(POLYCUSTUS FRONTALIS Ashmead MS.)=EXOCHUS MANDIBULARIS Cusliman. new 



species. 

 (POLYSPHINCTA ALBOCOXALIS Ashmead MS.)=COLPOMERIA KINCADII (Ashmead). 



There are two specimens from Mount Washington. These are part 

 of the material studied in connection with my revision of the tribe 

 PoWsphinctini,

(POLYSPHINCTA ERYTHROPLEURA Ashmead MS.)=NELIOPISTHUS NIGRIDORSUM 

 Cushman. 



There were apparently two specimens of this species, since it ap- 

 pears in two of the lists, but only one has been found. This is the type 

 of nigridorsum, and is probably the 1896 specimen. The 1902 speci- 

 men was returned to Mrs. Slosson.

PROTARCHOIDES, new genus. 



Closely related to Protarchus Foerster, from which it differs prin- 

 cipally as follows: Head and thorax more finely punctate, the face 

 densely so; frons very shallowly concave, without tubercles later- 

 ally: ocelli smaller, the space between barely impressed; temph\s 

 strongly convex; notauli distinct but not especially deep anteriorly, 

 becoming obsolete far before middle ; second abscissa of radius nearly 

 straight ; hind tibia at apex and the tarsus strongly compre'i^sed, last 

 tarsal joint not nearly twice as long as fourth and much shorter than 

 third ; inner calcarium not nearly half as long as basitarsus. 



Type. — Protarchoides longipes Cushman, new species.
