GENUS CAMPONISCUS. 21 



tured ; scutellum raised, oval, shining, cenchri small, pale. The abdo- 

 men is of the length of the head and thorax, but is narrower, the apex 

 mucronate ; saw very large, black, and largely projecting. Legs white, 

 femora lined with black above, pale fuscous at the sides ; the apex of 

 the posterior tibiae and tarsi (except the last joint) fuscous. Wings 

 hyaline, the costa and stigma pale ; the last with the apex fuscous. The 

 neuration is irregular in the only specimen yet found, but it does not 

 differ essentially from that of D. testaceipes. 

 Length, scarcely 1| lines. 



The whitish legs and half white half fuscous stigma 

 will readily separate this little species from despecta. 



It was taken in England by the Rev. T. A. Marshall ; 

 the exact locality is unknown to me. 



Genus CAMPONISCUS. 



Leptopus, Htg., Blattw., 184 (non Latr.). 

 Camponiscvs, Newman, Ent., iv, 215 (1869). 

 Leptocercus, Thorns., Hym. Sc., i, 78 (in part). 



Wings with one radial and four cubital cellules, the second and third 

 of the latter subequal, and the second receiving the two recurrent 

 nervures; transverse basal nervure received between the transverse 

 costal and the stigma and nearer the former; transverse median 

 received a little beyond the middle of cellule. Lanceolate cellule con- 

 tracted near the base. Posterior wings with two middle cellules. 

 Antennae filiform, the third joint a little shorter than the fourth. 



The mandibles are moderately stout, the apical 

 tooth long ; there is no distinct subapical tooth. The 

 palpi are long, the second joint of the maxillary is a 

 little longer than the third, which is not much shorter 

 than the fourth, the fifth is longer than the latter but 

 shorter than the sixth. The basal three joints are 

 thicker than the rest, the last is the thinnest. The 

 inner lobe of the maxilla reaches to the top of the 

 outer. The apical three joints of the labial palpi do 

 not differ much in length. The clypeus is slightly

incised ; the calcaria are shorter than half the length 

 of the metatarsus ; the claws bifid. 



From the Nemati with one radial cellule Camponiscus 

 is easily known by the contracted lanceolate cellule, 

 except from Cladius, which, however, is readily known 

 from it by the second cubital cellule receiving only one
