RECLASSIFICATION OF MICROG ASTERINI 203 



small ; 1st abscissa of the radius very long. Ovipositor much longer than the hind tibia. 

 Hypopygium membranous at sides and here with numerous longitudinal creases. 



Type-species : Dasylagon aegeriae Muesebeck (by original designation). 



Seen within the context of the limited amount of New World material that I have 

 had at my disposal, this genus seems to be isolated on the structure of the basal 

 tergites. In wing venation it shows much affinity with Promicrogaster but this 

 genus differs from Dasylagon not only on the structure of the gaster but also in 

 having the antennal scape longer, the head and mouth parts lengthened and the 

 glossa deeply forked. 



Muesebeck described two species in Dasylagon — aegeriae and simulans. He has 

 been kind enough to lend me a male and female paratype of aegeriae. I have also a 

 second species that I provisionally identify as a colour variant of simulans. 



Key to Species 

 Females and Males 



A 9- Entire body black ; anterior to the areola a short keel that separates the two large 

 horizontal areas ; 1st abscissa of the discoideus not longer than the nervulus ; 

 areolet larger ; radius less downcurved at apex ; disc of scutellum with weaker 

 punctation ; spines along upper part of hind tibia denser (in fact, very dense), 

 more numerous and less upstanding ; hind coxa black ; tergite 2 considerably 

 more transverse (Text-fig. 235). Gaster of o" entirely black . aegeriae Muesebeck 35 



Colombia. Bred from unidentified Aegeriid. 

 Type in U.S. National Museum. 



B $. Gaster bright red ; anterior to the areola a poorly defined, excavate area 

 separated from the areola by a transverse keel (the areola thus virtually occupying 

 full length of the propodeum) ; 1st abscissa of the discoideus distinctly longer than 

 the nervulus ; areolet smaller ; radius strongly downcurved at apex ; disc of 

 scutellum with stronger punctation ; spines along upper part of hind tibia less 

 numerous, more upstanding ; hind coxa red ; tergite 2 less transverse. Gaster 

 of o* blackened on nearly apical half . . simulans Muesebeck, 36 colour var? 



Honduras. Type in U.S. National Museum. 



Brazil: Bahia, 1926, 1 o\ 1 $, bred from Sicalodes falcata Felder (Thyrididae). 

 In British Museum (Nat. Hist.). 

 According to Muesebeck, simulans has the body entirely black with the legs 

 reddish yellow except that the coxae and trochanters and the hind tarsi are black. 

 In aegeriae, the hind femur and hind tibia are red with the hind tarsus contrastingly 

 blackened. 



SENDAPHNE gen. n. 



Type-species : Sendaphne olearus sp.n. 



Species of very slender build. Scape rather long (Text-fig. 245). Pronotum with well 

 defined dorsal furrow. Mesoscutum and disc of scutellum highly polished and with at most a 

 very superficial punctation. Lateral polished zone of scutellum triangularly extended forwards
