short blunt spines, the extra spines shorter than the lateral ones and near the 

 summit of the segment ; equally spaced as far from each other as from the lateral 

 spines; wings with only the basal and median nervures testaceous, the second 

 transverse cubitus whitish. Abdomen dull, finely rugulose and reticulate, some- 

 what striate near base and with three equidistant longitudinal raised lines on the 

 basal fourth. Thinly sericeous, the pubescence hiding the tegument in no place. 

 Black; anterior femora and tibia? and middle femora yellowish ferruginous; pos- 

 terior trochanters and femora ferruginous, the femoral with the apical fourth 

 black; middle and posterior tibite with the apical half blackish, the basal half 

 yellowish ferruginous ; tarsi blackish ; mandibles yellowish ferruginous, black at 

 apex.

'Chelonus egregicolor, n. sp. 



Male. — Length, 5mm. Head dull; face rugulose; cheeks closely, rather ob- 

 scurely punctured, almost appearing reticulate; clypeus shining, distinctly, 

 closely punctured with small punctures, the anterior margin smooth ; scape as in 

 texanoides, pedicellum almost as long as wide, first joint of the flagellum dis- 

 tinctly longer than the second, if anything longer than the scape, antennte six- 

 teen jointed. Thorax dull, coarsely reticulate; superior face of metanotum very 

 coarsely reticulated, with a short coarse ridge at base and a similar one on each 

 side of the middle at the apex ; separating the reticulated portion of the metano- 

 tum from the scutellum is the strongly striated postscutellum ; the lateral spines 

 blunt and diverging; posterior face of metanotum reticulated. Abdomen dullish, 

 reticulated; basal two-thirds rather distinctly longitudinally striate, basal third 

 with a short elevated ridge on each side that diverges towards the base. Seri- 

 ceous as in texanoides. Black; mandibles except apex and base, anterior femora 

 except base, middle femora except basal half ferruginous, infuscated in part; 

 tibiae and tarsi brownish testaceous on the four anterior legs, the middle tibiae 

 blackish at base, tarsi blackish at apex, middle third of posterior tibia? yellow, 

 basal and apical thirds fuscous; tarsi of posterior legs fuscous, metatarsus 

 brownish at base.

Chelonus altitudinis, n. sp. 



Female. — Length, 4 mm. Head dullish, rugulose; cheeks somewhat striate ; 

 face rather shining, reticulate; clypeus shining, minutely punctured; antennae 

 with the usual proportions, the segmentation of the basal segments of the flagel- 

 lum not distinct. Thorax dull reticulated; the mesonotum smooth and minutely 

 sculptured laterally; metathorax nearly as in the preceding species, the oblong 

 spaces not so distinct ; wings as in exogyrus, the basal, first cubital, recurrent 

 and discoidal nervures pale brown. Abdomen almost exactly as in exogyrus, the 

 basal raised lines nearly obsolete. Black ; legs partly yellowish ferruginous, base of 

 anterior femora, middle and posterior femora except apex black, basal and apical 

 fifth of posterior tibia? blackish, tarsi except part of the metatarsus blackish. 

 Sericeous like exogyrus and most other species of the genus.
