EURYPKOCTUS. 321 



distinct ; spiracles circular, not distinctly ovate. Basal segment 

 slightly curved, with no discal sulcus, spiracles subcentral, petiole 

 slender, post-petiole apically dilated, with no lateral carinae ; cen- 

 tral abdominal segments not twice as broad as long ; terebra 

 straight and slightly exserted. Tarsi white-banded ; hind femora 

 not incrassate, the intermediate apically attenuate, with their 

 tibiae subsinuate. Basal nervure continuous through the median ; 

 areolet distinctly present. 



Range. Palaearctic and Nearctic Regions. 



JSTo doubt can remain that Cameron's two species of his genus 

 Fovaya are representatives of Euryproctus, since I have had an 

 opportunity of examining the types of both in Col. Nurse's 

 collection, and it is very obvious that their author was misled, 

 in following Ashmead's tables, by the subbuccate head of these 

 species, which, though transverse, is but very slightly constricted 

 posteriorly. 



The species of this genus are known to prey upon the larvae of 

 such TENTHREDINIUJE as Tenthredo, Eriocampa, &c.

 ($,M(J). 



5 . A black rlavous-iriarked species, with the abdomen centrallv 

 red, and the antennas and hind tarsi pale-banded. Head black, 

 with the sparsely and distinctly punctate clypeus, two indefinite 

 marks before it on the alutaceous face, facial orbits, the striate 

 mandibles (except apically), and the palpi, flavous ; frons and 

 vertex alutaceous. Antennas slender and almost longer than the 

 body, with the fourteenth to twenty-fourth joints entirely stra- 

 mineous ; scape with dense white pubescence beneath. Thorax 



t Cameron's table (Ann. Nat. Hist, xx, p. 21) is very faulty. Fovaya 

 annulicornis has a distinct, juxta-antennal orbital white mark, the apex and not 

 base of its second abdominal segment is red, the flagelluiu is equally black, 

 and the spiracular area equally strongly carinate internally in both species ; 

 and the four front, not hind, femora of F. annulicornis are testaceous.
