HYMENOPTERA. 



PHILOPONITES, new genus (Philanthidae). 



Allied to PMIoponus Kohl, but differing l>y the less produced, more 

 broadly truncate marginal cell, the second submarginal extremely 

 broad below, the first recurrent nervure curved and bent backward 

 above, and the oblique trans verso-median. The first recurrent nerv- 

 ure reaches the second submarginal cell before the end of the first 

 third; the second recurrent reaches the third submarginal no great 

 distance before the middle. Tlie second submarginal is greatly nar- 

 rowed above, and the third transversocubital has a double curve. 

 There is a rather close resemblance to the American Miocene genus 

 Propliilanthus Cockerell, but there are important differences in detail, 

 e. g., in PropMlanthus the marginal cell is nearly as in PMIoponus, 

 and the third submarginal receives the second recurrent nervure near 

 the base.

PHILOPONITES CLARUS, new species. 

 Plate 64, fig. 2. 



Anterior wing about 6.3 mm. long, hyaline, with brown nervures, 

 and large dark brown stigma. The following measurements are in ju: 

 Breadth (depth) of stigma, about 240; greatest breadth (depth) of 

 marginal cell, 480; marginal on second submarginal, 320; marginal 

 on third submarginal, 720; lower side of marginal beyond third sub- 

 marginal, 320; second submarginal on first discoidal, 320; second sub- 

 marginal on third discoidal, 800; third submarginal on third discoidal, 

 448; lower side of third submarginal beyond third discoidal, 592; 

 second discoidal cell on median, 80. 



Oligocene at Gurnet Bay (Brodie). Lacoe Coll. 7620. 



The names PTiiloponus and Acolpus applied (Kohl, 1889; Vachal, 

 1893) to the modern genus are both preoccupied (PMIoponus Thorell, 

 1887; Acolpus Jayne, 1883). Kohl suggests that perhaps the name 

 Pseudoscolia Radoszkowski may be available. 



Holotype.— Cat. No. 61409, U.S.N.M. 



ANEURHYNCHUS CONSERVATUS, new species (Diapriidae). 



Plate 64, fig. 1. 



Male. — Length about 2.5 mm.; anterior wings about 2.5 mm. long, 

 broad and ample, with the stigma about equally distant from base 

 and apex; hind wings relatively short, nanow, 1120 ju long and about 

 192 broad, the margin ciliate; antennae long, the three joints which 

 can bo seen (a considerable distance from base) much longer than 

 wide; head rather small, in lateral profile very broad oval; hind 

 ooxae very stout, about 225 fx long and 160 broad; periole of abdo-
