and R. claripennis Banks from Kansas. R. chinensis is smaller than luci- 
fugus; the ocelli are larger and the post-clypeus and the tibiae are more 
greyish-yellow colored, not so light castaneous; the post-clypeus is shorter 
and the fontanelle is smaller. Chinensis has not the yellow tibiae and tarsi 
of flavipes, ocelli are nearer to the compound eyes and the pronotum is smaller 
as is the entire insect. . claripennis has lighter colored wings. 
Soldier.~Head light yellow-brown, not twice as long as wide, ratio of 
length to width 1: 0.62—1: 0.63, sides parallel; with dense long hairs, rounded 
posteriorly. Eye spots indistinct if present. Gula slender, width at center 
being about one-half the width at the front. Mandibles dark castaneous with 
a reddish tinge, ‘‘S’’ shaped, incurved at tips; at base of left mandible two 
small marginal teeth—one sharp tooth and one small, broader, blunt (double?) 
tooth; right mandible with no teeth. The basal knobs of the mandibles are 
not regarded as teeth. 
Antennae white with a yellowish tinge, with 16 segments, pubescent; 
third segment short, ring-like; fourth twice as long as third; fifth equals 
fourth; sixth longer; last segment elongate and sub-oval. 
Labrum yellow-brown, narrow, pointed at apex, where there are long hairs. 
Pronotum white with tinge of yellow, not as wide as head, nor not nearly 
twice as broad as long, emarginate both anteriorly and _ posteriorly,turned 
up anteriorly. 
Legs white, with tinge of yellow, pubescent.

Length of entire soldier: 4.9—-5.4 mm. 
Length of head with mandibles: 2.6-2.75 mm. 
Length of head without mandibles (to anterior): 1.85—1.90 mm. 
Length of left mandible: 1.5 mm. 
Length of pronotum: 0.55—-0.6 mm. 
Length of hind tibia: 0.95-1.0 mm. 
Width of head: 1.10—1.20 mm. 
Width of pronotum: 0.85 mm. 
The soldier of chinensis has a larger pronotum than that of speratus 
Kolbe, and the mandibles have slightly different marginal teeth; the soldier 
of chinensis has a longer, broader head than that of flaviceps Oshima. 
Type locality. —‘‘Suifu, Szechuen, (or Szechwan) China.”
