SPILOCHALCIS ELACHIS, new species 



This species is closely related to S. hirtifemora (Ashmead) but 

 differs in having the head wider in comparison to the thorax, the 

 propodeum very weakly carinate, with the areas between carinae 

 reticulated rather than glabrous ; the spiracular slits of the propodeum 

 are wider dorsad than ventrad, while these openings are uniform in 

 width in Jiirtifem,ora. 



Description. — Dull yellow or orange; venter of thorax, vague 

 longitudinal stripe on mesopraescutum, and most of abdomen, light 

 brown. 



Female: 2-2.5 mm. Apex of antennal scape reaching level of 

 dorsal margin of anterior ocellus, pedicel equal to and ring segment 

 one-quarter length of segment 4, segment 5 slightly shorter than 4, 

 6 slightly longer than 5, 6 to 10 equal, 11 slightly shorter, 12 slightly 

 longer than 10, 13 as long as 11 ; scrobe cavity shallow, onlj^ ventral 

 margin carinate; interantennal projection with a minute anterior 

 carina; frons minutely reticulated laterad of scrobe cavity, scatter- 

 ingly punctured just anterior to posterior ocelli and ventrad of 

 antennal bases; frontal tentorial pits not visible; width of malar 

 space one-third height of compound eye; frontogenal suture slightly 

 curved, almost straight ; combined widths of compound eyes equal to 

 interocular space at level of antennal bases; left mandible with two 

 acute teeth, ventral one slightly larger; diameter of posterior ocellus 

 slightly less than one-half interocellar space; width of head one- 

 fourth greater than maximum dorsal width of thorax. 



Dorsum of thorax densely covered by irregular, shallow punctures, 

 pubescence short, sparse ; anterolateral angles of pronotum obscurely 

 carinate, anterior dorsal margin acarinate; parapsidal furrows dis- 

 tinct; prepectus not visible, completely hidden by anterolateral angles 

 of mesoscutum ; apex of mesoscutellum with a very narrow, mesally 

 depressed lamina; metacoxae with a few large, indistinct ventral 

 punctures, remainder of surface minutely shagreened; outer surface
