HCEMATOPINOIDES. 
Nov. Gen. 
Antennae composed of three joints, terminal joint deeply excavated 
on the posterior side ; abdominal segments at lateral margins broadly 
chitinons with a strong tubercle and a semicircular plate above and be- 
low lapping over the chitinous portion of the succeeding segment.

gins of segments broadly chitinous, a strong tub-

the chitinous portion of the succeeding segment, spiracle located at middle of lateral 
margin ; median portion membranous, appearing minutely squamous. The sutures 
of the segments faintly indicated, a few long hairs scattered over the median portion 
of the dorsal surface, two hairs on each lateral tubercle, these much elongated on 
segments 6 an 7 ; the eighth with a tuft of hairs.
