NO. 3548 ARADIDAE — KORMILEV 15 



Abdomen longer than width across segment VI (90:72.5); lateral 

 borders feebly convex from II to V; angularly produced on VI and 

 VII. Exterior borders of connexival segments II to V slightly con- 

 vex, making lateral borders look festooned. Connexival segment VI 

 trapezoidal, with postero-exterior angle rounded at tip; VII angu- 

 larly produced backward as far as the tip of hypopygium. Parater- 

 gites flat, fusiform, reaching to tip of hypopygium. Latter subcordate, 

 shorter than maximal width (15:19), divided by a transverse 

 furrow in upper and lower lobes. Upper lobe subtriangular, wath a 

 relatively narroAV median ridge; lower lobe semiglobose; both lobes 

 covered with incrusted, curled hairs. Spiracles from II to V ventral, 

 placed far from borders; VI to VIII lateral and visible from above. 



Color. — Ferruginous; base of antennal segment I, antennal 

 segment III, with exception of tip, and apical half of IV, yellow 

 brown. Round calloused spots on connexival segments III to VII 

 yellow. 



Measurements. — Total length 6.8 mm.; width of pronotum 2.0 

 mm.; width of abdomen 2.9 mm. 



HoLOTYPE. — Male, Callanga, Peru, 1300 m., F. Woytkowski col- 

 lector, Feb. 13, 1953 (USNM type 67588). 



Miorrhynchus angulatus, new species, is related to M. longipes 

 Champion and may be separated from the latter by the angularly 

 produced connexivum VI, which is rounded in M. longipes.

Male. — Elongate ovate; partially covered \^'ith curled, incrusted 

 hairs. 



Head longer than width across eyes (25:21). Anterior process 

 moderately stout, covered laterally with incrusted hairs; reaching 

 basal fourth of antennal segment I. Antenniferous tubercles short, 

 blunt, slightly divergent. Eyes semiglobose, protruding, but less 

 than in preceding species. Postocular borders convex; postocular 

 tubercles spiniform, placed fai- behind eyes, dii-ected sideways and a 

 httle backward. Vertex Anth V-shaped row of setigerous tubercles, 

 and laterad of them Avith two (1 + 1) ovate callous spots. Antennae 

 long, more than three times as long as head (80:25); proportions of 

 antennal segments 28:12.5:28:11.5. Rostrum reaching hindborder 

 of rostral groove, latter closed posteriorly. 



Pronotum shorter than width across humeri (35:53). Forelobe 

 much narrower than hindlobe (36:53). Collar wide, slightly sinuate 

 anteriorly. Anterolateral angles rounded; lateral borders convex on 

 the forelobe, strongly convex on the hindlobe. Hindborder slightly
