This species might be considered to run to Sudylus Bnys- 

 son in Gahan's table of the genera of Opiinae (Ic. 66-67), but 

 the maxillary palpi in that genus are said to be short and 

 three- jointed. It is certainly, in my judgment, congeneric 

 with the other African species described as Hedylxs. 



Alysiinae. 

 7. Alysia lusoriae n. sp. 



Length 6 mm., wing 4.75 mm. to 5 mm. 



Rufo-testaceous, highly polished and shining; tips of mandibles, an- 

 tennae from the third joint, eyes, ocelli, last joint of from tarsi, middle 

 tarsi, sheaths of ovipositor and wing venation black or infuscaie ; 9-15 

 joints from the apex of antennae white; clypeus and mandibles, except 

 apex, and palpi pale testaceous ; wings subhyaline. 



Head broader than the thorax; maxillary palpi 6-joi;!ied, reaching 

 the apex of the front coxae ; labial palpi 4-jointed, a little longer than 

 the three basal joints of the maxillary palpi ; clypeus produced from its 

 base, almost fusiform, somewhat tectiform, the apex a little rounded ; face 

 above the clypeus a little rugose, not distinctly ridged,, hirsute, consute 

 at the sides beneath the antennae ; a consute or crenulare tr.insverse 

 furrow between the antennae ; posterior ocelli in front of a line connect- 

 ing the summit of the eyes, about four times as far from the eye mar- 

 gin and the occiput as from each other, connected by a furrow with 

 the occiput, eyes orbicular, separated in front by about four times their 

 apparent width ; genae about as wide as the eye seen from the side ; 

 antennae 33-jointed, third joint shorter than fourth, the remainder suc- 

 cessively shorter, but all longer than broad. 



Thorax broader than the abdomen; parapsidal furrows ."^trong, crenu- 

 late, converging behind and meeting before the prescutellar sulcus, antero- 

 middle portion parallel, abruptly directed outwardly in front, joining the 

 crenulate marginal furrow of the lateral lobes, median lobe strongly de- 

 clivous anteriorly, not arched transversely in front ; prescutellar sulcus 

 large, about twice as broad as long, divided in the middle by a straight 

 fine carina and laterally by some three or four irregular ones or sub- 

 reticulate; the lateral pits of the scutellum with longitudinal carinae or 

 striae; metanotum laterally crenulate projecting in a trifid costate-cari- 

 nate mass in the middle ; sides of pronotum consute ; an oblique sub- 

 vertical consute impression not joining the longitudinal sulcus on the 

 mesopleurae, the longitudinal sulcus abruptly narrowed in front and 

 more gradually behind, broad with many transverse lines or carinae ; 

 median ventral line of mesothorax crenulate ; propodeum areolate, a 

 median carina at base more or less interrupted at the beginning of the 

 declivity and continued as two carinae below, some transverse broken 

 carinae at the declivity and an irregular transverse costatc carina above 

 the insertion of the abdomen; the spiracles small and circular.
