1911] Girault, Species of Trichogrammatilce (Hymenoptera). H7 



ific distinction in this genns as we shall see later. Neither the des- 

 cription nor the figure have reappeared in print. 



After the original description of this species was published 

 (Riley, 1871) Packard (1872) stated that Riley had proposed the 

 MS. name of Pentarthron for it (see p. ) and as we have seen 

 in the quotations just given this proposal was mentioned later by 

 both Riley and Comstock ( 1879, as Pcntarthrum and again by 

 Riley in 1881 as Pentarthron. In 1897, Aurivillius referred the 

 species to his genus Oophthora (see page ) but as has been 

 mentioned already elsewhere this genues is a true synonym of 

 Pentarthron; finally Ashmead (1904) again gave it as the type 

 of Pentarthron and he was certainly correct.. 4 Otherwise the spe- 

 cie? has been treated as of Tricho gramma Westwood with these 

 exceptions: — Dyar (1893) referred it to Cha'tostricha Haliday 

 (Chaiostieha Dyar) without explanation, including at the same 

 time minutissimum as a synonym; and de Dalla Torre (1898) 

 under the name of pretiosa treated it in the same manner that 

 Dyar did. 



Further references to it in a systematic way are too unimport- 

 ant for detailed mention, but all are sufficiently clear as given 

 in the bibliographical list preceding these remarks. As a matter 

 of fact the great majority of these references do not have any 

 bearing at • all on the taxonomy of the species but concern 

 its economy in nature as a parasite of injurious insects and also 

 its biology. It has not received serious attention from the syste- 

 matic standpoint since Packard (1883). 



Both from the standpoint of taxonomy and from that of econ- 

 omic entomology this species is an important one, in fact ttif* 



4. At the same time Ashmead also proposed Xanthoatomus as a genus 

 to be separated from Pentarthron by its slender abdomen; its type species 

 allopes was simply mentioned. I am certain that this species is none other 

 than minutum and m< si (1909) has shown it to be generically similar to 

 Oophthora; it is desirable to rid ourselves of it and for obvious reasons I 

 make it a synonym.
