Tegul« fulvous ; wing-veins yellow, ciliaie, stigmnl vein scarcely iwo- 

 thirds the length of marginal or poslmarginal ; legs yill >w, excepting coxe 

 and last tarsal joint outwardly, which are blick, the femora, libice and 

 tarsi about equal in length for each pair, the fore legs short in proportion 

 with others. 



Dissection of the mandibles of the paratype has shown each one to 

 have four denticles, colour ferruginous with front edges darker. 



Ikfore attempting the above descripiion, eflbrls were niade to obtain 

 a series of specimens representing both sexes, but all the other specimens 

 obtained failed to agree with my first species. The additional specimens 

 were net secured until the season of 1909, when a quantity of cracked 

 corn and oats infested primarily by C(i/ant/ra oryza was ohu'wed Ju\y 26, 

 from the same grain house at IMano, Texas, where my first examples had 

 been taken. This mixed grain had been gathered from scatterings on the 

 floor, under the shelling and cleaning machinery, where it had lain for 

 probably a month before being sacked and set aside for .«;ale as chicken 

 feed. The infested grain was placed in breeding crocks at Dallas, Texas, 

 and adult parasites appeared within four days, further emergences occurring 

 August 6, 7 and 9, September 11, October 16 and 18, November 23. 

 December 16, and again on April 5, igio, and at various times since. 

 Although I had collected weevily grain from other sources in the hope of 

 rearing this or the first species, only one female had been thus secured, 

 and this specimen matured October 3, 1908, from an ear of corn infested 

 by Ca/iindra oryzie, which had been collected by myself ten days 

 previously in a field near Shreveport, La. The species agreed with those 

 of my second collection from Piano, Texas, and the record is important 

 for proof of the occurrence of the parasite in fields where the host abounds, 

 though, as might be expected, stored grain when infested by weevils 

 naturally becomes a place of concentiation of the enemy as with the host. 



At the time my specimens were being studied, still other examples, 

 comj>rising five females and one male reared from rice [irimarily infested 

 by Ca/iitiiira oryz(e, which material was obttined by Mr. D. I.. Van Dine 

 in a rice mill at Welsh, La., August 2, 1909, were discovered to be 

 identically the same parasite. The species is consequently named in 

 honour of .Mr. I ). L. \'an Dine, who furthermore submitted still other 

 identical specimens which he had collected in similarly infested rice, and 

 also on windows in rice mills at Kl Campo, Texas, June 22, and at I.^ke 

 Arthur, La., July 29. His records add materially to a knowledge of the 

 importance of the pirasiie and its distribution. These specimens are
