ART. 24. NEW REARED PARASITIC HYMENOPTERA GAHAN. 15 



picion that Contarinia sorghicola and G. caudMa are the same 

 species. 



The original description of Eupelmus popa is short and based upon 

 the female sex only. Following is a more detailed description of 

 both sexes : 



The species is not a wholly typical Eupehnus. The middle tarsi 

 are swollen but the spines beneath are pale and inconspicuous; the 

 axillae are not broadly separated at base and the postmarginal vein 

 is only slightly longer than the stigmal. The abdomen is collapsed 

 and shrivelled so that one can not determine whether or not the 

 dorsal segments are emarginate. 



Female.— Length, 2 mm. Slender; head and thorax rather weakly 

 reticulately sculptured, the malar space a little more strongly so 

 than the rest of head ; liead transverse, not broader than the thorax ; 

 scrobes triangular, deep; eyes bare, not large; lateral ocelli about 

 the diameter of an ocellus from the eye margin; antennae inserted 

 slightly below the eyes, 13-jointed, clavate; scape rather short, 

 slightly compressed ; pedicel rather slender, more than twice as long 

 as broad; ring-joint about half as long as broad; funicle 7-jointed, 

 not counting the ring-joint; the first subquadrate; second distinctly 

 longer than broad; third the longest and fully one and one-half 

 times as long as broad; fourth nearly as long as the third but 

 broader; fifth and sixth subquadrate; seventh somewhat broader 

 than long; club 3-jointed, ovate, about equal in length to the three 

 preceding funicle joints ; mesoscutum deeply impressed behind, par- 

 apsidal grooves deeply impressed anteriorly, the triangular median 

 lobe short and convex; legs moderately long, middle tarsi rather 

 short; submarginal vein equal to the marginal and postmarginal 

 combined; stigmal a little shorter than the postmarginal; abdomen 

 a little longer than the head and thorax, somewhat compressed, 

 conically pointed at apex, weakly sculptured; ovipositor sheaths 

 about four-fifths as long as the abdomen. 



Head, thorax, coxae, and abdomen dorsally except at apex, metallic 

 green; apex of pedicel, ring-joint, tegulae, triangular pleural plate 

 in front of the tegulae, legs except coxae, and abdomen beneath pale 

 yellowish; antennae except as noted black, the scape more or less 

 metallic; middle femora near apex usually with a small brownish 

 spot in front, their tibiae with a narrow dark brown band near 

 base; abdomen apically above and at sides more or less brownish; 

 wing hyaline. 



Male. — Length, 1-2 mm. Sculptured like the female. Parap- 

 sidal grooves distinct, narrow, not deeply impressed; abdomen 

 shorter and narrower than the thorax. Head, thorax, and abdo- 

 men entirely metallic green; base and ventral margin of scape to 

 near apex, apex of pedicel, ring-joint, palpi, tegulae, and legs except
