erectis prope basin et suturam ; pectore fulvo-villoso. 

 <J . Pygidium convexum, sat dense piloso-punctatum. Venter medio depressus et vage canaliculars, segmentis 



medio erecte pilosis, 6° medio lato, fere piano, canaliculate. Calcaria postica elongata, libera. Ungues 



apice prolongate recti, dente basali magno, inferiore robusto, subrecto ; intermedii difformes, ungue exte- 



riore validiore, torto, abrupte inflecto et extus appendiculato. Antennarum clava valde elongata, cseteris 



articulis conjunctis longior.

acutiore et curvato, basali sicut in $ ; intermedii normales. 

 Long. 14-15 millim. 



Hab. Mexico, Ciudad in Durango (Forrer, Hoge), Toluca (Edge). 



The displaced median tooth of the male middle claws is in this species greatly elon- 

 gated, and looks like a third claw. 



A male example from Ciudad is figured. 



18. Lachnosterna macrophylla. (Tab. XI. fig. 3, <? .) 



L. anornaloidi proxime affinis. Breviter oblongo-ovata, castaneo-fusca, elytris breviter in cumbenti- griseo- 

 pilosis, fronte, thorace elytrorumque basi longissime hirsutis ; clypeo transversim quadrato, profunde 

 concavo (marginibus integris alte reflexis), sparsim punctato ; tborace postice baud angustato, angulis 

 posticis acutis, nitido, forte punctato : elytris punctulatis ; pectore fulvo-villoso. 



cJ . Pygidium convexum, longe erecte nirsutum. Venter medio depressus vel concavus, sparsim setosus, segmento 

 5° apice medio et 6° (medio canaliculato) paullo densius asperato-punctatis et setosis. Calcaria postica 

 elongata, libera. Ungues tridentati, apice (dente apicali) multo longiore et acutiore, dente inferiore latiore 

 et breviore, basali magno triangulari ; intermedii difformes, sinistro abrupte curvato et apice prolongate 

 Antennarum clava pallide fusca, longissima, caeteris articulis longior, articulis 5°-7 m brevibus, intus acute 

 productis. 



Long. 12-14 millim. 



Hah. Mexico, near the city (Flohr). Many examples, all males. 



Agrees closely in most of its characters with L. miomaloides, and, in the clothing of 

 the ventral surface, especially with the variety of that species ; but the general form is 

 totally different, being much shorter and relatively broader — this, together with the 

 long hairs of the anterior part of the body, being constant in numerous examples, there 

 can be little doubt that the species is distinct. 



19. Laclinosterna dasypoda. (Tab. XL fig. 4, c? .) 



Sat anguste elongato-oblonga, nitida, tenuiter eubsparsim erecte longipilosa et disperse grossius punctata ; 

 castaneo-rufa, elytris fulvo-testaceis, capite nigro ; capite grossissime confluenter punctato, oculis maximis, 

 clypeo semicirculari, margine antico reflexo, integro (in <$ interdum) leviter sinuato ; tborace minus 

 transverso, mediocriter medio rotundato-dilatato margineque crenulato, sat abundanter sed distanter 

 subgrosse punctato ; pectore fulvo-villoso. Pedes elongati, validi longipilosi, tarsis subtus densius et 

 brevius pilosi. 



3 . Pygidium valde convexum, politum, longissime erecte fulvo-pilosum, punctis minutis. Venter medio con- 

 cavus et canaliculatus, sat dense setosus, suturislate deletis, segmento 6° laevi, medio transversim concavo, 

 margine anteriore incrassato medio late interrupto. Calcaria postica elongata, libera. Ungues dimidio 

 basali intus dilatato denteque mediano (a dilatatione baud separato) parvo acuto ; intermedii difformes, 

 magis curvati exterioreque basi valde irregulariter dilatato, interiore normali. Antennarum clava valde
