In my experience, this species is restricted entirely to grasses, 

 where the adults occur throughout the year at the base of the 

 leaves, in the region of the axils. Morgan records it also from 

 cedar, but this record is probably based on a single female which 

 had paused in flight. The life habits are thus quite different 

 from those of the species of allied genera, all of which live in more 

 or less exposed situations in t ha flowers or on the leaves of plants. 

 The ovipositor may have degenerated from disuse, the necessity 

 for the insertion of the eggs in plant tissue to secure protection 

 having disappeared with the changed habitat of the insect. In 

 this respect, as Dr. Hinds remarks, the species shows a divergence 

 toward the Tubulifera, which lay their eggs wholly externally. 

 It should be added that so great is the reduction of the ovipositor 

 that Miss Beach in describing the species was led to believe 

 her specimens all males, whereas they were really all females. 

 She directed attention in her discussion of the insect to the de- 

 pressed head, the produced front, the position of the ocelli, and 

 the elongate fourth antennal segment. 



DESCRIPTIONS OF NEW ICHNEUMONID^E AND TAXO- 



NOMIG NOTES. 



BY R. A. CUSHMAN, Bureau of Entomology . 



The present paper consists largely of descriptions of new 

 species of economic importance, together with some notes on 

 previously described species and genera and the designation of 

 a new genus. 

 Calliephialtes thurberiae n. sp. 



In color and markings this species is very like Pimpla notanda Cress., 

 which should also be referred to Calliephialtes, but in structure and in the 

 white lower surface of the scape and pedicel in the male it is more closely 

 allied to grapholithce Cress. 



Female. Length 9 mm.; ovipositor 8 mm. Face as wide as long and 

 with a short median carina below the antennae; distance from side of cly- 

 peus to eye much shorter than malar space; eyes slightly emarginate within ; 

 postocellar line sub-equal to the ocell-ocular line; occiput but weakly 

 excavated; head throughout polished and impunctate; pro- and meso- 

 thorax polished and practically impunctate; notauli distinct anteriorly, 

 the prescutum, viewed from above, subtruncate; foveolate furrow of meso- 

 pleura obsolete above position of punctiform fovea, the latter scarcely 

 impressed; carina between metapleura and propodeum not obsolete in 

 front of spiracle; propodeum polished, with scattered punctures laterally: 

 nervellus broken at about the middle and at a distinct angle; first tergitc
