Of this species we possess two males and three females from Mexico, and I have 
seen four others belonging to the Vienna Museum, one of these latter being labelled 
“California.” It has the head more regularly convex between the eyes than in 
Z. fusciventris.

The numerous specimens from Guatemala and Panama which are here referred to 
Z. micantula are a little smaller than the only South-American specimen of that insect 
before me. They measure from 11-13 millim. in length, and 53-64 millim. in breadth, 
in this respect agreeing with the dimensions given by Mayr”. Z. métnuscula, Uhler, 
seems to belong to the same species: it is described * as having “‘a purplish tint 
over its olive-brown upper surface; the costal margin pale testaceous; the underside 
of the body, together with the legs, testaceous, the latter variously banded with brown.” 
Dr. Aurivillius informs me that there are specimens of Z. micantula, Stal, from 
Honduras, in the Stockholm Museum. The present insect is much smaller than any 
of the other Central-American members of the genus. It resembles Z. elliptica in 
general shape, being considerably narrowed forwards; the head is shaped very much 
as in Z. minor. ‘The number of membrane-nervures varies from 6—9 in specimens from 
the same locality, showing that no reliance can be placed on one of the chief 
characters (9 nervures, instead of 8) used by Buchanan-White to distinguish his 
Z. zelotypus*, The South-American (Argentine) example (?) mentioned has the 
abdomen more pointed at the tip, and the membrane a little more produced, than any 
of our specimens.
