mesorufus and C. weemsi in southern Florida seems to confirm the 
specific distinctness of these close congeners. 
A full description of C. mesorufus appears in my survey of 
mesostenine Ichneumonidae in the Lower Rio Grande Valley (Por- 
ter 1977: 33-5). My Texas specimen was collected on 2 April 1975 at 
the McAllen Botanical Garden, where I swept it from thorny bushes 
at a site “dominated by Prosopis juliflora ” with Condalia obovata, 
Celtis pallida, Ehretia anaqua, and Baccharis neglecta in the small 
tree and shrub stratum.

(Fig. 3) 
Chromocryptus planosae vandykei Townes, 1962. Bull. U.S. Natl. Mus. 216 ( 3 ): 258. 
Holotype $: “Havilah”, Fresno, California (San Francisco). 
Chromocryptus vandykei Carlson, 1979. Catalog of Hymenoptera in America north 
of Mexico 1 : 458. 
This is the only Chromocryptus of which I have not personally 
examined material. It remains known only from the unique holo- 
type collected at Havilah, Fresno, County, California on 16 May 
1930 by E. C. Van Dyke. It may be identified by reference to the 
foregoing key and to Townes’ original treatment [1962 (3): 258-9].

(Figs. 1, 13) 
Female. Color: antenna black with some brown staining, 
especially below toward apex, and with a white band above on flagel- 
lomeres 6-9; head and mesosoma black with white markings as 
follows: orbital ring rather broadly, except for a brief interruption 
at bottom of eye and sometimes another short break above at level 
of front ocellus; transverse blotch on clypeus; large blotch on basal 
0.5 of mandible; anterior margin of pronotum broadly over about 
median 0.8; white band on humeral margin of pronotum, which 
apicad becomes narrower, sometimes irregular, and sometimes suf- 
fused with brown; most of tegula; most of subalarum; about basal 
0.4-0. 3 of scutellum; and sometimes a spot in lower hind corner of 
mesopleuron; gastric tergites 1-3 varying from mostly red with 
much blackish staining laterad on 2 and 3 to mostly black with 
irregular reddish suffusion, the 2nd tergite sometimes with a small
