Nineteenth annual meeting. 135 



than the third; first Joint swollen, yellow; second joint a little darker; third, except 

 the base, black. Dorsum of thorax with browish-yellow pollen, the median geminate 

 stripes separated by a shining black interval from the more yellow lateral margins. 

 Abdomen: The two basal segments yellow; the first with a transverse black spot below 

 the scutellum, the second with two oval divergent spots, and toward the posterior 

 margin, on the outer side, with a small rounded spot; third, fourth, and fifth seg- 

 ments each with four elongate spots ( those of each lateral pair of the third may be 

 coalescent in front), not reaching the hind margin. Venter with a broad median 

 and a slender lateral black stripe. Legs yellow, the knees, distal part of front tibiae, 

 and the front tarsi, blackish. First basal cell infuscated upon its basal two-thirds, 

 the second on its basal third; the ci-oss-band reaches the hind margin, leaving a small 

 hyaline space in the fifth posterior cell, the discal cell not lighter; the apical spot 

 fills out the marginal cell comijletely, and reaches into the second sub-marginal. 



Male: Antenna? a little darker, the first two joints not as long together as the 

 third, the first joint less swollen. Abdomen black, the narrow lateral margins of the 

 anterior segments yellow, extending in on the hind margin of the first segment and 

 across the hind margin of the remaining ones; the second, third, and fourth segments 

 each with three small triangular expansions on the hind margin. Front and hind 

 legs chiefly black, the middle legs chiefly, and the base of the hind tarsi, yellow. 

 Wings darker, the second basal cell infuscated, but with a subhyaline stripe along 

 the middle; discal cell with a subhyaline spot. 



Three specimens, California: The difference in the antennte and the hyaline spot 

 in the discal cell make the union of the two sexes as above described, somewhat 

 doubtful. The species is allied to C. fulvaster, but will be distinguished by the 

 lateral yellow spots on the abdominal segments, etc. 



H.^MATOPOTA. 

 H^MATOPOTA AMEKicANA Osten Sackcn. 



A specimen from California has the four posterior metatarsi with only a vestige 

 of white color at the base, but otherwise agrees very well with the description, 

 excepting that I would hardly describe the first antennal joint as "very much in- 

 crassated." The wide distribution of the species renders it probable that it is iden- 

 tical with Macquart's H. punctulata from Carolina.
