ART. 6. STUDIES ON" LEUCOSPIDINAE C. J. WELD. 13 



Male.— Length 7.0-8.5 mm. Body black with markings similar to 

 female except reddish band on sixth abdominal segment is broader 

 and of equal width throughout, and there is sometimes a small red- 

 dish spot on median line toward apex. The abdomen is more pointed 

 posteriorly and has a smooth depressed area in the position of ovi- 

 positor in female. On hind femur there is just a trace of a basal tooth 

 j)receding the five large teeth. 



Described from 17 specimens, all but 2 of which were collected in 

 Florida. 



Type.— Cat No. 24381, U.S.N.M. Type female, allotype, three fe- 

 male and six male paratypes. 



One female and two male paratypes in collection of Academy of 

 Natural Sciences, Philadelphia; one male and one female paratypes 

 in collection of Cornell University ; one male paratype in Museum of 

 Comparative Zoology, Cambridge, Massachusetts. 



Habitat. — Type-locality, Capron, Florida, April 14, 



Allotype from Biscayne Bay (Slosson) ; paratypes from Capron, 

 Biscayne Bay, Orlando (March 18, 1908, Eussel), Miami (March 5, 

 1915), Gulfport (August, Renolds), Paradise Key (Mosier), Meta- 

 comba Key (March, 1898, Collins and Pollard), Ti\mpa, Florida; 

 and Tifton, Georgia. 



2. LEUCOSPIS TEXANA Cresson, 



This species was described from two male specimens collected in 

 Texas (Belfrage). The type is in the Academy of Natural Sciences, 

 Philadelphia, Cat. No. 1776, and has been seen by the writer. It 

 lacks antennae beyond the fourth segment. The United States Na- 

 tional Museum has the paratype. Cat. No. 1659. 



3. LEUCOSPIS METALOCA, new species. 



On account of its short ovipositor, absence of carina on pronotum 

 and numerous small teeth on under side of hind femur, this species 

 runs close to tolteca Cresson in Schletterer's key, but shows distinct 

 differences in sculpture of propodeum, character of pubescence on 

 abdomen, and in color markings. 



Female. — Length, 7.6 mm. A small iridescent species with high 

 keeled propodeum., golden pubescence toward apex of body., and ovi- 

 jjositor reaching less than half the length of abdomen. 



Body black with metallic tints of green and purple and few yel- 

 lowish markings as follows : faint spotting on scape laterally, narrow 

 transverse line near hind margin of pronotum obsolete at sides; 

 slightly broader band on hind margin of mesoscutum; indistinct 

 markings near base of femora above and under side of tibiae on front 

 and middle legs; upper and lower margins of hind femora, except 

 for a short distance at apex ; outer side of hind tibiae. Legs, except
