GENUS NEOFHYLAX Ashmead. 



This genus belongs to the Agathinse as defined by both Ash- 

 mead and Szepligeti. In Szepligeti's table to the genera of tho 

 Agathinse it runs to the genus Megagathis Kriechbaumer but 

 differs from the descriptioa of that genus in having the de- 

 pression above the antennae with a margining carina and in 

 having the second segment without any sutures. 



Neophylax snyderi Ashmead. Female: Length 7 mm. Ferruginous; 

 antenna 1 , extreme apices of the posterior tibia? and the posterior tarsi, 

 black; wings hyaline, slightly dusky, venation yellowish; costa and stigma 

 black. Prescutum denned by foveolate furrows; depression between tho 

 scutum and the scutellum with three longitudinal ruga?; the dorsal and 

 posterior aspects of the propodeum separated by a sharp carina, the dor- 

 sal aspect with four longitudinal carina? which define three rectangular 

 areas, the median one narrower than the lateral ones, the posterior aspect 

 with five rectangular areas the median one slightly broader, dorsally; ab- 

 domen shining, second tergite hearly as long as the first. 



Luebo, Congo. Described from one female collected by T. W. Snyder. 



Type: Cat. No. 14162, IT. S. N. M. 



Macrocentrus aegeriae, new species. Of the described species th is is 

 more nearly allied to mellipes Provancher, but may be distinguished from 

 that species by the sculpture of the prescutum. 



Female: Length 8 mm.; length of the ovipositor 8.75 mm.; length of 

 the antenna 9.5 mm. Anterior margin of the clypeus broadly, gently, 

 arcuately emarginate; head belosv the antenna? shining, with sparse, widely 

 separated punctures which become closer in the median area, above the 

 antenna?; posterior orbits shining, practically impunctate, except for 

 the setigerous punctures; postocellar line about one-sixth shorter than 

 the ocellocular line; scutum and prescutum shining, the scutum medially 

 with a few large punctures; notauli well defined, foveolate, reticulate where 

 they meet; scutellum shining, with a few distinct setigerous punctures; 

 depressed area between the scutum and scutellum with eleven strong 

 ruga?; propodeum transversely irregularly striate, anteriorly the striations 

 are finer and there is a tendency towards reticulation; mesepisternum 

 shining with uniform, widely separated distinct punctures; first and second 

 tergites with longitudinal striae; on the first the stria; form an elliptical- 

 shaped median area; the third and following tergites practically impunc- 

 tate; second abscissa of the radius but little shorter than the first trans- 

 verse cubitus; nervulus post-furcal by half its length. Black; palpi and 

 tegula? brownish; mcsosternum, lower part of the mesepisternum, spot, 

 on the mesepisternum and legs except the posterior tibia? and tarsi, rufous; 

 the apices of the four anterior legs paler; the posterior tibia? and tarsi 

 brownish black; a narrow pallid band at the base of tffe tibiae; wings hyaline, 

 iridescent, venation brownish.
