Head with interocular space a little less than half width of head, a 

 median depression over the frontal tubercles, occiput alutaceous and 

 finely punctate about the depression over the tubercles, a poorly 

 defined and narrow carina down the lower front, lower front more 

 densely punctate, head pale with the mouthparts edged with brown. 

 Antennae long wdth the basal and apical joints pale, the intermediate 

 ones brownish. Prothorax considerably vnder than long wdth slightly 

 curved sides and a shallow transverse depression, another shallow 

 median depression anteriorly, surface alutaceous and finely punctate, 

 entirely pale. Scutellum pale. Elytra with no signs of costae, densely, 

 confusedly and rather coarsely punctate, pale yellow, each elytron 

 with a piceous spot on the humerus and a smaller spot below it on the 

 side, these two spots sometimes confluent, a large spot below the 

 scutellum near the suture, a fourth spot on the side at the apical curve 

 and a fifth spot near the sutm-e and slightly above the apical curve spot. 

 Body beneath and legs entu-ely pale, the middle and hind tibiae with 

 a spine. Length 8.5-9.7 mm.; width 4.5-5 mm. 



Type, male, USNM 66848, from near Cot, Costa Rica, collected by 

 P. Knight, Sept. 22, 1937, on potato. 



Other localities: Coronado, Costa Rica, 1400-1600m. Nevermann, 

 collector; Carpentera, Costa Rica, Feb. 2, 1936, collected by Sofia and 

 C. H. Ballon, on Anona. 



Remarks: In coloration and sculpture this resembles the Peruvian 

 species, N. octosignata, but the Peruvian species lacks the small spot 

 on the side below the hmnerus; the antennae are not so long, and the 

 first tarsal joints of the middle and hind legs are shorter. In N. 

 decimsignata the antennae and the first tarsal joints of the middle legs 

 are longer than in any of the other large spotted species.
