ART. 1 AMERICAN WASPS OF THE GENUS SCELIPHRON PORTER 19 



anterior portion of scape, first segment of filament, lower side and 

 tip of second segment, yellow to ferruginous. 



Length. — Female, 19 mm. to 23 mm. ; male, 20 mm. (one specimen). 



Habitat. — Haiti, the Bahamas, Cuba, Jamaica. 



Types. — The location of Fabricius's types is unknown. That of 

 Cresson's annulatus is in the collection of the Entomological Society 

 of Philadelphia. 



As this species seems to be the only one from Jamaica or the West 

 Indies in which the segments of the abdomen are bordered with 

 yellow, there seems to be little doubt that it was the one de- 

 scribed by Fabricius as jafjiaicensis. He does not mention the pres- 

 ence of yellow on the petiole, but that feature may have been over- 

 looked, or he may have described from specimens in which the petiole 

 was entirely black, which would have been quite possible consider- 

 ing the variation which occurs elsewhere in this genus. This speci«s 

 is somewhat similar to lucae, but with the latter species the yellow 

 borders of the abdominal segments are much wider. The two are also 

 very widely separated geogi'aphically.

Pelopoeus lucae Saussure, 1867, Reise de Novara Zool., vol. 2, pt. 1, Hymen., p. 

 30, no. 1, female, male. 



Black and yellow, posterior margins of all abdominal segments 

 with a broad band of yellow ; pubescence and hairs yellow. 



Female. — Head: Frons slightly depressed, insertion of antennae 

 slightly elevated; upper part of clypeus somewhat convex; clypeus 

 bidentate or bilobed at apex, the lobes rounded; frons except above 

 antennae and clypeus covered with a dense golden pubescence and 

 numerous erect golden hairs ; antennae slender, filiform, the segments 

 having the following relative lengths: 1/24, 2/5, 3/27, 4/24, 5/18, 

 6/15, 7/12, 8/12, 9/11, 10/10, 11/9, 12/9; scape yellow, bulb fuscous, 

 second segment yellow, third segment fuscous above, yellow below; 

 rest of antennae black, minutely sericeous ; mandibles ferruginous to 

 fuscous, sparsely hairy near base; frons above antennae, vertex, 

 genae, and occiput not or only slightly pubescent, but with numerous 

 erect golden hairs, weakly punctate. 



Thorax : Surface of prothorax weakly punctate, covered with long, 

 erect, golden hairs; dorsal surface almost completely occupied by a 

 yellow area ; sides of prothorax with another j^ellow spot. Mesono- 

 tum black, hairy, densely punctate, minutely striate; scutellum with 

 a large transverse yellow spot, longitudinally striate ; tegulae yellow ; 

 an area just below the tegulae yellow; rest of mesopleural region 

 black, except rarely a few small spots of brown; w^hole mesopleural 

 and mesosternal region hairy, punctate. Metathorax black except 

 the metanotum, which has a transverse yellow spot; upper and
