302 Mr. T. I\ A. C'ockeicll — Descriptions and 



thorax above, more or less resembling the outline of a 

 medusa or jellyfish. The modified apical area of female 

 abdomen is rather small. This is easily known from 

 T. lieiKinthi by the wide interruption of the apical band on 

 first abdominal segment and the "wider stripes on meso- 

 thorax ; these latter are brond to the base (front), not 

 slender and thus clavate as in T. sublunatus, Ckll. 



Chalepogenus calcaratus (Cresson). 



The known distribution is greatly extended by males from 

 Sonsonate, Salvador, Aug. 24 {F. Knab), and Paraiso, 

 Panama Canal Zone, Jan. 16 (.1. Busck). 



In the southern part of the range there is more black on 

 the clypeus of the male. The species was described fi'om 

 Mexico. 



Chalepogenus glohulosus (Fiiese). 



Friese described this from a single male from an unknown 

 locality, calling it Tetrapedia glabvlosa. I have before me 

 a male from Taboga I., Panama, July (.-1. Busck), and a 

 female from Paraiso, Panama Canal Zone, May 11 {A. H. 

 Jennings). The female closely resembles the male, but 

 differs thus : face broader ; clypeus ferruginous ; front 

 ferruginous except an obscure median stripe, and a flame- 

 like upward extension (away fi'om orbit) of each lateral 

 matk ; liind legs with ferruginous scopa. In both sexes 

 the mesothorax has lateral as well as discal yellow stripes. 

 The male has no brown fringes on the abdominal segments, 

 but it agrees in general so well with Friese's description 

 that I believe it must be the same. 



Exomalopsis globosa (Fabricius). 



Females from Mavaguez, Porto Rico, Jan. 9 (C IV. 

 Hooker, 68). 



This species is readily known from the mainland 

 E. inanni and ze.vmenue by the dark reddish stigma. The 

 scopa of hind tarsi is very long and loose.
