Straliai!. and \\ aratah, I liiid that thuugh in ihu great majority of specimens the 

 second joint C)f the palpus is drawn out, the degree or length of this part varies 

 considerably, though in only three out of seventy is the extension absent, and 

 these three do not appear to be separable by any other character. Ii: my opinion 

 the two names must be regarded as referring to the one species. The clothing 

 varies considerably in different individuals, both on the thorax and abdomen, and 

 there is a good deal of difference in size, so that the name constaus was not a 

 happy choice. In most specimens the first posterior cell is widely oi)en, but in 

 some it is narrowed at the apex, and in five out of the 70 specimens examined this 

 cell is closed in the margin.

I am indebted to Air. Hill for a specimen of V. hilli Taylor, and for the kian 

 nf a series for comparison. The species is a very variable one in the coloration 

 of the abdomen and in the presence or absence of the median triangular spots, 

 but specimens in Mr. Hill's series agree exactly with specimens of S. iudistiuctKS 

 determined by Mi^^s Ricardo. Mr. flill has kindly Ncrified this l)y comparing a 

 specimen determined by Miss Ricardo with Taylor's type. Miss Ricardo's name 

 has precedence by about a month. .S" insiihiiis Ric. is a closely allied species, 

 smaller and with somewhat dift'erent antL-nnae and pal])i.
