Paraspiiecodes, Smith. 



Siniihir to Ilalictus, but with head and thorax black and 

 abdomen red or Largely so. Males with clypeus ytdlow, 

 except at sides ai)Ove. Tliis genus does not differ from 

 Jia/ic(ics ii\ any good structural character, and its separation 

 is only justified by the fact that it includes a compact and 

 easily recognized group of species. In his generic aiagnosis 

 Smith says that the first r. n. always meets the second t. c. ; 

 but this is not invariably the case. So far as I know, the 

 hind spur of the female is always witliout spines or teeth. 

 The following table separates Smith's species : —
