MUSCULATURE OF DIPTERA — SMART 337 



Drosophila in Demerec's (1950) "Biology of Drosophila" are noted. 

 Indications of the synonymy in respect of the terminologies of Snod- 

 grass (1935), Berlese (1909), and of Weber (1928 and 1933) can 

 be found in Niiesch (1953).*

A. TERGAL 



1. Dorsal longitudinal. 



2. Oblique dorsal

• Not present in Anisopus. 



A. TERGAL MUSCLES. 



I. DORSAL LONGITUDINAL (INDIRECT FLIGHT) MUSCLES (fIG. 2). 



Other names are: Longitudinal median muscles (Snodgrass), dor- 

 sal muscles (Ritter), median dorsal muscles (Maki), longitudinal 

 dorsal muscles (Bonhag), dorsal median muscles (Miller in Demerec). 



Maki (1938) distinguished between "internal median dorsal" and 

 "external median dorsal" muscles. In Diptera he found the latter 

 present only in Orthellia (Muscidae). This distinction is very dubious. 



4 I have been unable to incorporate much information from Kelsey's (June, 

 1957) paper on the pterothorax of Cory dolus. I received the paper in August 

 1957 but had to proceed on a collecting expedition to New Guinea that same 

 month.
