within the Mymaridse; it has Anaphine affinities. The type of the 

 species is a single tag-mounted specimen and is necessarily in bad 

 condition for adequate study. It is simply labelled " Alaphis pallipes 

 Ashm. Type. Jacksonville, Florida," and has no number in connec- 

 tion with it. 



The genus Alaptus now contains the following species which are 

 both valid and recognizable : minimus Walker ; iccryce Riley ; imma- 

 titrtis Perkins; globosicornis Girault ; ccvcilii Girault; eriococci Girault 

 and the new species— in tonsipennis — described beyond. The species 

 immaturus Perkins needs fuller description. The species fuscnliis 

 Walker, pallidicornis Foerster, fuscus Foerster and excisus West- 

 wood, in short all of the European species with the exception of the 

 type of the genus, are certainly unrecognizable at present and perhaps 

 for all time, and I have already indicated this. Finally, they may 

 have to be dropped from our lists. 



In my catalogue of this genus (Girault, 1908 a) these omissions oc- 

 curred : In regard to the species minimus Walker, I omitted to give 

 Enock's (1897) rearing of what he supposed was a male from the 

 eggs of Sfciiopsocus cruciatus (Linnaeus) and also his statement that 

 this same host contained the larv?e of the species fusculus Walker. 

 Concerning the latter I should think there would be even more doubt 

 as to its identity than implied in connection with minimus and that 

 the statements concerning both species should be taken for no more 

 than their worth. In the list of literature de Dalla Torre was in- 

 advertentlv omitted and no reference was made to Isaac (1907) under 

 the species cxcisns Westwood. 



These remarks, together with the following description of a new 

 species from the United States complete all that is now known con- 

 cerning this genus. The full descriptive notes given on the species 

 icerycc Riley should aid materially in advancing our knowledge of the- 

 generic characters and moreover to impress upon us the fact that 

 specific differences in this genus are what are ordinarily held to be 

 minor characters such as ciliation of the wings, wing shape and 

 antennal structures.
