form 35 of the species than with the type form from Ecuador in all of 

 the differences separating these two given in Biologia Centrali- Ameri- 

 cana, Neuroptera, page 226. Ocellata dentiens differs from both in 

 the greater prominence of the proximal inferior tooth of the superior 

 appendages and from ocellata quicha in the brown stripes of the sides 

 of the thorax being wider than shown in B. C.-A. Neur. pi. IX, fig. 22. 

 The right front wing of one male from Bom Fim, and both front 

 wings of one female from Muniz Freire have the internal triangle 

 three-celled. Otherwise all five specimens agree with the venational 

 features given in the table on page 229. 



157. Micrathyria catenata sp. nov. 



d\ Lips yellow, free margin of labrum, inner (mesial) margins of 

 lateral labial lobes, and a median stripe on the middle lobes blackish. 

 Frons and clypeus pale green, the former metallic-blue superiorly and 

 extending down on to the anterior surface in the middle line, but not 

 on the sides. Vertex metallic-blue, its tip yellow. 



Thorax chiefly blackish-brown, the following pale green : a narrow 

 stripe on each side of the mid-dorsal carina, each confluent superiorly 

 with a transverse green stripe immediately in front of the antealar sinus 

 (which also is green), thus forming an inverted L; a narrow ante- 

 humeral stripe extending from the anterior mesepisternal margin half- 

 way up toward the antealar sinus ; a wider, sinuous, indistinct, broken 

 humeral stripe ; a still wider mesepimeral stripe and one in front of the 

 second lateral thoracic suture, both of which are interrupted a little 

 above mid-height, and are narrower above the interruption ; a met- 

 epimeral stripe bordering the latero-ventral suture and nearly half as 

 wide as its sclerite. 



Abdomen narrowed from 2 to the base of 4, thence widening grad- 

 ually to the hind end of 7 (2 mm.), thence narrowing to 10, blackish ; 

 a pale green stripe on each side of the dorsum of 3-6, half as wide (or 

 less) as the side of the dorsum on which it lies, interrupted on each 

 segment by the additional transverse carina or suture, and reaching 

 back to at least half the length of each segment. 7 with a large green 

 spot on each side, separated from its fellow of the opposite side by a 

 dark interval one-third its own width, reaching from anterior end to 

 four-fifths of the length of the segment. 



Superior appendages in dorsal view as long as 9 -f 10, black, slen- 



35 For which the name Micrathyria ocellata quicha (from that of a human tribe) 

 may be suggested.
