length of the elliptic opening 

 of P. tibialis and distinctly membranaceous, not a narrow ridge as in P. aztecus. 

 P. foraminatus, from Cuba, appears to be nearly allied to P. olmecus, differing from it 

 in the more rounded posterior margin of the pronotum and the coriaceous elytra, with 

 polygonal reticulation and the vena mediastina more ramose. 



7. Paroecanthus tibialis, sp. n. (Tab. XIII. figg. 14, 15, $ .) 



Statura minore ; fulvo-testaceus ; elytris in dorso notis nonnullis nigris ; P. mexicano simillimus. Antenna? 

 fuscae, annulis fulvis ornatae. Ala? vix caudata?. Tibia? anticae subcompressae, in utroque latere tympano 

 elliptico instructae : externo rotundato, interno oblongo-elliptico. — rf . Elytrorum area apicalis brevis. 



$ . Long. corp. 10*6 ; elytr. 13 ; femor. post. 9*7 ; ovipos. 5*8 millim. 



c? . Long. corp. 1 25 ; elytr. 10-5 ; femor. post. 7'4 millim. 



igitees. — Fig. 14, anterior tibia, outer side. — Fig. 15, ditto, inner side. 



Eab. Panama, Bugaba 1000 feet, Volcan de Chiriqui 3500 feet (Champion). 



In this well-characterized species the inner drum of the anterior tibiae is not linear 

 as in P. mexicanus, but narrowly elliptical as in P. foraminatus. In general facies the 

 insect resembles P. mexicanus, while P. foraminatus is of the type of P. niger, with 

 shorter wings.

8. Paroecanthus podagrosus, sp. n. (Tab. XIII. figg. 7-11.) 



Gracilis, quam P. guatemalce minor, omnino fulvo-testaceus, unicolor, haud vel parum nigro-notatus ; capite, 

 pronoto pedibusque obscure runs. Caput supra convexiusculum ; oculi sat prominuli. Antennae dimidia 

 parte basali infuscatae, annulis minimis pallidis. Palporum articulus ultimus, seque latus ac longus, 

 trigonalis. Pronotum in medio punctis impressis 2 nitidis notatum ; lobis lateralibus parum altis. 

 Ala? caudata?. Pedes graciles. Tibia? anticae tertia parte apicali graciles, in medio superne valde 

 inflatae, tumorem nitidum, impressione notatum, efficientes ; tumore intus conchato, supra tympanum 

 prominulo, ilium leviter obtegente ; tympano externo elliptico, majusculo ; interno magno, longissimo, 

 parallelo, valde aperto. Femora postica gracilia. Tibiae postica? frequenter superne fuscescentia. Meta- 

 tarsus posticus supra 1 : 3 dentatus. Tibiarum calcaria breviuscula, supero-internum tertiam partem 

 metatarsi aequans. 



2 • Elytra angusta, longa ; vena mediastina 8-9-ramosa. Ovipositor femori postico valde brevior.
