 Described by the author as follows: 



Bacunculus stramineus Scudder, sp. nov. (pi. I, fig. 1). Body verj- slender, flavo- 

 testaceous, the sides of the thorax, the undersurface of the metathorax, and most of 

 the undersurface of the middle femora white or hoary, at least in the male, the 

 tibiae more or less tinged with green in the female; the terminal al)dominal seg- 

 ments are more or less hoary (male) or green (female). Head a little longer than 

 the pronotum, somewhat tumid in the female, laterally striped with white in the 

 male, in the latter with a pair of longitudinal rug.e following behind the inner mar- 

 gin of the antennal scrobes; antennae pale green (female) or testaceous, becoming 

 apically infuscated (male), very slender and shorter than the body. Body smooth, 

 the thorax with a feeble median carina. Seventh abdominal segment of male nearly 

 as long as the eighth and ninth together, the ninth slightly longer than the eighth, 

 the seventh segment not inflated, bearing beneath a bulbous body not reaching the 

 extremity of the eighth segment with a cap which a little surpasses it; ninth seg- 

 ment cylindrical, equal, truncate, bearing a pair of cerci, straight, rather stout, Imt 

 compressed, equal and apically very briefly and bluntly bifid plates, nearly as long 

 as the segment. 



Length of body, male, 50 mm., female, 42 mm.; antenna?, male, 22 mm., female, 

 26 mm.; head, male, 2.5 mm., female, 2.5 mm.; thorax, male, 23 mm., female, 

 18.5 mm.; mesothorax, male, 12.5 mm., female, 9 mm.; abdomen, male, 23.5 mm., 

 female, 22 mm.; fore femora, male, 14 mm., female, 10.5 mm.; middle femora, male, 

 11.5 mm., female, 8 mm.; hind femora, male, 14 mm., female, 10.5 mm.; width of

PSEUDOSERMYLE BANKSII, new species. 



Body very slender, testaceous, paler below. Head pale, slightly 

 longer than the pronotum and distinctly swollen anteriorly, the sides 

 marked with a longitudinal black stripe and with the usual longitudi- 

 nal carina? on top between and behind the eyes. Body smooth, with 

 scarcely a trace of a median carina; mesothorax nuich \ongvv than tlu^ 

 metathorax. Seventh segment of the abdomen slightly shorter than 

 the eighth and ninth together and considerably swollen on the posterior 

 half, and here furnished with the usual ventral appendage, which is 

 slightlv longer than the eighth segment; eighth and ninth segments 

 subequal in length, the latter the larger and equal. The cerci are as 

 long as the last abdominal segment, moderately slender, slightly com- 

 pressed, curving verv slightly downward and inward, and are apically 

 triiid, tie center branch curving inward quite abruptly and forming 

 the terminus of the main body of the cerci.
