Menibrncidae of the Biologia* described 

 as a new genus and species Gargaropsis 

 innervis wliich lie placed in Centiotinae 

 remarking that it was " one of the puz- 

 zling genera which appear to be rightly 

 placed at the end of the Centrotinae 

 and which on the other hand scarce- 

 ly appear to be true Membracids."' 

 " The present genus is very distinct 

 from any other described and does not 

 seem to have any very striking affini- 

 ties." Certainly not in Membracidae. 

 It is a typical Macropsis by description 

 and figure and from its size may be 

 distinct from either of Stal's species. 



It is rather a sad commentary on the 

 accuracy of Fowler's work in the Biol- 

 ogia on Jassidae at least, which he is 

 just beginning, that he should have de- 

 scribed as one of the Membracidae a 

 well known Jassid genus of almost 

 world wide distribution, two species of 

 which occur commonly in his own coun- 

 try. 



Mr. Baker in a recent paper on the 

 genust described six species as new to 

 North America. He was evidently not 

 aware of Osborn and Ball's description 

 of apicalis from lowaj described two 

 years before his paper, nor of Fowler's 

 species from Mex. of three years be- 

 fore, as he mentioned neither of them 

 in his distribution of the species. 



Most of his new species were based

on a very meager amount of material and 

 are of very doubtful validity when com- 

 pared with a larger series of specimens. 



His alabamensis is apicalis O. & B. 

 The white hair, dark suture, and three 

 apical dots on elytra as well as the gen- 

 italia readily distinguish this species. 

 His ritfoscutcllata {its) seems to be 

 identical with specimens from Vera 

 Cruz, Mex., the males of which fit Stal's 

 description of niissflla (founded on a 

 male) in every particular. It is a com- 

 mon Colo, species from the first foot 

 hills up to gooo ft. It varies much in 

 the amount and depth of color on scu- 

 tellum and clavus. Some specimens 

 from both Colo, and Mex. have only a 

 trace of testaceous while in others most 

 of the clavus is covered with dark 

 fuscous. 



The species he described as calijorni- 

 ai{iis) occurs very commonly here in 

 Colo. It is also variable in size and 

 color in a large series, some females be 

 ing entirely pale green while others are 

 very heavily marked with black. The 

 elytra in these specimens very rarely 

 show supernumerary veins, the notch in 

 the female segment varies from rectan- 

 gular, to rounding with a broad me- 

 dian tooth. A slight notch in this tooth 

 would complete the variation necessary 

 to form his magna {us) which was founded 

 on a single female, undoubtedly only 

 variety of his calif ornica. I fail to com- 

 prehend what he means by " Pronotum 

 without distinct supernumerary veins." 



His atra is undoubtedly only another 

 color variation of the californica male,
