The species now known to be referable to Grabhamia may be 

 separated on the following genitalic characters : 



Synopsis of Species of Grabhamia. 



Side piece without an outer lobe. 



Side piece without an inner lobe, a long row of cilia in its place triseriatus. 



Side piece with a rounded, prominent inner lobe. 



Inner lobe with long hairs surpassing the harpe. 



Filament of harpe as long as basal part varipalpus. 



Filament of harpe much shorter than basal part atropalpus. 



Inner lobe with short hairs, not reaching the harpe. 



Clasp filament hardly inflated sollicitans. 



Clasp filament distinctly inflated mitchella?. 



Side piece with the outer lobe developed. 



Inner lobe of side piece with a long, stout spine. 



( cantans.-" 

 Basal part of harpe simple ^ cantator. 



Basal part of harpe with an angle or projection bearing a seta. 



Inner lobe with two stout spines besides the basal one impiger. 



Inner lobe without such spines pullatus. 



Inner lobe of side piece without spines, setose only. 



Outer lobe projecting, separate, the side piece subcorneal. 

 Filament of harpe about half as long as basal part. 



Filament slender, pointed canadensis. 



Filament broad, spathulate pretans. 



Filament of harpe as long as the basal part. 



Harpago broad, plate-like dupreei. 



Harpago concave with acuminate bent tip. 



Outer lobe projecting laterally squamiger. 



Outer lobe projecting apically curriei. 



Outer lobe continued along side piece to base, making the side piece broad 

 and subquadrate. 

 Inner lobe normal, small, subprominent, with short hairs moderately 

 dense 

 Basal part of harpe very long, nearly equalling the side piece in 



length trichurus. 



Basal part of harpe less long, but still equalling half of the side 



piece lazarensis. 



Basal past of the harpe not equalling half of the side piece. 



Filament of harpe broad, spathulate punctor. 



f aestivalis. f 

 Filament of harpe narrow, slender j tl q v ittatus. 



Inner lobe not so formed. 



* The genitalia of cantans and cantator are alike. 



fl have only Professor Smith's small figure of the genitalia of trivittatus and 

 am unable to distingu ; sh cestivalis therefrom.
