SMICRA. 91 



In size, coloration, and arrangement of the markings, this species agrees with S. dorsi- 

 vittata, except that all the black marks are longer and broader, and in addition to those 

 present on S. dorsivittata there is a small black mark immediately behind the teguhe, 

 one on either side behind the scutellum, and there is a black line on the depressed 

 space on the mesopleura ; the head is longer and thicker, the posterior coxae broader 

 and shorter compared to the femora, being, with the trochanters, shorter than they ; 

 while with S. dorsivittata they are longer than the femora ; the antennae are, if any 

 thing, shorter and thicker, and the third joint is longer compared to the fourth ; the 

 abdomen is also a little shorter. The male I have not seen.

Hab. Panama, Bugaba (Champion). 



Head and thorax densely covered with long black hair ; hair on the abdomen shorter 

 and thinner. Antennae thick, the flagellum of nearly uniform thickness, closely covered 

 with a pale pubescence ; third joint nearly one half longer than the fourth ; last three 

 joints closely united ; scape slightly bent at the base, scarcely keeled on the lower side. 

 Head broad, the excavation above the antennae shallow ; behind the head is black ; a 

 narrow black line runs from the anterior ocellus to this black portion, and there is a 

 triangular black mark above the antennae. There is a small black mark in front of 

 pronotum. The space between the prothorax and mesothorax laterally and between 

 the latter and metathorax black ; the shallow space on the mesopleura for the greater 

 part black. The edge of the mesonotum in front, the borders of the middle lobe to the 

 scutellum, the base of the scutellum, and a longitudinal line running from the last to 

 the line at base of the mesonotum black ; these lines are narrow and of nearly equal width. 

 There is a small black mark on the lateral lobe of the mesonotum, a longitudinal narrow 

 line on the scutellum ; the sides of the latter and an oblong mark on the posterior coxae 

 black. Scutellum margined behind, and narrowed to a blunt point at the. apex. Reticu- 

 lations on the metanotum indistinct ; above it has a blistered appearance. Petiole thick, 

 one half longer than broad, shorter than the metathorax. Posterior coxae with the 

 trochanters as long as the femora. Femoral teeth very minute and closely set, forming 

 a serrated edge. Abdomen a little longer than the head and thorax together, the apex 

 acuminate, with the ovipositor projecting, black. Nervures on the wing fuscous. 



The three narrow continuous lines on the mesonotum and the rufous abdomen variegated 

 with yellow separate this distinct species from the other yellow forms. The arrange- 

 ment of the black lines and spots on the thorax is nearly the same in S. marice, Eiley ; 

 but that has the base of the metathorax black, and the abdomen of the same colour as 

 the thorax, and with six black bands on the back.
