in the overhanging vegetation. In my dried material the ab- 
domen has remained a lirilliant red. 
Neoneura denticulata new species (Figs. 10, 44, 45 and S3.) 
Abdomen, cf" 25 mm.; hind wing, cf 17. 
cf . — Colors teneral and obscure; genae, labrum, rhinarium, nasus and frons 
in front pale brown, labrum more j^ellowish, nasus with extensive obscure 
darker brown markings. Head above dull j'ellowish brown, marked with black 
as follows: a stemless trident in front of the median ocellus; a short bar 
forward and inward from the antenna to the front edge of the frons; a sm all 
spot behind the median ocellus and on each side on the inner side of each lateral 
ocellus; a short bar or spot between the median ocellus and the antenna; a 
transverse bar behind the lateral ocelli just in front of the occipital crest, which 
is produced outward and forward on either side in a broken bar or stripe to the 
eye; a round spot at either end of the occipital crest, more or less connected 
with a black transverse bar on either side, on the extreme posterior edge of the 
head in dorsal view, which does not reach the ej'e; in the large pale area, on 
either side anterior to this transverse bar, is a large, centrally located rounded 
spot. Antenna brown, second joint darker, distal extremity pale. Rear of 
head pale brown, black or darker about the foramen. 
Prothorax pale yellowish brown with extensive obscure darker markings; 
front lobe with the extreme front border pale, an obscure transverse bar just 
posterior to this, and a posterior spot on either side; middle lobe with the 
longitudinal median line darker, and a large indefinite obscure area on either 
side the full length of the lobe, but not reaching the lateral margin: hind lobe 
with the posterior edge and the lateral extremities pale, remainder brown, 
enclosing on either side in front a transverse pale spot. Propleuron brown, 
darker margined above and in front. 
Thorax brovm, mesepisternum yellowish, tending to red, markings brown 
and black, obscure. 
Abdomen yellow, sparsely marked, segment one with the usual dorsal 
basal black spot; two to six apically narrowly dark ringed; eight to ten with 
some evidence of dark markings. 
Legs light yellowish brown, femora and tibiae with scarcely defined scattered 
brown spots; tooth on tarsal claw, weak, not quite as inconspicuous as in 
maria, but much smaller than in mariana. 
^^'ings clear; stigma pale brown, covering slightly less than one cell, its 
costal length slightly more than twice its width. In the right hind wing the 
marginal cell posterior to the subquadrangle is divided by a transverse cross- 
vein near its mid-length. 
Type . — Teneral cf ; Iquito.s, Peru; Staiidinger; Coll. ^Nlu.seum 
of Comparative Zoology. The specimen is in poor condition and 
only the distinct abdominal appendages justif}' its description 
and designation as a type. 
Undoubtedly the color of the adult will prove to be similar to 
mariana, the head and thorax largely dark, and the abdomen
