STAG MATOPTERA. 187 



Pedes antici mediocriter crassi sicut in S. annulate/, ; coxis sat fortiter denticulatis ; femorum macula 

 interna obsoleta, rufescente, diffusa, margine infero nigro. 

 Long. 96 ; pronot. 38, elytr. 51, latit. elytr. 23, camp. marg. 8-3 millim. 



Hab. Panama, Bugaba 800 to 1000 feet {Champion). 

 [Var. minor, n. 



$ . Elytrorum margo costalis apice minus arcuatus, fere ut in 8. annulata, qua de causa apex elytri minus 

 obtusus. Macula discoidalis sensim minor, de reliquo illae typi conformis. Area analis hyalina, flavo- 

 fasciculata. Alae minus dense flavo-tessellatae. Femorum anteriorum spina? ad maculam internam 

 minus nigrse. Pronotum minus distincte carinatum. 



Long. 79 ; pronot. 28*5, elytr. 42, latit. elytr. 17*6, camp. marg. 6*5 millim. 



Hab. Colombia ; Venezuela (Mus. Genavense).] 



This is the only known species having the prothorax twice as long as the anterior 

 coxae, S. prcedicatoria, Sauss., excepted. It differs from the latter in having the 

 pronotum finely denticulated, quite finely at its base ; the macula of the elytra 

 somewhat different, having a thick triangular white stigma without the white arch ; 

 and the macula of the femora almost obsolete. 8. septentrionalis may be easily 

 distinguished from S. annulata, Stoll, by its- longer prothorax, its very much larger 

 elytral macula, and its anterior femora without distinct marking. The head is some- 

 what narrower than in the other species of the genus, forming in the $ a regular 

 triangle, its three sides being of equal length, as in S. prwdicatoria, while in most of 

 the other species the head is distinctly wider than high. 



[2. Stagmatoptera pia, sp. n. 



5 . Prasina, 8. annulatce simillima. Pronotum postice carinatum, marginibus tenuiter, parce denticulatis. 

 Elytrorum margo costalis apice magis oblique truncatus, subsinuatus ; macula discoidalis sat magna, quam 

 in specie laudata duplo major, sed quam in S. septentrionali minor, rotundata, fusco-rufa, anterius macula 

 callosa alba piriformi, posterius per fasciam angustam obsoletam rufam cum margine suturali conjuncta 

 (fere sicut in S. bioculata) ; margo suturalis parce hyalino-punctatus ; area analis prasina, parum hyalino- 

 punctata. Femora anteriora macula consueta nigra vel virescente. 



Long. 81 ; pronot. 32, elytr. 43, latit. elytr. 18*5, camp. marg. 7-25 millim. 



Hab. Beazil (Mus. Genavense).] 



[3. Stagmatoptera annulata, Stoll, Sauss. 



Mantis annulata, Stoll, Spectr. et Mantes, t. 25. fig. 95 ($), t. 18. fig. 66 (d). 



Var. S • Elytrorum campus discoidalis et analis vitreus, fascia prasina ad venam principalem ab oeello ad 

 apicem prseditus, inter ocellum et basin nulla. 



Hab. Beazil, Pernambuco, Bahia (Mus. Genavense). 



These males are perhaps a mere hyaline variety of S. annulata^ or they may belong 

 to some other species not yet characterized.] 



[4. Stagmatoptera femoralis, sp. n. 



? Mantis prcecaria, Miiller, Natursyst. Linn., Ins. i. p. 413, t. 9. fig. 3 ( ? ) (1774). 

 $ . Valida, prasina, S. annulatce, St., afnnissima. Pronotum paulo crassius, vix magis denticulatum.
