M. platypterus. 



General color a darker brown than in lineatus. The dorsal 

 margin of tegmina a grayish brown, with no yellow stripe along 

 the scapular area. The ninth abdominal segment of the male 

 has on the under (ventral) side a mid-stripe of black (Fig. 25a), 

 which is not present in lineatus.

Female 35-40 10-11 24-25 17.6-20.6 



Male 23-26 11-12.5 19-21 15 -16.5 



This species has been taken by Professor Morse at Thompson 

 in company with lineatus, but is much less common, the female 

 hard to flush and consequently difficult to secure. 



cedipodin^:. 



Head with the vertex sloping downward, the face nearly 

 vertical, rounded where joined to the vertex. Eyes rather small, 

 shorter than the portion of the cheek below their orbits. An- 

 tennae linear or sub-linear, situated above the middle of the eyes, 

 sometimes almost above the eyes themselves. Disk of the prono- 

 tum with the rear margin much wider than the anterior margin. 

 The lateral carinas usually not distinct, the median carina wholly 

 or at least partly crested, and cut by one or two sulci (except 

 in Arphia, in which the median carina is entire). The tegmina 

 and wings fully developed, usually bright-colored, and with a 

 dark median band.
