LACHNO STERNA. 199 



The clothing of the upper surface consists of obliquely-planted grey hairs with a few 

 longer erect hairs, and in some examples extremely long hairs, especially towards the 

 base of the elytra. 



The length varies from 17 to 25 millim., but the great majority of the examples 

 measured are about 20 millim. The following are varieties : — 



Var. 1 (L. menetriesi, Blanch., Burm. ?). Brevius et latins ovata, fusco-nigra, dense et regulariter breviter 

 griseo-pilosa, pedibus abdomineque interdum nigris. 



Hab. Guatemala, Volcan de Atitlan, Pantaleon {Champion) ; Nicaragua, Chontales 

 (Janson); Costa Kica (Van Patten); Panama, Bugaba (Champion), Chiriqui (Trotseh). 



Var. 2. Minor (15 millim.) ; fuseo-nigra, brevissime sat dense subreete griseo-pilosa, clypeo margine alte elevato 

 pygidioque snbnitido, perspieue punctulato ; unguibus basi latis. 



Hab. Panama, near the city (Champion). One male only, with the characteristic form 

 of the apical ventral segments very conspicuously developed. 



Var. 3. L. trotschi. Postiee dilatata, fusco-rufa, capite thoraceque exeeptis fusco-nigris ; clypeo margine antico 

 medio depresso subsinuato, pubescentia tota fulva nee grisea. Long. 20 millim. 



Hab. Panama, Chiriqui (Bibbe). Three examples only. 

 We figure a typical male from Jalapa. 



30. Lachnosterna crinalis. 



Ovata, supra longe et dense, sed breviter, pilosa, pilis longioribus erectis intermixtis, thorace apice elytrisque 

 basi pilis nonnullis longissimis, castaneo- vel nigro-fusca, elytris subopacis ; clypeo transverso, antice 

 obtusius rotundato, supra concavo, nitido, sparsim haud profunde punctato, fronte dense rugoso-punctata ; 

 thorace subtiliter discrete punctato, linea medio-dorsali laevi, medio mediocriter dilatato margineque 

 crenulato ; elytris punctulatis, ecostatis, subpruinosis ; pectore fulvo-hirto. 



<$. Pygidium mediocriter convexum, sat dense sequaliter punctato-pilosum. Venter medio canaliculatus, 

 opacus, breviter sat dense punctulato-setosus, suturis 2 a et 3 a medio antice angulatis, segmento 5° medio 

 granulato, apice transverso, depresso et margine medio longitudinaliter canaliculato, 6° medio concavo 

 granulate. Calcaria postica elongata, libera. Ungues dente mediano sat valido paullo curvato acuto, 

 inter dentem et basin latiores. Antennarum clava articulis 2°-7 m eonjunctis haud longior. 



Long. 16-17 millim. 



Hab. Mexico, Puebla, Tlatingo (Salle). Two examples, both males. 



Approaches the L. Integra group, but differs in the clypeus being transverse and 

 obtusely rounded, not semicircular, and in the stronger median tooth of the claws, 

 this tooth not lower than the middle. The hairs of the upper surface are also longer, 

 finer, and a little more erect. 



31. Lachnosterna — ? 



Hab. Nicaragua, Chontales (Belt). 



A single example (?) of a distinct species.
