c. Chromocryptus planosae mesorufus Cuslunan, new status 



Chromocryptus mesorufus Cushman, 1930, Proc. U.S. Nat. Mus., vol. 76, art. 25, 

 p. 2; 9. Type: 9, Cuernavaca, Mexico (Washington). 



In color, this subspecies is much like vandykei, differing as stated 

 in the key. 



Specimen: 9, 40 km. southeast of Puebla, Mexico, Dec. 30, 1940, 

 G. E. Bohart (San Francisco). 



11. Lanugo, new genus 



Figure 313,b 



Front wing 5.0 to 12.3 mm. long; body of moderate build to rather 

 stout, mat (rarely subpolished) and with dense short hairs; frons un- 

 armed; clypeus of moderate size, moderatel}^ to strongly convex, 

 its apical margin truncate or arcuate, without a median tooth; mes- 

 oscutum moderately convex, strongly mat to subpolished or polished, 

 its punctures dense or very dense; notaulus moderately strong to 

 weak, usually reaching almost to center of mesoscutum; epomia 

 long, rather strong; propodeum rather strongly convex, its transverse 

 carinae strong, complete or the apical one weak or interrupted medi- 

 ally; apical transverse carina of propodeum forming very weak to 

 moderately strong sublateral crests, mesad of the crests bowed or 

 tm-ned strongly forward; propodeal spiracle elongate; areolet penta- 

 gonal, its intercubiti rather strongly convergent and its front side 

 shorter than mesal side; ramellus absent or rudimentary; nervulus 

 opposite or a little basad of basal vein; mediella almost straight; 

 nervellus broken near its lower 0.3; axillus close to anal margin; first 

 abdominal segment with its spiracle far behind the middle, its post- 

 petiole strongly expanded, rather strongly convex above; first tergite 

 usually with a weak subbasal lateral tooth, its ventrolateral carina 

 strong and sharp in females, usually absent in males, its dorsolateral 

 carina usually complete but blunt in females, obsolete in males, its 

 median dorsal carinae traceable in females to basal part of post- 

 petiole but very blunt and faint; second tergite mat, with very dense 

 fine punctures and short very dense hairs, especially in females; 

 tergite 7 not marked with white; ovipositor sheath about 0.5 as 

 long as front wing; ovipositor straight, compressed, its tip as in fig- 

 ures 329,b to 329,h. 



The generic name is from the Latin word lanugo, meaning soft, 

 downy hair, in reference to the fine, dense body hair characteristic 

 of the genus. 



Some of the species of this genus have formerl}'- been included 

 in Compsocryptus , to which they bear a superficial resemblance. La- 

 nugo differs from Compsocryptus in having a moderately short, straight
