HYMENOPTERA. TENTHREDINIDA. 53 
TENTHREDO* Leach. 28 sp. (Steph.) TT. nassata Linn. 
Two marginal, four submarginal cells; antenne rather long and slender ; third 

and fourth joints equal; abdomen rather long, depressed ; legs moderate ; 
clypeus scarcely notched. Pz. 65. 2. g. 
MACROPHYA DAlb. Attantusp. Steph. 9sp. T.rusticus Linn. Pz. 64. 10. 
Antenne 9-jointed ; body moderately long; posterior coxe very large; each of 
second and third submarginal cells receiving a recurrent nerve (‘T. blanda Fab. 
Pz. 65.9. T. punctum F. Pz. 26. 21.; and the species above mentioned are 
the types of Dahlbom’s three sections of the genus. ) 
PACHYPROTASIS Hartiy. Trnrurepo A. Steph. 4 sp.. T. Rape Linn. 
Antenne longer than the abdomen, slenderer than in Tenthredo; posterior coxzs 
very large. (Hartig makes this a section of Macrophya.) Schatf. Ice. 179. 1. 
ASTICTA Newm. Ent. Mag. vol. iv. 261.; v. 484. 1sp. <A. Janthe. 
Antenne short, slender, 9-jointed; second joint twice the length of the first ; 
third twice the length of the second; fourth scarcely shorter than the third; 
the remainder gradually shorter ; stigma distinct, membranous; two marginal 
and three or four submarginal cells; the second and third receiving a recurrent 
nerve. 
Obs. This description is drawn from Mr, Newman’s typical specimen, which 
he has been so kind as to lend me ; and of which the fore wings are unlike, 
the transverse nerve separating the first two submarginal cells being 
obliterated in one of them: thus the genus is closely allied to Tenthredo 
proper, rather than to Fenusa. 
DOSYTHEUS Leach. Dotrerus p. Hartig. 14sp. T. Eglanterie F. 
Antenne 9-jointed; body moderately long; two marginal and three submarginal 
cells, the first very short; third joint of antenne longer than the fourth. 
iRanz 82-01: 
DOLERUS Leach. WDotervs p. Hartig. 9sp. T. nigra Linn. Pz. 52. 11. 
Differs from Dosytheus in the third and fourth joints of antenne being of equal 
length. 
EMPHYTUS Leach., Hartig. 24sp. 7. cincta Linn. Curt. 436. 
Antenne 9-jointed; third and fourth joints of equal length; two marginal and 
three submarginal cells; the first as long as the second; hind wings with no 
middle cell. 
(ANEUGMENUS Aartig. (Sect. of Emphytus.) 1 sp. Emph. coronatus K1., St. 
Body short, oval; hind wings with two middle cells. ) 
(? HARPIPHORUS Hartig. Setanpria p. Steph.? 1 sp. Sel. scapularis St. 
(lepidus K], ? ). 
* Obs. Hartig regards this as a subgenus of the genus Tenthredo (which also ~ 
includes Selandria, Athalia, Macrophya, and Allantus, as subgenera), and divides 
it into six named sections : — 
1. Taxonus Meg., which includes the following British species: T. agilis Ki. ; 
T. nitidus Kl.; T. bicolor Ki. 
Strongylogaster H.: Br. sp. T. cingulata Lab. Curt. 692. 
Pecilostoma H.: Br. sp. T. impressa Ki., Steph. (Emphytus). 
Perineura H.: Br. sp. T. Rubi Panz., Steph. Ill. 
. Tenthredo: Br. sp. 'T. nassata Linn. ; T. Coquebertii K7.; T. dimidiata KZ. ; 
T. aucuparie K/.; T, mandibularis KZ. ; and many other species placed by 
Stephens both in Allantus and Tenthredo; and 
6. Synairema H. (T. delicatula KZ, not British.)
