Machimus occidentalis (Hine)  

A male pupal case of this species was described by Dennis & Lavigne (1976a) under the heading " M. sp. either callidus (Williston)   or occidentalis (Hine)   ." The specimen was subsequently deposited in the United States National Museum. It is labeled "Sherman Hill Estates, Laramie, WY; VII–10–72; S. Dennis Collector.” We believe the pupal case is now correctly identified as M. occidentalis   .

The description should be modified to include the following: outer posterior antennal processes with flattened, basal, oval area toward dorsum; posterior labral keel apically tubercle­like; prothoracic spiracle tilted posteriorly; segment 9 with pair of long dorsal posterolateral processes, pair of slightly shorter ventral posterolateral processes (previously described as mediolateral processes), and pair of short ventromedian tuberclelike processes.
