cell, and the first transverse cubital vein crooked, projecting into the 

 first cubitul cell posteriori}^ and into the second cubital cell near the 

 middle; hind wing with the transverse median vein almost straight, 

 making more than a right angle with the median vein; the discoidal 

 vein nearl}' interstitial; the cubital vein only a faint trace for a short 

 distance beyond the transverse cubital, which joins the former at quite 

 a sharp angle; teguhe brownish-black sericeous, with a pubescent spot 

 in the middle. 



Legs. — Coxa% trochanters, part of femora, tips, inner edges and 

 teeth of the claws black; the rest pale ferruginous; the spines of the 

 same color, and the hairs everywhere yellow; legs everj^where more 

 or less pale sericeous; fore coxte with a pu})escent spot in front; fore 

 femora nearly all black; middle pair the same; hind pair about half 

 black; fore metatarsi with eleven (sometimes ten) comb teeth, all short, 

 the first one shortest, and wnth no alternating short spines; inner con- 

 tour of the hind ti))ia sharply bent, suddenly enlarging markedly near 

 the outer end; the hinder face of this segment strongly, coarsely, dark 

 golden sericeous; pulvilli blackish. (Plate VI, fig. 3.) 



Male. — Differs as follows: Clypeus scjuarely truncate in front; 

 mesosternum pubescent; a pubescent band extends from the middle 

 coxa? to the spot behind the prothoracic lobe; middle and hind coxa3 

 more or less pubescent; a pul)escent spot is present on the metapleural 

 lobe; the l)lack area at the side of the median segment is nearly' con- 

 cealed by the thickness of the hairs there and the extension of pubes- 

 cence across; middle femora sometimes partly pubescent; last dorsal 

 abdominal plate rounded behind, with a rather broad notch in the 

 middle; the ))late nearly as l>road as the preceding one; l)eneath, the 

 seventh plate is deeply and sharply excavated behind in the middle, 

 and with a slight median ridge on its posterior half; with a thick 

 tuft of rather short, ferruginous hairs on the posterior coiners and 

 more or less shorter hairs on the posterior margin; the terminal plate 

 is narrow, bluntly acuminate behind and with a cential depression; 

 the surface of the last two dorsal a))d()niinal plates is coarsely brown 

 sericeous. 



Leiujfh. — Females, 25-30 nun.; males, 25-28 mm. 



This beautiful species has thus far been reported only from Cuba. 



The identity of Guerin's Splwx lanieril does not seem to have been 

 settled with certainty, and 1 can not learn the whereabouts of the type. 

 Kohl regards it as a synonym of ChJorhm irhneuinoveuin Linnjvus, 

 though Guerin writes: " 11 ne faut pas confondre cette espece avec le 

 Chlorion ickneumoneuin de Fab., ou son Sphex (nandenta.'" Speci- 

 m<Mis of C cuhensl.'i in the collection of the American Entomological 

 Societ}' are labled Jaiuerl! in Cresson's handwriting, showing his opin- 

 ion on the subject, andCiuerin's description agrees quite well with this 

 insect. In any case KohFs name can not hold, being preoccupied.
