466 HTMENOPTERA. 



Subfam. PABNOPINjE. 



A very distinct group, readily known by the elongated trophi. Two North- American 

 species have been described. 



PARNOPES. 



Parnopes, Fabricius, Syst. Piez. p. 177 (1804). 



l. Parnopes Mvicornis. (Tab. XX. figg. 1, la.) 



Viridis, rugoso-punctata, flagello antennarum, tegulia, postscutello, geniculis, femoribus, tibiis, tarsia abdo- 

 miniaque apice, fulvis ; alia hyalinia, apice fere fumatis. > 



Long. 9 millim. 



Hab. Mexico, Presidio (Forrer). 



Face densely covered with white hair, the hair concealing the sculpture ; vertex 

 strongly punctured; clypeus dull fulvous ; mandibles black at the base and apex, the 

 middle part fulvous. Thorax much more strongly punctured than the head; the 

 punctuation on the centre of the mesonotum less strong than on the pronotum and 

 scutellum; mesopleurae densely covered with white hair; postscutellum deeply and 

 roundly incised at the apex ; the sides almost truncated ; the sides of the scutellum and 

 postscutellum densely pilose. Abdomen strongly punctured (but less so than the 

 thorax) ; the segments depressed at the apex, this part being fulvous and covered with 

 white pile (the pile longer and denser at the sides) ; apical segment with an elongated, 

 deep wide fovea on either side, the fovea? being separated by a partition which is 

 depressed in the centre, and does not reach the level of the part of the segment behind 

 it ; the extreme apex spinose, the centre bearing two spines which are longer and 

 thicker than the others ; the ventral surface scarcely punctured, dull fulvous, darkest 

 in the centre. Legs covered with a white pile. The head and thorax have a coppery 

 tint, and the abdomen a bluish tinge. The parapsidal furrows are scarcely indicated ; 

 the pronotum has a depression in the middle, especially noticeable in front. 



P. edwardsii, Cresson, from California and Vancouver, has the apex of the post- 

 scutellum entire; and P. chrysoprasina, Smith, from North Carolina, has the apex of 

 the postscutellum incised. The latter differs from P. fulvicornis in having the post- 

 scutellum and the abdomen green, and the wings fulvo-hyaline ; and no mention is 

 made in the description of the white pubescence so characteristic of P. fulvicornis.
