Nealgoa differs from Algoa in its more slender middle legs, 

 longer, unfurrowed malar space, eyes set close to the occipital 

 margin, long slender antennae, well developed tegulse and short 

 wings. 



Nealgoa banksti sp. nov. 



9- Length 6 mm. Bright fulvo-ferruginoiis; antennae 

 infuscated beyond the third joint; middle femora and tibia? 

 weakly infuscated apically; hind femora strongly so; hind tibiae 

 fuscous, internally at base and apex pale golden, due to a coating 

 of pale glistening pubescence; pulvilli black. Entire body 

 without distinct sculpture although microscopically punctulate; 

 surface subshining and clothed everywhere with dense, but 

 extremely minute pale hair. Palp' pale yellow, teeth of mandibles 

 black. Wings brownish, costal vein dark brown, discal veins 

 weak, pale brown, margin minutety fringed. Second and third 

 joints of antennal flagellum the longest, subequal, each five 

 times as long as thick; first joint distinctly shorter, twice as long 

 as the pedicel; apical joints of flagellum gradually shorter and 

 more slender, none less than five times as long as thick. Tarsi 

 densely pubescent beneath, each joint with a distinct spine at 

 each outer angle; longer spur of hind ti1)ia half as long as the 

 metatarsus. 



Type in the Museum of Comparative Zoology, from Sea 

 Cliff, Long Lsland, New York (Collection N. Banks). 



As has been stated above, the four genera referred to are 

 very closely related, but they form an extremely aberrant group 

 and are not readily placed in any family. In 1910, I located 

 Algoa in the Emboleminse, which is generally considered as a 

 part of the Bethylidae, and pointed out that it was in many 

 respects similar to the genera with multiarticulate antennae which 

 form the subfamily Sclerogibbinae. These resemblances are 

 mainly in the form of the head, pro- and mesothorax, thickened 

 fore legs and abdomen. Pedinomma, also placed in tlie Em- 

 boleminae by Ashmead and others (v. Brues '22 ) shows many 

 resemblances and is likewise widely distributed, although dif- 

 fering in the number of antennal joints. Recently Turner and 

 Waterston ('17) have referred Olixon to the Rhopalosomatidae
