Related to R. multiguttata Alexander (Guatemala) and in my key 

 to the species of this genus^ it would run down to this form. It 

 differs widely in its wing-pattern which resembles that of certain 

 members of the suhpectinata group {annulicornis Enderlein, schwarzi 

 Alexander) in the prominent rounded dark spots at the base of the 

 sector and at the stigma. The thoracic pattern, especially the 

 velvety black postnotum, separates this species off from any of the 

 described forms. 



This species is named in honor of Mr. Raymond C. Shannon, 

 assistant to Mr. Knab in the Department of Dipterology at Wash- 

 ington, Avho collected the type and who has reared many interesting 

 cranefiies. 



Tribe Antochini.

Paratype, cf, topotypic. 



Related to T. flavithorax Wiedemann in the bright colored thorax 

 and dark wings; it is a smaller species with the wings much lighter 

 colored, the stigma smaller and more distinct, the femora with the 

 bases brighter colored, not entirely jet-black. In flavithorax the 

 legs are stout and covered with long, conspicuous hairs, while in 

 rubescens the hairs are not conspicuous; the basal tarsal segments of 

 flavithorax are light j^ellow, conspicuously lighter colored than the
