MYZINE. 257 



An example from Venta de Zopilote in Guerrero (E. H. Smith) wants the yellow 

 marks on the pronotum and median segment, and it has the marks on the mesonotum 

 much smaller. It is also smaller, being only 15 millim. in length. The second 

 abdominal band may become obliterated.

Head closely and strongly punctured, densely covered with long dull fulvous hair; 

 the ocelli in pits ; a broad and deep longitudinal furrow over the antennae ; the inner 

 orbits of the eyes and the clypeus yellow ; the mandibles yellow, the apices ferruginous ; 

 the labrum brownish ; the apex of the clypeus almost transverse. Antennae stout ; the 

 apex reddish. The pro- and mesonotum moderately strongly, the pleurae still more 

 strongly, punctured. In front of the pronotum are two yellow marks, and the apex is 

 edged with yellow ; there is a curved yellow mark below the tegulae, and a smaller one 

 lower down below the hind wings ; there is a yellow mark on the apex of the meso- 

 notum, one across the scutellum, and one on the postscutellum ; the inner furrows on 

 the mesonotum are wide and deep. The median segment is very closely and rather 

 strongly punctured, except a smooth, impunctate, glabrous space at the sides, beneath 

 which is a curved yellow line. The mesonotum is sparsely covered with short dull 

 fulvous hair, the median segment more thickly with longer hair of the same colour; the 

 hair on the pleurae is paler. Abdomen shining, sparsely pilose ; the black ground-colour 

 with blue and violet reflections ; all the segments, except the last, banded at the apex 

 with yellow, the yellow at the sides turning backwards on the ventral surface ; close to 

 the yellow dorsal bands are yellow marks ; the segments above and beneath are sparsely 

 punctured. Legs black ; the four anterior tibiae in front and the fore tarsi yellow ; a 

 mark on the hind coxae, and one on the apex of the hind femora beneath, yellow ; the 

 femora bearing on the lower side long white hair, above densely covered with silvery 

 pubescence; the tarsi are also covered with a dense pubescence, their spines pale 

 fulvous ; the calcaria are pale. Wings clear hyaline, the apex infuscated ; the second
