WALSH DESCRIPTIONS OF X. AM. HYMENOPTERA. 121 



Lampronota [amerieana, Cress., Trans. Am. Ent. Soc. iii. p. 164].—$. 

 — Black. Head subopaque, densely and rather coarsely punctate. Cly- 

 peus and palpi dull rufous, the clypeus polished. Mandibles piceous. 

 Antennae brown-black, \ as long as the body. Thorax subopaque, conflu- 

 ently and rather coarsely punctate; metathorax opaque, coarsely rugoso- 

 punctate, the longitudinal carina; obsolete. Abdomen elongate-ovate, 

 almost microscopically punctate, subpolished ; joint 1 slightly rugose, 

 about i\ times as long as wide, £ wider behind than before, its sides 

 straight, the usual carina; fading out at \ the way to the tip; 2 and 3 each 

 i shorter than 1, and £ longer than wide; 4 shorter than 3 by ? ; the re- 

 maining joints rapidly shortened. Basal f of 1 black, the rest of abdo- 

 men rufous. Venter pale dull rufous except the basal £ of 1 ; 6 triangu- 

 larly prolonged beyond the tip by a space nearly equal to £ the breadth 

 of the abdomen. Ovipositor as long as the body, piceous; sheaths black 

 , and of uniform width throughout. Legs black, with the front tarsi, the 

 tip of the front tibia; and sometimes the whole of them and the knees as 

 well, all dull rufous. Claws simple. Wings tinged with yellowish smoky; 

 veins black; stigma black tinged with rufous at base, and 3 times as long 

 as wide. Areolet with the peduncle § as long as the rhomb. Length $ 

 .47-.50 inch. Front wing 0. .35-. 39 inch. Ovipos. .50-.53 inch. 



Two 2 i 6* unknown to me. Distinct from all the preceding, 

 and from rnjithorax, Cress. (Cuba), by the total absence of any 

 white or yellow markings. Comes very near montana, Cress., 

 but differs by the 4 hind legs being entirely black, by the wings 

 not being fuliginous, and probably by the unusual prolongation 

 of the 6th ventral, which is not referred to in the description of 

 that species. 



Lampronota imitatrix, n. sp. — 5 — Differs only as follows from the 

 preceding: — 1. The size is \ smaller. 2. The teguhe are brownish- white. 

 3. The longitudinal carina; of the metathorax are represented by two 

 parallel stria; confluent in front and evanescent § of the way to the semi- 

 lunar carina. 4. The abdomen is distinctly but very finely punctate; joint 

 1 is twice as wide behind as before, and the spiracle projects laterally in 

 a distinct tooth, the sides being otherwise straight; 2 and 3 are each only 

 \ longer than wide, and 4 is f as long as 3. 5. Abdominal joints 5-S are 

 black both dorsally and ventraUy, joint 1 being colored as in [amerieana, 

 Cress.] 6. The 6th ventral is not unusually prolonged. 7. The oviposi- 

 tor is pale rufous, and is a little shorter than the body. 8. The legs are 

 entirely pale rufous. 9. The wings are subhyaline, the radius pale rufous, 

 and the stigma black, brownish-white at the extreme base and rufous at 

 the extreme tip. The peduncle of the areolet is scarcely h as long as the 

 rhomb. Length Q. .35 inch. Front wing $ .23 inch. Ovipos. .29 inch. 



One ? ; j\r unknown to me. Distinct from rujithorax, Cress., 

 and from all the preceding but \americana, Cress.], by the ab- 

 sence of pale markings, and well separated from [americana>
