No. 2317. FIVE TRIBES OF ICHNEUMONINAE—ROHWER, 453 



placed close to the base, that is, about one-fourth the length of the 

 tergite ; ovipositor usually as long as the body. 



For the only species known the sculpture of the head, thorax, and 

 abdomen offer the specific characters. 



TABLE TO THE SPECIES. 



This table is based on females only, 



1. Median carinae of propodeiun obliterated; base of second tergite sparsely 



punctured buprestivorus Rohwer. 



Median carinae of propodeiim well developed; base of second tergite striate 2. 



2. Vertex and posterior orbits with large, distinct, separate punctiu-es; second tergite 



with fine striae which cover about one-fifth of the segment, the rest of the 

 tergite polished; third and following tergites without sculpture; ovipositor 



longer than the body tibialis (Provancher). 



Vertex and posterior orbits practically im punctate; second tergite nearly com- 

 pletely striate; third and fourth tergites finely transversely aciculate; ovi- 

 positor as long as the body foutsi Rohwer. 



APLOMERUS BUPRESTIVORUS, new species. 



This species differs from the others assigned to the genus in having 

 the median carinae of the propodeum obliterated and in this character 

 does not agree with the genus as defined by Ashmead. It also differs 

 from the others in the sculpture of the abdomen and nonfoveolate 

 notauli. 



Female. — Length 10 mm. ; length of the ovipositor 8 mm. Anterior 

 margin of the clypeus triangular in outline; middle of the face closely 

 punctured, the sides shining with a few separated punctures; front, 

 vertex, and orbits shining and with a few scattered punctures; a U- 

 shaped fovea in front of the anterior ocellus ; the dorsal aspect of pro- 

 notum irregularly striato-punctate; scutum and prescutum polished 

 with a few scattered punctures ; posterior part of prescutum irregularly 

 striate; notauli not foveolate; suture in front of the scutellum foveo- 

 late; scutellum polished, with a few scattered punctures; propodeum 

 irregularly rugoso-punctate; transverse apical carina strong; first ter- 

 gite striato-punctate basally, the extreme apex without sculpture; 

 basal middle of the second tergite with separate, poorly defined punc- 

 tm'es, the remaining part of the second and all of the remaining tergite, 

 polished. Black ; legs below coxae (except that the femora are brown- 

 ish) and abdomen beyond the fu-st tergite rufous, wings brownish; 

 venation dark brown; nervulus slightly antef ureal. 



In the paratype the second and third tergites are brownish and the 

 femora nearly black; antennae slightly longer than the abdomen. 



Type locality. — Ashland, Oregon. Described from two females 

 recorded under Bureau of Entomology number Hopk. U. S. 12020^. 

 Material collected by G. Hofer as cocoons in larval galleries of some 

 Buprestid in Mountain Mahogany (Cercocarpus parmfolius) and reared 

 at Falls Church, Virginia, by Wm. Middleton.
