 Parandra brunnea. 



13. Odontocolon curtum, new species 



Male: Front wing 6.6 to 6.7 mm. long; first segment of fiagellum 

 about 1.2 as long as second segment; all segments of fiagellum a little 

 shorter than usual; punctures on mesoscutum small, separated by 

 about 3 times their diameter; propodeal teeth about 0.3 as long as 

 their basal width; punctures on hind femur moderately dense above, 

 becoming sparse below the middle, near the lower edge separated by 

 about 5 times their diameter; second segment of middle tarsus about 

 2.7 as long as deep; fifth segment of hind tarsus about 1.1 as long as 

 second segment; second tergite polished except for weak, very fine 

 rugulosity basally, its punctures very fine, evenly distributed, sepa- 

 rated by about 0.8 the length of the hairs. 



Black. Clypeus and mandible sometimes largely ferruginous; 

 labrum fulvous; palpi fulvous to brown; tegula brownish fulvous to 

 blackish; legs fulvoferruginous, their coxae a little darkened basally, 

 fifth segment of front and middle tarsi and hind tarsus somewhat 

 infuscate, and hind tibia faintly infuscate; wings faintly infuscate. 



Female: Front wing 6.8 to 9.4 mm. long; fiagellum with 29 to 32 

 segments, its segments unusually short, its first segment about 1 .40 as 

 long as second ; head about 1 .03 as wide across temples as across eyes ; 

 punctures on temple of mixed medium and small sizes, separated by 

 about 3.5 their diameter; thorax about 2.40 as long as high; postero- 

 dorsal 0.3 ± of pronotum with small weak punctures that are sepa- 

 rated by about 2.5 their diameter; trough of pronotum with a few 

 weak, very short, transverse wrinkles, otherwise smooth; punctures on 

 mesoscutum small, weak, very sparse, in most areas separated by 5 

 or more times then- diameter; mesepimeron with moderately dense 

 hairs on its upper 0.45 ±, the rest bare or with few hairs; metapleurum 

 with moderately strong, irregularly oblique, rugosopunctation; petiolar 

 area about 0.45 as long as combined areola and basal area; propodeal 

 teeth about 0.6 as long as their basal width; hairs in first lateral area 

 sparse to moderately dense; hind femur about 1.80 as long as deep, the 

 punctures on its upper half rather small, rather sharp, and dense, 

 those just below middle somewhat larger and sparser, the lower 0.4 ± 

 of the femur almost without punctures; second segment of middle 

 tarsus about 1.5 as long as deep; fifth segment of hind tarsus about 1.38 

 as long as second segment; second tergite smooth, polished with its 

 basal 0.15± somewhat rugulose, its punctures very small, separated 

 by about 3 times the length of the hairs; ovipositor sheath about 1.45 

 as long as front wing.
