AMERICAN HYMENOPTKRA. 21U 



oblique conical sjiot below the tegula', apex of teguhe (their base fuscous), two 

 irregular transverse conical marks on the scutellum and the apices of the basal 

 five abdominal segments and the apices of the second to fourth ventral, bright 

 lemon-yellow. Tibine yellow, the apex of the tarsi dark testaceous. Wings 

 almost hyaline, smoky along the fore margin; the stigma testaceous, the nerv- 

 ures black. J. Total length 12 mm. 



Clypeus as broad as long, sparsely, distinctly punctured, the apex transverse, 

 depressed. Base of thorax not quite transverse, the apex distinctly keeled on 

 the sides, the oblique lower part with the keels stouter than on the upper part. 

 Thorax somewhat more than twice longer than wide, flat above, the parapsidal 

 furrows reaching from the base to the apex. Basal slope of first abdominal seg- 

 ment triangular, clearly separated above, aciculated ; the apex distinctly punc- 

 tured; the second is much less strongly punctured; it is distinctly longer than 

 wide and has the apex flat. Apex of postscutellum transverse.

What appears to be the i (from Berkeley) has the clypeus, lab- 

 rum and tarsi lemon-yellow, the coloration otherwise being as in 

 the 9; except that the flagellum is brownish below; its hook is 

 stout, brownish and hardly projects over the ba.«e of the joint. Cly- 

 peus not much longer than wide, more closely punctured than in 

 the 9 ; its apex has a seniicircular incision. The parapsidal furrows 

 are not so deep as in the $ .

Black; the clypeus, base of mandibles, eye incision, a longish mark, broad 

 above, gradually narrowed below, wiiere it is one-third of the width of the top, 

 a short narrow line on the upper part of the eye orbits, a line on the base of 

 thorax, a small, irregular, wider than long, mark in the centre of the mesonotuni 

 at the apex, postscutellum, a wide conical mark below the tegulse, lines on the 

 apices of all the abdominal segments and an irregular spot on the sides of the 

 second segment at the base, yellow. Legs pale yellow, the four anterior coxae, 

 trochanters and femora and the posterior entirely, black. Wings hyaline, the 

 radial cellule clouded, the stigma fuscous, the nervures black. %. Length 5 mm. 



Clypeus pyriform, clearly longer than wide, the apex with a wider than long

 sparsely punctured, the rest aciculated. Base of first abdoniinal segment trian- 

 gular, smooth ; the apex strongly but not closely i)unctured ; the second segment 

 is slightly longer than wide, weakly, sparsely punctured at the base, more
