HYMENOPTEROUS PAKASITES. 1881 



Genus EXOCHILUM Wesmael. 



A)5ical margin of clypeus ti-uucate. Spiracles of metatliorax oval. Cubito-ciiscoldal 

 cell receiving but one recurrent uervure; marginal cell lanceolate; raedian and subme- 

 dian cells not confluent, third discoidal present, not narrowed at base; cubito-discoidal 

 cell receiving recurrent nervure in middle. Posterior femora unarmed ; tarsal claws 

 not pectinate ; posterior tarsi with first joint about twice as long as second. Abdo- 

 men petiolate. 



Exochilum mundum (Say). 



3Iale. — Body black; head with the front, uasus and anterior orbits greenish-yellow; 

 antennae fulvous yellow; three or four basal joints above black; the first joint beneath 

 greenish yellow ; trunk with rather dense, short hairs; wings purple black; abdomen 

 much compressed ; basal joint cylindrical; second segment as long as the first or a 

 little longer, compressed towards the tip ; anterior pair of feet yellowish before ; inter- 

 mediate pair with a line before and base of tibiae yellowish ; posterior pair with the 

 tibiae, excepting the tip, and the tarsi, excepting the terminal joint, fulvous-yellow. 

 Length, 20-25 mm. (After Say.) 



Mr. Aliindt lias bred this sjiecies from Vanessa cardui and Iphiclides 

 ajax. The single specimen which he sent on and from which the species 

 has been determined agrees with this description except that the posterior 

 tibiae are black and the tarsi are dark gray. 



Genus ANOINIALON Gravenhorst. 



Head buccate, or subbuccate ; front with the median projection near the base of the 

 antennae present or wanting, face more or less narrow. Clypeus indistinctly dis- 

 tinguishable, apex acutely augulate or apiculate. Antennae longer than the body, equal 

 to it in length, or shorter. Metathorax punctate, often longitudinally sulcate (broadly, 

 but not deeply). Abdomen compressed, joint 1 sublinear; terebra shortly exserted, 

 valves towards apex usually dilated ; legs slender, or the posterior are rather strong ; 

 posterior tarsi either incrassate or simple, linear, first joint about twice as long as 

 second. (After Ilolmgren.) 



The cubito-discoidal cell receives but one recurrent nervure, and this be- 

 fore the middle ; the marginal cell is lanceolate ; the third discoidal cell is 

 present and is narrowed at base. 



Anomalon pseudargioli sp. nov. 



Female. — General color black and rufous. Face yellow, cheeks behind eyes rufous,'ver- 

 tex and occiput black with the usual yellow spots each side of ocelli ; antennal scape 

 yellow below, black above, pedicel and joint 1 of funicle black, rest of funicle rufous. 

 Thorax black above and below, the outlines of the mesoscntum defined by an irregular, 

 rufous band, which fails before and behind ; mesoscutellum with its anterior half rufous ; 

 metiinotum with a rufous band each side; front and middle legs yellow, hind coxae, 

 femora and tibiae bl.ack with a rufous spot on coxae, and the femora with a varying 

 amount of same color; wings perfectly hyaline, veins dark brown. First and second 

 abdominal joints black, slightly rufous below; remaining joints rufous, with a dark 

 shade along dorsal line, extending down more on the sides of joints 5 and 6, than on 

 3 and 4. Length, 13 mm. ; expanse, 18 mm. 



Described from four female specimens. Three were sent me by ilr. W. 

 H. Edwards, who reared them in July from pupae of Cyaniris pseudar-
