traversing the triangle, and there are 2 or 8 cells iinmediatelv there- 

 after with 2 rows following for a oonsideral)le space, increasing to 3 

 and to -J: at wing margin. In the hind wing the triangle is open, there 

 is but a single cul)ito-anal crossvein before it, vein Cu^ arises from its 

 outer side, distinctly apart from 6^^/21 the anal loop is rather short, with 

 a single row of cells along either side its t)i.secting v(Mn except at the 

 "heel*" where there is a single additional <ell 

 interpolated. 



The hind lobe of the prothorax is produced in ;i 

 moderate quadrangular undivided posterior lobe fig. 5.— tekminal 

 fringed with tawny hairs. ^r-'r^^TS 



The vulvar lamina of the female is elongate tri- of murathykia 

 angular, rounded on the tip, which nearh' attains ''*'-'"^'^- 

 the level of the apex of the .slightly produced stenunn of the ninth 

 segment. 



This species was bred at Silo Paulo, Brazil, bvMr. Adolph llempcl, 

 on October 8, 1897, and a number of adult specimens were captured 

 at large at the same time and place. 



2^1/iiiph: Length 12 mm., abdomen 7 nun. hind femur :'...") nun.; 

 width of head 3.5 mm., of abdomen -1.5 mm. 



Body thick set; head highest in the rear, sloping forward, the large, 



bulging eyes capping the antero-lateral angles, broadly rounded l)ehind 



the eyes to the nearl}^ straight hind margin. Labium moderate, the 



hinge reaching posteriorly beyond the bases of the fore legs. Mentum 



wide, median lobe very prominent, its border not crenate, but armed 



with spinules rather regularly placed and with a pair of spinules close 



together at the tip, which is not produced forward to form a distinct 



tooth; mental set;e H each side, the tifth (counting 



gyp^^^ from the side) longest. Lateral seta^ ('». Teeth

TH^Ri'pTi'i.T' reaching posteriorly as far as the middle of the sixth 



abdominal segment. Tarsal claws increasing markedly 



in length posteriorly, those of the hind tarsi being twice as long as 



those of the fore tarsi. 



Abdomen (tig. 1) triquetral, ovate, widest on segment »>, tapering 

 gradually to the ninth, which is suddenly narrower. Tenth segment 

 short, annular, almost included in the ai)ex of the ninth. Dorsjil hooks 

 wanting. Lateral spines on segments 8 and ;> alwut a third as long as 

 the segments. Appendages as long as segments t> and 10 together, 

 superior and inferiors of eciual length, laterals a little more than half 



as long. 



This species clearly belongs to Mk-ndlujr'ui, but 1 am not sure it 

 may not have V)een described already under some of the older names,
