168 Mr. 11. W. Bates's additions to the 



Zenochloris harhicauda , n. sp. (PL VII., fig. 4). 

 Elongatca, sublinearis, obscure viridi-opaca, siibtus cum pedibus 

 viridi-metallica abdomineque rufo ; supra glabra, elytris apicc 

 excepta setosis. Caput rugoso-punctatum. Thorax relative 

 angustus, paullo post-medium subangulatim leviter dilatatus, 

 delude usque ad basin paullo siuuato-angustatus, supra dense sed 

 fere passim discrete punctulatus, vittiila dorsali-posteriori laevi. 

 Elytra apice breviter oblique truncata, margine laterali medio 

 jonge sinuato, epipleuris angustis prope basin latioribus, acute 

 marginatis ; dense, postice subconfluenter, punctulata, glabra, 

 opaca, aenea, apice grosse setifero-punctata. Metasternum liaud 

 dense piloso-punctatum. Abdomen punctulatum. Pedes aspere 

 punctati et breviter setosi, fenaoribus posticis valde elongatis tibiis 

 subflexuosis. Antennas breves, corporis dimidio ( 2 ) subaequales, 

 ((J) paullo longiores, nee spinosae nee ciliatte, articulo 3io scapo 

 parum longiori, 5 — 10 subcompressis, ad apicem extus breviter pro- 

 ductis. Long. IO5 — 14 miJlim. 



Hub. Mexico, Mescala in Guerrero {H. II. Smith), 

 Acapulco (/iof/c)- Three examples. 



In the form and proportions of the antennal joints, 

 and other characters, this species agrees with Z. para- 

 doxa, and I refer it to the same genus, notwithstanding 

 the difference in the facies. Two Colombian species 

 (undescribed ?) have the same sharply defined and cari- 

 nated epipleurpe, but they have a distinct thoracic lateral 

 tubercle or spine. 



Stcnosphenus suhlcevicollis, n. sp. 



S. cribrij^enni (Thoms.) affinissimus, forsan ejus varietas ; paullo 

 minus angustatus ; thorace punctis multo minoribus et paucioribus, 

 fere laevi, elytris densius magis ffiqualiter punctulatis apiceque 

 spina exteriori minus elongata. Niger, pedibus rufo-testaceis. 

 Long. 11^— 13i millim. 



Ilah. Mexico, Acapulco, Rincon, and Venta de Pele- 

 grino, in Guerrero {H. H. Sinith). 



Mr. Smith found *S'. crihripennis also in Guerrero, 

 chiefly at Chilpancingo ; and Herr Hoge took it in con- 

 siderable numbers at various localities in the same State, 

 including Acapulco.
