pedicellate; 8 fusiform. Mouth cone somewhat wider than long, apex 
broadly rounded; tip of labrum just attaining tip of labium. 
Prothorax about three-fifths as long as width of head, and (includ- 
ing coxe) about three times as wide as long; usual spines all present, the 
two pairs near the posterior angles much the longest; anterior mar- 
ginals moderately long. Pterothorax about 1.4 times as wide as long, 
somewhat broader than prothorax; sides nearly straight, slightly converg- 
ing posteriorly ; anterior corners scarcely projecting beyond the general 
outline. Wings present.* Legs nearly concolorous with -the body; 
anterior tarsi armed with a stout tooth. Abdomen moderately stout, 
about as broad as pterothorax, widest at about segment 3, from which 
it tapers evenly to segment 6, and then rather abruptly to base of tube. 
Tube four-sevenths as long as head, widest at base, constricted just 
before apex; intermediate portion parallel-sided, exactly three-fourths 
the diameter of base; surface not spinose.

Genus IpoLotHrips Haliday, 1852. 
Idolothrips flavipes sp. nov. (Fig. 9). 
Female—Length about 3.1 mm. Color of body coal black; all 
tibia and tarsi, and at least the basal portion of antennal segments 3 to 
6, bright yellow. 
Head very slightly more than twice as long as wide, narrower just be- 
hind eyes and at base, widest across eyes; finely striated and set with 
several stout spines; vertex conical, produced, apex overhanging inser- 
tion of antenne; anterior portion of head provided with a pair of prom1- 
nent bristles in addition to the postocular, situated on either side of the 
prolonged vertex. Eyes large, finely faceted, prominent, bulging. 
Ocelli small, their diameter about equal to that of facets of eyes; anterior 
ocellus occupying extreme vertex; posterior ocelli slightly in front of 
centers of eyes, and slightly removed from their inner margins. An- 
tenne eight-segmented, slender, about 1.4 times as long as head; seg- 
*The only specimen which I have of this species has been cleared in potassium 
hydroxide, and the wings, as a consequence, are unfit for study.
