 Two males, six females.

 Two females. 



It is very probable that Borelli's Deniogorgon longiponiis- is a 

 synonym of this species, as it was based apparently on no char- 

 acter than the presence of visible alar squamae. The present 

 scries contains two females which possess visible squamae, and 

 we have also seen another individual of the same sex of similar 

 character. In each case the winded type was taken with the 

 non-winged phase and we are convinced this is a condition similar 

 to that found in the genus Pmlis. The species is, however, very 

 distinct from the widely-spread ''riparia^' type; xanthopu.s, as 

 pointed out by Borelli (vide supra), differing in the sculpturing 

 of the male abdomen, in the shape of the pronotum and of the 

 forceps and of the disto-dorsal abdominal segment of the male. 

 In addition the limbs are also more slender in xanthopu.s. 



Labiidae 

 Strongylopsalis iheringi new species (Plate X, fig. 1.) 



Clearly a memljer of the present genus and more nearly allied 

 to S. boliviana (Bormans) than to cheliduroidcs (Bormans), the 

 genotype. The new form agrees with boliviana in the general 

 size, the number of antennal joints and the general form and 

 symmetry of the forceps. From boliviana, however, it differs in 

 the greatly produced linguiform process of the pygidium and in 

 having a decided tooth on the interiuil face of the male forcej^js.
