PHADROCTONUS ARGYRESTHIAE, new species. 



This species is easily distinguished from minutus Ashmead, by the 

 short ovipositor. 



Female. — Length, 4.5 mm ; length of ovipositor beyond the end of 

 the abdomen, 0.75 mm. Teeth of the mandibles equal ; clypeus trun- 

 cate; head shagreened; ocellocular line subequal with the shortest 

 diameter of the lateral ocellus; thorax shagreened in addition to 

 some scattered, poorly-defined punctures; carinae of the propodeum 

 strong; middle basal area practically obsolete because the carinae 

 parallel each other; petiolar area transversely striate; petiole and 

 postpetiole shining ; no carinae from spiracles to apex of first segment ; 

 second tergite longer than the two following, twice as wide poste- 

 riorly as basally; the spiracles beyond the middle, the small lanulae 

 slightly nearer the spiracles than the base of the segment; radius 

 obtusely angulate; second abscissa slightly more than twice as long 

 as first ; nervellus not broken. Black ; mandibles, palpi, scape, pedi- 

 cel underneath, tegulae, anterior coxae, four anterior trochanters and 

 spot on intermediate coxae beneath, yellowish white; apical margin 

 of the second and following tergites, apical sternites, fulvo-ferru- 

 ginous; legs f ulvo-ferruginous ; coxae, except where mentioned, 

 black; posterior femora slightly brownish base and apices of the 

 posterior tibiae blackish; posterior tarsi and apical joint of the inter- 

 mediate pair blackish. Wings hyaline, irridescent; venation black. 



Male. — Length, 5 mm. Except that the pale color is more yellow 

 it does not diifer essentially from the female. 



Type-locality. — Ashland, Oregon. Described from 3 females and 

 3 males recorded under Bureau of Entomology, No. Hopk. U. S. 

 125G5d^, which refers to a note stating that this species is a parasite 

 on a species of Argyresthia living on Libocedrus decurrents.

BOETHUS SCHIZOCERI (Howard). 



Eubadison schizoceri Howard, Insect Life, vol. 1, p. 44, fig. 

 Bocthus hoicardl Davis, Trans. Anier. Ent. Soc, vol. 24, 1897, p. 290. 

 Boethus daeckei Viereck, Proc. Ent. Soc. Wash., vol. 11, 1909, p. 210. 



It was unnecessary for Davis to propose a new name for this 

 species. His own reference proves that he had the material which 

 Doctor Howard figured. The specimen from which the drawing was 

 made is in the United States National Museum, and it is one of the 

 types of Boethus howardi. Boethus daechei is the male of schizoceri. 

 Hearings from the host of this species indicate that the color of the 

 fore legs may vary from brownish to yellowish.
