200 LAMELLICOllNIA. 



32. Lachnosterna ? 



Hab. Guatemala, Chacoj in Vera Paz (Champion). 



Also a single female example of an apparently distinct species allied to L. setifera. 



33. Lachnosterna ? 



Hab. Mexico (coll. Bates). 



A single example ( $ ) received from Paris many years ago under the name of 

 L. lanuginosa, Dej. (Cat.). It is very distinct in being clothed with very long shaggy 

 pile, but apparently belongs to the L. setifera group ; without a knowledge of the 

 other sex it would be useless to name and describe it. 



34. Lachnosterna setidorsis. 



Anguste oblonga, subovata, fulvo-castanea vel obscure fusca, pube breyi subincumbente et pilis elongatis 

 erectis sat dense vestita, apud elytra pilis elongatis supra totum discum sublineatim seriatis ; tborace, 

 scutello, elytris et pygidio subtiliter et dense punctulatis ; clypeo obtuse rotundato, sparsim baud profunda 

 punctato, margine integro valde elevato, fronte grosse confluenter punctata et erecte longe setosa. 



S . Pygidium valde convexum, erecte . pilosum, pilis longioribus intermixtis. Venter medio longitudinaliter 

 concavus, pilifero-punctulatus, segmento 5° apice recto, medio transversim uniplicato, 6° brevi transversim 

 concavo, margine anteriore incrassato et medio late interrupto. Calcaria postica libera. Ungues fere sicut 

 in L. setifera, dente mediano valido (apicali subasquali), basi obtuse dentata. 



$ . Pygidium magis elongatum et triangulare, fere planum, cseteris sicut in S • Venter sat dense pilifero- 

 punctulatus, segmento 6° eonvexo, polito. 



Long. 21 millim. 



Hab. Costa Eica ( Van Patten). Two examples only. 



A distinct species, intermediate, as regards the fineness of the sculpture, between 

 L. setifera and L. gigantea. 



35. Lachnosterna trichia. 



Sat anguste oblonga, fuseo-rufa, dense erecte flavi-pilosa, fronte, tborace elytrorumque basi longissime pilosis, 

 dense subconfluenter punctulata, parum nitida ; clypeo mediocri rotundato, margine antico paullo elevato 

 et valde sinuato, supra discrete punctato ; tborace medio mediocriter dilatato, margine crenulato et longe 

 setoso ; scutello grosse irregulariter punctato. 



S . Pygidium convexum, breviter subrecumbenti-pilosum et sat dense erecte longipilosum. Venter medio 

 depressus, subsparse punctulatus, segmento 5° medio densius punctulato, 6° medio concavo marginibus vix 

 elevatis. Calcaria postica elongata, libera. Ungues basi paullo dilatati, dente mediano (basi paullulum 

 approximate) sat valido curvato. Antennarum clava elongata, cseteris articulis conjunctis sequalis, 4°-7 m 

 intus acuminatis. 

 $ . Pygidium triangulare, fere planum, breviter pilosum absque pilis longioribus, apice lseve politum et ante 

 apicem medio depressum. Ungues fere sicut in c? , ad basin magis dilatati. 



Long. 16-17 millim. 



Hab. Guatemala, Las Mercedes (Champion). 



Three examples only, two males and one female. 



Not very closely allied to any other Central- American species, but seems to approach 

 nearest L. testaceijpennis, in which, however, the median (or lower) tooth of the claws
