_ A Tropical-American genus containing some of the finest species of the Family 
Cassidide. The males of all the species of Dolichotoma known to me have the 
antenne much longer than in the females, the apical joint with numerous very long 
projecting hairs at the tip beneath, the preceding four joints also with a few shorter 
hairs at the same place. The hairy apical joint is mentioned by Boheman, though he 
was not aware that it was a sexual character; it has been overlooked by Chapuis and 
Baly. Dolichotoma is chiefly distinguished from Canistra, a genus not represented 
within our limits, by having the joints 1-6 (instead of 1-5) of the antenne short, 
shining, and subglabrous, the other joints being elongate, opaque, and very finely, 
densely pubescent. 
1. Dolichotoma bisbiplagiata. (Tab. V. figg. 16, ¢; 16a, antenna, ¢ .) 
Dolichotoma bisbiplagiata, Boh. Cat. Col. Ins. Brit. Mus. ix. p. 81°; Monogr. Cassid. iv. p. 807. 
Hab, GuatemMata (Deby, in Mus. Brit.17), Cubilguitz in Vera Paz (Champion),

Apparently confined to the forest-region of the Atlantic slope of Guatemala, and to 
the “ tierra caliente.”

Hab. Guatemaa (Scherzer, in Mus. Brit.) ; Nicaragua (coll. Baly1, Sallé), Chon- 
tales (elt, Janson) ; Costa Rica (Sallé, Van Patten). 
This insect appears to be not uncommon in Nicaragua and Costa Rica. The colour 
of the upper surface varies from greenish-eneous to bluish-black or black. The 
margins of the elytra are much more broadly expanded than in the allied D. princeps 
and D. biplagiata, Boh., and they have a large rounded sanguineous patch a little
