Gl. palpalis zuellmani Austen. — Described in 1905. Differs 

 from type by having the frontal stripe pale ochraceous ; thoracic 

 markings much reduced, presenting a spotted appearance ; spot 

 behind humeral callus small, avoid or nearly circular; femora 

 pale, the dark blotches much reduced. 



There is also an unnamed variety which was at first desig- 

 nated Gl. palpalis var. tachinoides Westw., and was thought to 

 represent a fly which, when true specimens were obtained, was 

 recognized by Mr. Austen to be of specific rank ( Gl. tachinoides 

 Westw. [vide supra}), the variation from Gl. palpalis remain- 

 ing unnamed at last accounts received here, and I therefore set 

 it down for the purposes of this paper as 



Gl. palpalis var. a. — It is distinguished from Gl. palpalis 

 principally by its pale femora and a yellow median stripe on 

 the abdomen.* There is also another variation from the typical 

 Gl. palpalis which may be differentiated as follows : 



Gl. palpalis var. b. — Femora still paler than foregoing; palpi 

 pale except at tips ; abdomen reddish brown with the pale area 

 on second segment oblong, f
