156 LAMELLICOENIA. 



c? . Tarsi gracillimi, subtus pilosi ; anticis artieulis 2°-4 m mediocriter dilatatis, subtus palmatis densissime 



pilosis ; intermediis perparum dilatatis. 

 Long. 14 millim. J • 



Hab. Mexico (Salle, ex coll. Sturm). Two male examples only. 



So closely resembling the Chilian L. palpalis (Eschsch.) that if it were not for the 

 much narrower dilatation of the male tarsal joints I should have little hesitation in 

 referring it to that species. The form, colour, pubescence, punctuation, and shape of 

 the head are exactly as in ordinary examples of L. palpalis ; but the hind tarsi are 

 longer, much thinner, and less hairy beneath; and the dilated second to the fourth and 

 the base of the first joints of the two anterior pairs are much narrower than long, the 

 fourth of the anterior and the second to the fourth of the intermediate pair further 

 differing in being only a little broader than undilated joints. 



5. Liogenys pubereus. (Tab. IX. fig. 21, 2 .) 



Sat elongato-oblongus, undique pilis brevibus discretis inclinatis fulvis ; nigro-aeneus vel (immaturus ?) 

 castaneus, aeneo-tinctus, antennis et tarsis rufo-piceis, illis clava falva ; capite lato, crebre grosse punctate ; 

 clypeo parum angustato, antice late subsinuatim truncato, angulis acutis ; tborace transverso, dense punc- 

 tato, angulis posticis apice acutis ; elytris sat dense regulariter punctatis, geminato-striatis sed costis haud 

 elevatis, seriatim punctatis ; pygidio parvo, grosse punctato ; sternis abdornineque punctatis, medio 

 lgevioribus ; tibiis anticis bidentatis. 



S . Tarsi 4 antici artieulis l°-4 m latioribns, oblongis, subtus palmatis densissime pilosis ; cseteris subtus minus 

 dense pilosis. Pedes toti pilosi. Ventris segmentum 6 m interdum latens. 



2 . Tarsi 4 antici artieulis l°-4 m subtus dense pilosis sed haud dilatatis ; cseteris subtus minus dense pilosis. 

 Pedes toti sparsim setosi nee pilosi. Yentris segmentum 6 m conspicuum sed breve. 



Long. 12-13 millim. 



Hah. Mexico, Cordova, Etla, Peras, Oaxaca (Salle), Vera Cruz (Hoge). 



Var. $ . Cuprascens ; sparsius punctatus, fere nudus (? detritus). 



Hab. Mexico, Panislahuaca(#«^). 



Numerous examples in the Salle collection are named Liogenys cribraticollis, Reiche 

 (MS.), a name which I do not adopt, as it might lead to confusion with Diplotaxis 

 cribraticollis, Blanch., L. pubereus being an aberrant Liogenys with characters showing 

 an affinity with Diplotaxis. 



A specimen from Etla is figured. 



6. Liogenys (?) ? 



Hob. Mexico, Yolos (Salle). 



A single female example without pubescence above (\ abraded), and very coarse 

 and sparse sculpture. 



7. Liogenys (?) ? 



Hab. Mexico, Cordova (Salle).
