376 PHYTOPHAGA. 



of the tibia All this agrees perfectly with the description given by the author, but 

 without comparison with the type all doubt as to the identity of certain species is not 

 excluded. 



9. Longitarsus buckleyi. 



Longitarsus buckleyi, Baly, Trans. Ent. Soc. 1877, iv. p. 291 \ 



Hab. Guatemala, San Geroniino {Champion).— Ecuadok 1 . 



The four specimens from Guatemala before me, although of smaller size than the 

 type which I have for comparison, do not seem to differ sufficiently to be considered 

 specifically distinct. The species is of a uniform shining black colour, and with the 

 anterior legs and the posterior tibiae obscure fulvous ; the description of Mr. Baly gives 

 the thorax as finely rugose when seen under a strong lens (in my opinion this is 

 erroneous, as I can only discover exceedingly minute punctures, so that the thorax may 

 almost be called impunctate) ; the elytra have also very minute rows of punctures, but 

 more distinct than those of the thorax ; the second and third joints of the antennae are 

 of nearly equal length. 



10. Longitarsus concinnus. 



Longitarsus concinnus, Baly, Trans. Ent. Soc. Lond. 1877, p. 290 \ 

 Hab. Mexico 1 (Pilate). 



The type, contained in Mr. Baly's collection, bears a label on which the locality 

 " Mexico " is marked with a % and it is therefore possible that the species was not 

 originally obtained from that country. L. concinnus may be known from the many 

 similarly-coloured species by the distinct punctuation of the thorax and elytra, and by 

 the black colour of the sixth to the ninth joints of the antennae. I have only seen a 

 single specimen of this insect. 



11. Longitarsus apicicornis. 



Black ; the three basal and the two apical joints of the antennae fulvous ; thorax impunctate ; elytra extremely 

 finely punctured. 



Length 1 line. 



Head with a short impressed line near the inner margin of the eyes ; frontal tubercles broad, flattened, and 

 scarcely raised ; carina very narrow and short; antennas as long as the body, the second and third joints 

 of nearly equal length, the first joint elongate, curved, thickened at the apex, and black above, the three 

 following as well as the two terminal joints fulvous, the intermediate ones black ; thorax subquadrate, 

 only about one half broader than long, its surface entirely impunctate ; elytra subcylindrical, convex, 

 without basal impression, the very minute punctuation (only visible under a very strong lens) arranged in 

 lines ; legs entirely black ; first joint of the posterior tarsi less than half the length of the tibia. 



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



Two specimens were obtained. The colour of the antennae and the entirely black 

 upper and under surface distinguish this species.
