ENTOMOLOGICAL SECTION. XI 



scapnlse at base brown. The disc of scutellum is brftwn, and there is a brown spot 

 on either side of the metascutum. The petiole is very long, longer than the pos- 

 terior coxje, or twice as long as the abdomen. The abdomen is brown, excepting 

 at base and apex. The posterior femora are very large, larger than the abdomen, 

 and with a large brown blotch on the whole upper surface; the teeth are twelve, 

 minute and black; wings hyaline, veins pale brown. 



Described from one S specimen captured at large. 



CH.4L.CIS Fabricius. 



Mr. E. T. Cresson described Chalcis coloradensis from Colorado, and 

 I have recently taken a specimen in Florida. Colorado is probably its 

 extreme northern faunal limit, and it will undoubtedly prove to be a 

 parasite on a common diurnal lepidopteron. 



The following species is new, and in many of its structural characters 

 differs widely from any known species. It will probably form the type 

 of a new genus : 



4. Clialcis flavipei^ n. sp. 



'^ . — Length .14 inch. Black, coarsely, deeply punctate and pubescent; ocelli 

 shining black; eyes grayish before, brown behind. There is a broad lemon yel- 

 low band on face close to eyes and between antennae and eyes, extending from 

 near vertex to labrum, the latter yellow ; there is also another narrow lemon yel- 

 low stripe back of eyes ; the pubescence on back of head is long, white and dense. 

 Antennae is short, brown and densely pubescent; thorax immaculate, coarsely 

 punctate, wiiA the parapsidal grooves obJiterated; the scutellum is broad, convex, 

 coarsely punctate, and the scapuloe are not separated from, it by grooves ; the meta- 

 thorax is povrect, coarsely, deeply reticulate and bidentate at tip ; the abdomen is 

 small, black, pointed, ovate, with a very short petiole, covered with whitish pu- 

 bescence ancf ftt/bueo/ate a< 6ase. Wings fusco-hyaline; tegulse yellow. Legs four, 

 anterior pair lemon yellow, posterior pair black, with a large bright lemon yellow 

 spot on femora above and along the edge beneath ; femoral teeth numerous, small 

 (about twenty-two) ; tibiae very greatly curved, with a yellow spot at tip. 



Described from one specimen captured at large. This species is mark- 

 edly different from any species known to me, and is very easily recognized.

 THORACANTHA Latreille. 



5. Thoracaiitlia floridana Ashmead. 



In " Entomologica Americana" for August, page 1)5, I gave a short 

 account of the discovery of this interesting Chalcis, the first of the genus 

 discovered on the North American Continent. 



The description was made from one male specimen taken while feeding 

 on the flowers of the gall berry Ilex glaler. Since then I have taken 

 twenty-two specimens : four males and eighteen females, and the female 

 differs in many respects from the male. I give here descriptions of both 

 sexes.
