very shallow punctures; scutellum shining and smooth, propo- 

 deum truncate, rugose, the truncation bounded by a raised line, 

 posteriorly densely minutely shagreened and without any definite 

 area. Fifth tarsal joint with well-developed lamellate denticles 

 in two rows and with series of long setae at the side, chelar claw 

 with long seta on the subbasal angle beneath. Abdomen smooth

 hind tarsi also more or less pale or brown, otherwise the legs 

 nearly wholly black. Neuration brown, stigma dark brown or 

 blackish fuscous. Head sculptured as in the female, and with 

 faint traces of feeble punctures ; antennae as long as the head and 

 thorax, the scape fully as long as the two next joints, which do 

 not differ much in length, the flagellum being submoniliform, 

 with the joints nearly similar, clothed with hairs not shorter than 

 their width; none of the joints are as wide as long. Mcsonotum 

 more shining than the head, with very feeble surface sculpture 

 and traces of hardly visible punctures, scutellum polished ; pro- 

 podeum/as in the female. Abdomen smooth and polished. Length

HAB. Tucson, Arizona ; bred from nymphs of a Jassi-'^ found 

 on a small bush (no. 2420) and probably the same species, with 

 the legs paler generally, the posterior femora brown with black 

 apices, was bred (no. 2461) and captured at Nogales. Mr. Koe- 

 liele's note states that the host and probably the parasite from 

 Xogales are the same as his Tucson specimens. The variation is 

 considerable, and the description of the male and ftniale is pri- 

 marilv based on two specimens bred from one individual of the 

 hopper. 



2. Cheloi^xmis iiiclanacrias sp. nov. 



Black, mandibles (except the teeth) whitish, antennae clear 

 testaceous on the basal joints, the four apical ones being black 

 (at least above) one or two of those preceding these generally 

 subinfuscate. Legs concolorous with the basal antennal joints, 

 even the coxae entirely pale, the tips of the tarsi and the apices 

 of the hind femora black or dark fuscous, the apical part of the 

 hind tibiae sometimes infuscate. 



Head dull, densely and minutely shagreened. the antennae with 

 the second, third and fourth joints differing very little in length, 

 the third being a little longer than the fourth, the fifth and follow- 

 ing wider than the latter, the seventh rather longer than its great- 

 est width. Pronotum somewhat transversely rugulose anteriorly ,
