division of the antennas. Below there are two small tubercles placed obliquely 

 one below the other and surmounted by a little hair, and on the vertex four 

 tubercles arranged transversely, the outer ones larger and bearing a hair. The 

 dorsal part and the sides of the thorax bear some small hairs. The abdomen, 

 consisting of seven segments, presents on the posterior thirds of each of the 

 first six a circular series of stiff bristles, unequal in length, thick at their base 

 and directed backwards. The last segment is small and ends in a small crown of 

 six conical diverging teeth, the two upper ones a Httle smaller than the others. 

 Rather near the anterior border of the thorax two obtuse protuberances arc seen, 

 somewhat more excavated and striated at the summit, crossed by an oblique fur- 

 row and inside showing a depression, the thoracic spiracles of the nymph. There 

 are also visible the very conspicuous marks of six abdominal spiracles; they are 

 situated laterally on the first six segments. 



It is conceivable that the tubercles, the hairs, and the bristles with which this 

 pupa is armed, are very useful when it wants to move or to reach the open air in 

 order that the perfect insect should not be hindered in the act of eclosion. In 

 the eclosion the shell of the pupa splits all along the median and dorsal side of 

 the thorax. 



Beling also describes the pupa of Ilcematopota pluvialis. 



Pupa. — 10 to 13 mm. in length, about 2.2 mm. in width, cylindrically rounded, 

 of a dirty brownish yellow color, slightly shining, somewhat narrowed behind. 

 Below the two small front teeth placed beside one another, and above the frontal 

 margin two small tubercles, not much farther distant from one another, and 

 each bearing a long bristle. Above this tubercle, som.ewhat distant from it, is 

 another separate hair, and, in addition, on each side of the thorax are two hairs, 

 one directly located behind the other. Abdomen nine-segmented, first segment 

 very short, hardly reaching to the fourth part of the length of the second seg- 

 ment; third to eighth segments inclusively surrounded, near the posterior mar- 

 gin, with a circle of rather densely placed brownish bristle-shaped teeth, of un- 

 equal length, appressed backwards, and shorter on the ventral than on the dorsal 

 side. Last abdominal segment small, bearing in the middle of its under surface 

 a row of similar bristle-like teeth as the other segments, and at the end with six 

 outwardly divergent comparatively strong teeth with blackish tips, arranged in 

 a hexagon of which the upper two are shorter and weaker than the remaining 

 ones. 



Hcematopota sp. — Two undetermined species of Hcematopota were 

 observed by Patton and Cragg (1913) in Madras, to oviposit, as all 

 the small tabanids observed by these authors, "on blades of grass 

 just at the edge of a shallow stream, or on the leaves of the lotus 

 plant at the edges of small ponds, but never over deep water."
