MYZINE. 255 



finely punctured; the pygidium longitudinally striolate, almost glabrous, the apex 

 fiery-red ; a band on the first segment, incised at the base and apex, two large marks on 

 the second, and continuous bands on the third, fourth, and fifth segments, bright yellow ; 

 beneath there are two pale yellow spots on the second and two lines on the third and 

 fourth segments ; the ventral segments at the apex bear long white hair. The wings 

 are hyaline, with the margin infuscated from the basal nervure to the apex of the radial 

 cellule, and the nervures pale testaceous. The legs have a yellow line on the fore tibiae, 

 and the four anterior femora at the base behind are yellow ; they are covered with long 

 silvery hair ; the calcaria are white ; the fore tarsi and also the spines on the femora, 

 are ferruginous. 



We have also received a specimen of a larger form from Paraiso, Guatemala 

 (Champion) (14 millim.). It has the scape of the antennas entirely black; on either 

 side of the clypeus is a yellow mark, separated from the yellow orbital line ; there is a 

 broad yellow mark over the antenna? ; on the vertex behind the eyes is an elongated 

 line, the centre being without yellow ; there are only two somewhat triangular marks 

 on the pronotum ; the mark on the scutellum is much larger, and there is a small mark 

 on the sides at the base ; there is a somewhat triangular mark on the base of the 

 median segment, besides the two large lateral marks ; there is only one yellow mark 

 on the pleurae ; the marks on the abdomen are much as in the type, but there is no 

 line on the fifth segment ; there is a yellow mark on the hind coxae and femora. 



An example from Pena Blanca, Panama, has only a small yellow mark on the centre 

 of the vertex, and only one mark on the mesopleurae. 



A specimen from Capetillo has only the inner orbits of the eye yellow and no mark 

 on the scutellum ; two small yellow marks on the pronotum, and only one mark on the 

 median segment, the pleurae being entirely black ; only one yellow mark on the meso- 

 pleurae and none on the coxae, the front legs being also devoid of yellow ; the second 

 abdominal segment wants the yellow, and the yellow on the fourth and fifth segments 

 is interrupted in the middle.

Head closely and strongly punctured, the punctures on the vertex more widely 

 separated ; densely covered with long grey hair ; the inner orbits of the eyes yellow ; 

 the mandibles slightly ferruginous before the apex. The scape of the anteryiae shining, 

 bearing large punctures, and beneath with long white hair ; the flagellum covered with a 

 pale pile, the third and fourth joints subequal. The prothorax covered with long grey 

 hair, closely and finely punctured ; the mesonotum more strongly and not so closely 

 punctured ; the mesopleurae more coarsely punctured ; the median segment opaque,
