cojca, and a broader band running- upward from the base of the hind 

 coxa about half way to the stigma; the rest of the pleural surfaces 

 ])lack sericeous, with quite long, whitish hairs; petiole shorter than 

 the hind coxa, straight, black, well clothed with short, and some longer, 

 white hairs. 



Abdomen. — Rather short, stout, ovate, more pointed behind than in 

 front, black above; anterior plates sericeous, with a few scattered, 

 rather coarse punctures on all the plates; the last three plates with 

 short to long, black hairs; last plate rounded acuminate behind; beneath 

 black, somewhat glistening, with scattered, rather coarse punctures 

 and black hairs, most coarse and a])undant posteriorly; the terminal 

 plate rounded acuminate behind. 



Wings. — Hyaline, slightly fuliginous along the veins .and outer half; 

 tirst transverse cubital vein of the fore wing curving into the second 

 cubital cell; transverse median vein of the hind wing leaving the 

 median at a right angle with the latter, but curving somewhat, almost 

 at once, so that as a whole the angle between the two veins is less than 

 a right angle; discoidal vein nearly but not quite interstitial; cubital 

 vein well developed beyond the transverse cubital vein; teguhe black. 



Ze(/s. — Black; anterior coxa3 sericeous, almost pubescent outside, 

 and with numerous long, gray hairs; posterior coxi« slightly pubescent 

 behind; the legs as a whole strongly sericeous; hind legs with a faint 

 reddish-brown tinge; fore metatarsus Avith ten comb teeth about half 

 as long as the metatarsus; diameter of the hind tibia gradually increas- 

 ing outward, but with a slight additional increase near the tip; hind 

 tibial comb coarsely fringed, almost with spines rather than hairs; 

 posterior face of the hind tibia strongly brown sericeous; claws two- 

 toothed, ])lack. 



Zengt/i. — Female, 23 mm. 



This interesting insect seems to be different from any of the other 

 species of Clilorlon which 1 have seen. If not, it is certainl}^ an aber- 

 rant. Its general appearance is such that I regard Cresson's sugges- 

 tion that it may be the female of C. chicJilniecum as not unlikely to be 

 correct. Thus far Cuba is the only locality known for it.

I have seen no specimens of this species in an}" of the collections 

 which have come to me, accordingly I give here a translation of Kohl's 

 description, making certain changes (he counts the pedicel as the first 

 segment of the filament) of names, in order that it may agree with the 

 other descriptions in this paper. This will also include Cameron's 

 original description as Kohl included that in his. I have omitted 

 KohFs Latin diaernosis.
