2 LONGICORNIA. 
1. Parandra glabra. 
Attelabus glaber, Degeer, Mém. iv. p. 351, t. 19. £. 14-16 (1774). 
Parandra glabra, Gyll. Syn. Ins. App. i. p. 145 (9). 
Parandra mandibularis, Perty, Del. Anim. Art. p. 84, t. 17. f. 1 (1830). 
Parandra barbata, Thoms. Mus. Scientif. p. 95 (1860). 
Parandra grandis, Thoms. Mus. Scientif. p. 79 (1860). 
Hab. Nicaracua, Chontales (Belt, Janson) ; Costa Rica, Volcan de Irazu (Kogers).— 
CoLoMBIA; VENEZUELA; Ecuapor; SoutH Braziu to Rio Janeiro. 
I have compared numerous Central-American examples of this largest of the Pa- 
randre with others from Ecuador, Venezuela, and South Brazil, without: finding ‘any 
difference of specific value amongst them. Slight differences in strength of punctuation 
occur ; but in the more essential characters of the form and dentition of the mandibles, | 
and in the outline of the thorax and front edge of the clypeus, all agree closely. 
2. Parandra polita. (Tab. I. fig. 3.) 
Parandra polita, Say, Journ. Bost. Soc. N. H. i. p. 192 (1835)’. 
Parandra cylindrica, Thoms. Mus. Scientif. p. 82 (1860). 
‘Hab. Nortsa America, Indianat.—Mexico (Sallé); Guarzmata, Zapote (Champion). 
The figure is taken from a well-developed male, with very dark-coloured head, from 
Mexico. 
Dr. Horn, of Philadelphia, first pointed out the identity of Say’s species with the 
well-known cylindrica (so called, although a linear and flat insect). | 
8. Parandra scaritoides. 
Parandra scaritoides, Thoms. Mus. Scientif. p. 82. 
Hab. Nicaraaua, Chontales (Belt, 1 ¢ ).—SoutH AMERICA, Carthagena. 
Very closely allied to P. polita, differing chiefly in the more projecting and acute 
angles of the orbit of the eyes in the ¢, and by the more conspicuous punctuation 
of the surface. The insect is also relatively broader. 
4, Parandra angulicollis, 
Modice elongata, rufo-ferruginea, passim fortiter (subtus minus crebre) punctata ; antennis thoracis basin attin- 
gentibus, articulo 3° subgloboso, 4°-10™ subquadratis ; thorace quadrato, ante basin sinuatim fortiter 
angustato, angulis omnibus productis acutis; tarsi paronychio unico. 
Long. 9-103 lin. ¢ Q@. 
Parandra punctata, Bates, Trans. Ent. Soc. 1872, p. 166 (nec punctata, White). 
6 mandibule dentibus tribus apicalibus, supra longitudinaliter fortiter concave. ¢ minoris mandibule bre- 
viores, minus arcuate, dentibus distantioribus, primo lato apice sinuato. Epistoma medio producto-lobatum, 
lobo quadrato, apice sinuato, Thorax valde transversus, apud angulos anticos acutos latissimus. 
Q mandibule parve. LEpistoma medio angulato-productum. Thorax quoad formam variabilis, pleramque minus 
transversus, angulis anticis minus productis.
