posticae 5-6, apice nigris. Tibiae intermediae supra margine postico spinis 1 vel 2 : posticae spinis 12-9, 



apiee nigris. Abdomen concolor. 

 § . Ovipositor validus, quam pronotum fere triplo longior, rectus ; dimidia parte basali testacea, tumore basali 



et dimidia parte apicali nigris ; margine supero crenulato, apice integro. Lamina infra-genitalis trigo- 



nalis, apice minute incisa. 

 2 . Long. corp. 27; pronot. 7 ; elytr. 27*5 ; femor. post. 19; ovipos. 18*5, lat. 3-8 millim. 



Rah. Guatemala (Mus. Genavense). 



This species is closely allied to L. variabilis, Brunn., from Colombia and Brazil, 

 differing from it in having transparent borders to the transverse venula? of the wings 

 and a longer and stouter ovipositor. 



3. Lichenochrus brevistylus, sp. n. 



L. variabilis major. Fulvo-grisea, plus minus fusco-marmorata. Pronotum dense granulosum, dorso piano ; 

 canthis lateralibus explicatis, intus arcuatis per sulcos 2 valde incisis. Lobi laterales quam in L. variabili 

 altiores, inf'ere sensim coarctati, antice obtusanguli, postice rectanguli, margine infero leviter undato, 

 margine antico haud sinuato. Discus flavidus, maculis fuscis lineis 2 formantibus, in medio conjunctis, 

 abbreviatis, ornatus ; margine postico medio fusco-bimaculato. Lobi laterales ad canthos fusco-marginati, 

 in medio fuscescentes, marginibus late flavicantibus. Elytra abdominis longitudine, fulvescentia, fusco- 

 marmorata. Alee semiorbiculares, infuscatae, campo marginali fulvescente ; area mediastina basi fusca, 

 margine anguste decolore. Pedes fusco-maculosi. Femora antica et intermedia subtus spinis 4 ; postica 6, 

 et ante illas margine triundato. Spinae omnes luteae. Tibiae intermediae supra spinulal, posticae margine 

 interno spinulis 11-12. 



§ . Ovipositor margine supero recto (nympba). 



d 1 . Cerci crassi, teretes, apice incurvo, mucronato. Lamina infra-genitalis triangulariter incisa; stylis 

 teretibus brevioribus instructa (quam lati vix quadruplo longi). 



<J . Long. corp. 30 ; pronot. 7 ; elytr. 28 ; femor. post. 19 ; styli 1-5 millim. 



Hob. Mexico, Cordova {Mus. Genavense). 



This species must be placed near L. variabilis and L. vaginalis. It may readily be 

 known by the acute margin of the disc of pronotum, the lateral lobes" of which are 

 higher than in the other species of the genus ; the shorter and straighter femora ; and 

 the less elongate elytra of the male, these being six times as long as wide in 

 L. variabilis.

5. Lichenochrus nigrifrons, sp. n. 



Statura media. Ochracea, plus minus fusco-marmorata. Antennae fusco-annulatae. Frons tota fusco-nigra. 

 Pronotum sparsius, in mesozona crassius granulatum. Prozona tota fornicata, canthos haud explicatis, 

 lateraliter costata. Metazona margine postico sensim arcuato, canthis lateralibus prominulis, granosis, 

 antice valde convergentibus ac sinuatis. Pronotum supra et lateraliter ad canthos irregulariter fusco- 

 lineatum, ad marginem posticum medium maculis elongatis 2 nigris notatum. Elytra et alae concoloria, 

 in areolis fusco-maculata (in marginibus verisimiliter fusco-tessellata). Femora antica pronoto sesqui-
