face; tarsi of middle and hind legs brownish. Ovipositor reddish 

 brown, sheaths blackish. 



H. muesebecki also differs from oculatus in the shape of the occipital 

 carina and of the eyes. Viewed laterall}^ the occipital carina is raised 

 or flanged in oculatus but not in this new species. The eye of ocu- 

 latus seems to be widest distinctly before the middle, while in muese- 

 becki it seems widest just before or almost at the middle (fig. \,e,f). 



Described from a unique female collected at Rio de Janeiro, Brazil, 

 September 1938 by R. C. Shannon. This specimen is in the 

 U. S. National Museum collection under type No. 62053. 



This new species is named in honor of C. F. W. Muescbeck, who, 

 despite his heavy schedule and many obligations, still takes time to 

 aid or advise the many who ask his assistance. 



Habryllia convergens (Cushman), new combination 



Brachycyrlus convergens Cushman, 1936, Proc. U. S. Nat. Mas., vol. 84, pp. 18, 

 20, fig. 2. 



Cushman's description of this species is so complete that little more 

 need be done than to stress certain characters. This is the only 

 species with annulated antennae known to me. Like H. muesebecki, 

 it is stouter in general conformation than the remaining species in the 

 genus. Further discussion will be found under //. cosmeta, new 

 species. 



Thus far this species is known only from the unique female taken 

 at Cano Saddle, Gatun Lake, Panamd. 



Habryllia cosmeta, new species 



Figure l,a 



Holotype, female: Length barely 5 mm.; forewing 3.5 mm.; 

 antenna 4.55 mm.; ovipositor sheaths 1 mm. 



Head polished, with minute, scarcely visible punctures on the face; 

 eyes somewhat convergent anteriorly, wealdy emarginate; malar space 

 barely one-half the basal width of mandible; temples, viewed dorsally, 

 about one-half the width of the eye; ocellar triangle transverse; 

 antennal flagellum with 30 segments, the basal segment fully as long 

 as the second and third combined. 



Thorax at least as deep as, or a little deeper than, long; polished and 

 sparsely punctate on the mesoscutum and mesopleura; propodeum, 

 except polished metapleura, with more or less of the other areas 

 appearing finely granular, spiracles small, elongate-oval, areola and 

 petiolar area confluent, first and second lateral basal areas confluent; 

 scutellum longer than wide, lateral carinae reaching apex; postscutel-
