aside from the arches, marked with fuscous, the dorsal surface of the 

 caudal tibiae and the marginal spurs Aveakly washed with the same 

 shade. 



Length of body, 7 mm.; length of pronotum, 1.4 mm.; greatest 

 width of pronotum (caudad) 2 mm.; length of tegmen, 6 mm.; great- 

 est width of dorsum of tegmen, 2.5 mm.; length of wings distad of 

 tegmen, 4.6 mm.; length of caudal femur, 5.8. 



The type of this species is unique. 

 Anaxipha fistulator n. sp. (PI. II, figs. 63-66.) 



Allied to A. championi (Saussure), from Panama, but differing in 

 the more elongate palpi, the distal joint of which is markedly elongate 

 and obliquely truncate distad, in the more sharplj^ inflated and then 

 narrowed cephalic tibise, the differently shaped lateral lobes of the 

 pronotum and in the more slender caudal femora. When compared 

 with A. strmnenticia, described below, fistulator is seen to be quite 

 close, but the latter differs in its distinctly larger size, somewhat dif- 

 ferently shaped palpi and cephalic tibiae and has the pronotum more 

 strongly transverse. 



Type: cf ; Igarape-assu, State of Para, Brazil. (H. S. Parish.) 

 [Acad. Nat. Sci. Phila., T^De no. 5341.] 



Size quite large (for the genus) : form subdepressed, the tegmina 

 broader than the body, wings long caudate: surface of the body 

 rather thickly covered with hairs, many of those of the head and 

 pronotum chaetiform. Head broad sub-cordiform in outline when 

 seen from the cephalic aspect, the greatest width across the eyes but 

 faintly less than the length, the buccal region quite narrow, the 

 occipital outline arcuate transversely; in lateral aspect the dorsum 

 of the head is seen to be strongly, but uniformly declivent to the inter- 

 antennal protulDerance, which broadly rounds caudad to the clypeal 

 suture: eyes moderately exserted and well rounded when seen from 

 the dorsum, in basal outline short and broad ovate: antennae incom- 

 plete, the proximal joint broad: palpi slender, elongate; third joint 

 gently arcuate, faintly shorter than the fifth joint; fourth joint about 

 three-fifths as long as the fifth joint, the latter trumpet-shaped, the 

 distal margin obliquely truncate. Pronotum weakly sellate, strongly 

 narrowing cephalad, the pronotum distinctly transverse, the greatest 

 caudal width more than twice that of the cephalic margin of the disk 

 and equal to one and one-half times the length of the pronotal disk, 

 the dorsum broadly rounding into the lateral lobes: cephalic margin 

 of the disk subtruncate, rounding into that of the lateral lobes; caudal 

 margin of the disk truncate; medio-longituchnal sulcus indicated
