segment rounded at base and more closely punctured than the follow- 

 ing segments, the apical margin slightly contracted ; third segment 

 with a large, transverse, yellow macula on each side, and the apex of 

 the fourth segment is narrowly margined with yellowish ; in one speci- 

 men the spots on the third segment are very large, while the two basal 

 segments have a small, obsolete, luteous stain on each side at base, and 

 the fourth segment has an angular yellow mark on each side ; the base 

 of the third, fourth and fifth segments are sometimes more or less 

 blackish; the apical segment is armed at tip with three long acute 

 spines, the central one the longest; ventral segments ferruginous, with 

 their base more or less blackish. Length 6 — 6| lines ; expanse of 

 wings 11 — 11] lines. 



Two specimens. This species has some resemblance to S. dubia 

 Say, in the markings of the third abdominal segment, but is otherwise 

 very distinct. 



3. Scolia amoena. n. sp. 



Black; orbits, two spots on prothorax, postscutellum, two large marks on 

 third segment of abdomen, a broad band on the fourth and a narrow line on 

 the fifth, yellow; most of legs, sides of first and second abdominal segments, 

 and most of the venter dull rufous; wings subhyaline, the costa fuscous.

 fous at base, antennae as long as the head and thorax, entirely dull

 and a transverse line on the postscutellum, yellowish ; metathorax im- 

 maculate, very abrupt behind and concave; teguke piceous. Wings

 bescence; all the femora more or less rufous. Abdomen robust, black, 

 sparsely punctured, shining, somewhat iridescent; sides of the first 

 and second dorsal segments and the whole of the second ventral, rufous;

4. Scolia regina, n. sp.
