WALSH DESCRIPTIONS OF N. AM. HYMENOPTERA. II7 



the antenna;, and a spot on the lower surface of the 1st antennal joint, are 

 all white. Except the above spot, the antennae are brown-black immacu- 

 late. 2. The thorax is more coarsely sculptured, and, except that the tegular 

 and a minute line under the front wing are white, all the white and rufous 

 markings of \scutellaris, Cress.] are absent. 5. The abdomen is more 

 coarsely punctate, elongate-oval instead of clavate, and of course more 

 elongate, the terminal joints being more opened out and the few last sub- 

 glabrous and polished. Joints 1-3 are proportioned as in \_scutellaris~\, 

 4-7 each about \ shorter than the preceding so that 7 is only k as long as 

 3, 8 small. 4. The 4 front legs differ in all the coxae and trochanters be- 

 ing milk-white immaculate, and in the knees and a basal exterior vitta on 

 all 4 tibiae and the basal £ of all 4 tarsi being whitish. In the hind legs 

 the coxae are black lightly tipped with white, the basal trochanters black 

 lightly blotched with white, the terminal ones vice versa; the femora, the 

 terminal § of the tibia and the whole of the tarsi black, the basal § of the 

 tibiae white; claws simple. 5. The stigma is black, and the radius only 

 basally rufous. Length o* .44 inch. Front wing o* -28 inch. 



One % ; $ unknown to me. Besides the tarsal claws being 

 unarmed, the total absence of the large white spot before the 

 front wing and the very different coloration of the sternum, 

 which are not, so far as I am aware, sexual characters in Ichneu- 

 monidcE, would forbid this 6* being correlated with the preceding 

 $ . On the other hand, the coloration of the face, antennae, scutel, 

 and legs, are common sexual characters here, of which many 

 examples occur in Basstis, Ichneumon, Pi7>ipla, etc. 



Lampronota amphimilSBlia, n. sp.— cT.— Differs from {scutellaris, Cress.] 

 5 only as follows : i. The white or whitish markings of the latter, whether 

 on the body or on the legs, become here yellow or are obsolete. 2. The face 

 up to the front except the lateral foveae at the tip, and the entire clypeus, 

 is pale yellow, with a triangular black spot beneath each antenna and an 

 acute black line descending from between the antennae nearly to the cly- 

 peus. The antennae are brown-black immaculate, except that there is a 

 small pale spot on the basal joint below. 3. Except the 3 pale spots un- 

 der and before the front wing, the largest one of which is hooked back- 

 wards near the tip, and except also that there is a minute pale vitta on 

 each side of the scutel, the thorax is immaculate and more coarsely sculp- 

 tured. 4. The 2 longitudinal carinas of the metathorax are distinct but 

 low, and diverge from the first § of their length, the enclosed space 

 being perfectly level and without any stria. 5. The abdominal joints are 

 proportioned as in \tegularis~\, but the anterior angle of 2 is reflexed into 

 a tubercle, and the spiracles of 1-3 project in a lateral tubercle, each less 

 so than the preceding. 6. Except the basal \ of joint 1, the terminal \ of 

 5, and the whole of 6-8, the abdomen is rufous. The venter is pale dull 

 rufous except towards the tip and at the extreme base- 7. Instead of the 

 middle coxae being rufous beneath, they are black on their interior base.
