(xV. ichneumonea, De Geer., rr.) 



t These species are thus grouped: — 1. The extremity of the elytra 

 rounded, the deep impressed line along the seam whole and continued 

 round the extremity of the elytra so as to join the marginal line : (a) the 

 hind thighs not reaching beyond the end of the abdomen ; a, third joint 

 of the hind tarsi bilobate ; the base of the prothorax with obsolete depres- 

 sions in the corners, but without a transverse depression across the middle : 

 (*) cheeks as long as clypeus; hind corners of pronotum forming right 

 angles ; antennre thicker towards the top {L. livida) : (**) the cheeks 

 much shorter than the clypeus ; hind corners of pronotum with a short 

 pointed process, turned outwards ; antennae fihform {L. rujicornis, L. prce- 

 usta) ; /3, apex of third joint of hind tarsi emarginate ; cheeks shorter than 

 the clypeus ; hind corners of pronotum with a very short pointed process, 

 turned outwards; antennae thicker towards the tip (L. IcBvis) : (6) the 

 hind thighs reach some way beyond the apex of the abdomen ; cheeks as 

 long as clypeus ; third joint of the hind tarsi emarginate ; pronotum con- 

 stricted closely in front of the hind corners, which are furnished with a 

 short, pointed, flat process; antennae filiform (L. S-maculata). 2. The 

 points of the elytra truncated and emjvrginate ; the linear depression along 

 the seam interrupted at the points ; cheeks as long as, or longer than, cl)'- 

 peus : {a) hind corners of pronotum forming right angles, without pro- 

 cesses; third joint of hind tarsi deeply emarginate (L. virens) : (b) pro- 

 notum contracted closely in front of the hind corners, which show a short 

 blunt process; (J , antennae obsoletely dentated from 5th to 10th joint; 

 last abdominal joint bidentate ; $ > '^st joint of abdomen emarginate, and 

 third joint of hind tarsi bilobate {L. scutellata) : jS, third joint of hind 

 tarsi deeply emarginate (L. sanguinolenta, L. testacea) : (c) hind corners 

 of pronotum with long pointed processes corresponding in shape to the 

 shoulders of the elytra; third joint of hind tarsi emarginate, and pronotum 

 with a deep transverse impression in front of the base {L. aurulenta, L. 

 4-fasciata, L. armata, L. atra) ; ff, pronotum without any transverse im- 

 pression, but with a slight depression in each hind corner (L. nigra, L. 

 melanura, L. revestita, L. attenuata).
