WALSH DESCRIPTIONS OF N. AM. HYMENOPTERA. II9 



body or the legs, become here pale yellow or are obsolete. 2. The entire 

 face, except the two foveas at the tip, and the entire clypeus, are yellow, 

 and the orbits are pale yellow up to the top of the vertex, but are inter- 

 rupted just below the ocelli by a space twice as long as they are wide. 

 Beneath each antenna is a minute black triangle, and from between the 

 antenna? there descends halfway to the clypeus a capillary black line. 3. 

 The antennas are brown-black immaculate, and have on the 1st joint be- 

 low a small, pale dull yellow spot. 4. The pale spot before the front wing 

 is prolonged in a slender, pointed line along the lower edge of the humeral 

 suture nearly to its tip, and above the humeral suture there is only a very 

 minute, elongate spot opposite the tip of the preceding. The tegulse, a 

 short line under the wing, and a narrow line on the anterior border of the 

 collare, are also pale yellow; but the rest of the thorax is black. 5. The 

 metathorax is entirely opaque. 6. The abdomen has the sides of joints 

 -2-6 exactly parallel, and the terminal joints being more opened out are 

 seen to be subpolished. Joint 1 is only twice as long as wide, and twice 

 as wide behind as before, with its sides straight. Joints 2 and 3, but espe- 

 cially 2, have each a pair of subobsolete tubercles similar to those of Ephi- 

 altes, and are each ^ shorter than 1, and ^ longer than wide, 4 shorter by 

 i than 3, 5-7 each £ as long as 3, and 8 concealed. The terminal I of 1 

 and the terminal £ of 2-4 are rufous, the rest of the abdomen black. Ven- 

 ter mostly dull pale rufous. 7. The 4 front legs are rufous, with all their 

 coxa; and trochanters pale yellow. The hind legs are rufous, their coxae 

 and basal trochanters all black, with the extreme tips whitish, and their 

 terminal trochanters rufous above and pale yellow below; claws simple. 

 8. The stigma is black with its disk dull rufous, and the peduncle of the 

 areolet is scarcely 3 S as long as the rhomb. Length o* -34 inch. Front 

 wing o* -24 inch. 



One % ; ? unknown to me. Very near the preceding, but dis- 

 tinguished at once by the nearly black abdomen and by numerous 

 other characters. The interrupted orbits separate it at once from 

 all other described N.A. species. 



Lampronota pictiventris, n. sp.—d 1 .— Differs from [scutellaris, Cress.] 

 $ only as follows: — 1. The white markings of the latter, whether on the 

 thorax or the legs, become here yellowish-white or are obsolete. 2. The 

 entire head is black, except that the clypeus all but the tip which is more 

 or less of it rufous, the palpi, and the mandibles all but their black teeth, 

 are whitish. 3. The antennae are brown-black immaculate. 4. The tegu- 

 lae and a minute spot before the front wing are whitish, but the rest of the 

 thorax is black. 5. The metathorax is entirely opaque. 6. The abdo- 

 men is regularly elongate-oval and the terminal joints are subpolished. 

 Joint 1 is only twice as long as wide, \ wider behind than before, with its 

 sides straight. Joints 2 and 3 each J shorter than 1, but are no longer 

 than wide, 4-7 are each about \ shorter than the preceding joint, and 8 

 is scarcely visible. On 2 there is a pair of pretty distinct tubercles, and a 

 subobsolete pair on 3. The extreme tip of joint 3 and the whole of 4 and 5,
