NEOBROTICA AND RELATED GENERA — BLAKE 343 



Head wide, with the interocular space more than half width of 

 head, occiput smooth and shining with a median depression, piceous 

 to the antennal sockets, lower front pale yellow to below the excava- 

 tion, then piceous with a piceous mouth; in male lower front below 

 a broadly projecting shelf edged with long hairs under each antennal 

 socket, deeply excavated, and on either side a long strongly cmwed 

 spine. Antennae long, in the male the basal joint very long, second 

 joint knoblike and short, third broad and excavated at the end, 

 fourth broad and excavated at the base, remaining joints long and 

 subequal, pale j^ellow with the fii'st three joints with a piceous spot on 

 the outside, joints five to eight deep brown, tip of terminal joint also 

 dark. Prothorax almost rectangular, approximately twice as broad 

 as long, impunctate, shining pale yellow. Scutellum pale. Elytra 

 broad and a little wider at apical end, humeri well marked with a 

 deep intrahumeral sulcus; surface irregularly costate, the intervals 

 rugose with obsolete geminate-striate punctation, shining, pale 

 yellow; a broad deep blue fascia extending across the base, sometimes 

 with a small pale spot in it, and another broad dark blue fascia near 

 the apex and interrupted at the sutm'e. Body beneath and legs 

 entirely pale yellow, anterior coxal cavities open, claws appendiculate, 

 all tibiae with a spine, front tibiae in the male stout and the fii'st 

 basal joint of tarsi cylindrical. Length 5.2-6 mm.; width 2.6-2.8 mm. 



Type, male, MCZ 30677, Port Limon, Costa Rica, collected by 

 P. J. Darlington, May 9, 1959 ; one paratype, male, USNM, same locality. 



Remarks: This species is closely related to denticornis (Jacoby), 

 but it has a different elytral pattern and not so well marked elytral 

 costae or so deep punctation. The head and prothorax are wider 

 too. In the structure of the antennae and the excavated front of 

 head in the male the two species are similar.

About 7 mm. in length, elongate oblong oval, faintly shining, the 

 prothorax nearly twice as wide as long with a transverse sulcus, the 

 elytra strongly costate to apical curve, and the intervals geminate 

 striate, pale yellow brown; the elytra with reddish brown markings, 

 consisting of a lateral vitta from the humerus nearly to apex, a spot 

 in the middle near the base, a median fascia connected both on the 

 side and at suture with a curved fascia near the apex, body beneath 

 and legs pale, the tibiae slightly brownish, this description being of 

 the female, the male unknown. 



Head with interocular space half width of head, a rounded median 

 depression over the frontal tubercles, no carina between antennal 

 sockets or down front but the lower front depressed in the female.
