382 W. L. DISTANT. 



This species is variable in the colour of the pronotum and scutellum, which in some 

 cases (as in the Colombian specimen here figured) are ochraceous, and Mr. H. H. 

 Smith has sent both the forms as taken in cop. (Mexico : Teapa). Another variation 

 in specimens from all localities is in an occasional ochraceous amiulation to the pos- 

 terior femora, as in the figure here given. Kirkaldy, whose type of M. pihsipes is 

 now in the British Museum, seems to have relied on the pilosity of the legs, as a 

 character of his species. It was mentioned in the diagnosis of M. atratum "legs 

 black and strongly pilose," and in the figure given of this species this character was 

 particularly portrayed. 



M. reuteri, Bergr., from Guiana (Ann. Soc. Ent. Belg., 54, p. 67, 1910) is also 

 evidently allied to this species.

A single specimen of this species has been received. It may prove to be another 

 variety of the preceding species, M. atratum, but requires recognition as an economic 

 pest.
