species of the present genus have similarly long wings, I have not 

 retained the manuscript name of Brunei*, given by him to distinguish 

 it from the species of Dactylotum which have short wings. 



3. POECILOTETTIX COCCINATUS, new species. 

 (Plate XXVI, fig. 3.) 



Head brighter or duller yellow, more or less infumated, especially on 

 the lower half, but enlivened with crimson more or less distinctly (but 

 not so conspicuously) as in P. sanguineus and at somewhat similar 

 points, but especially on the fastigium, tlje sides of the labrum, the 

 clypeal suture, and the lateral carinae of the face, besides the medio- 

 dorsal stripe of the vertex; eyes of female as in P. sanguineus; antennae 

 apically acuminate, greenish plumbeous, the basal joints pale. Prono- 

 tuin most sparingly pilose, olivaceo-fuscous with shades varying from 

 olivaceous to fuscous, the latter more pronounced on the front part of 

 the metazona and the dorsum of the prozona, except an olivaceous, 

 continuous, mediodorsal stripe, more or less conspicuously marked with 

 a crimson thread; crimson also margins the lateral lobes of the meta- 

 zona and appears more or less distinctly on the upper half of the lateral 

 lobes of the prozona; the transverse sulci of the disk are only slightly 

 darker than the ground; metazona with crowded fine punctuation and 

 a slight median carina, the hind margin strongly convex, hardly angu- 

 late. Tegmina slender, far surpassing the abdomen, hyaline on more 

 than the apical half, the veins yellow; wings nearly as long as the teg- 

 mina, greenish hyaline, the veins of the upper half fuscous or greenish 

 fuscous, of the lower half and most of the cross veins glaucous. Fore 

 and middle femora luteous, clouded with fuscous; hind femora luteous, 

 the outer face infuscated and the upper area alternately pale fuscous 

 and luteous or carmine; hind tibiae and tarsi glaucous, the spines glau- 

 cous or pallid with black tips, seven to eight on the outer row in the 

 female, eight in the male. Abdomen light fuscous with dull luteous 

 areas, but no enlivennient with brighter colors; supraanal plate of 

 male triangular, elongate, the apex acute; surface with two parallel, 

 not distant, sharply elevated ridges which extend, diminishing pos- 

 teriorly, nearly or quite the length of the plate, including between them 

 a rather narrow and deep narrowing sulcus; furcula consisting of only 

 a slight thickening of the posterior edge of the last dorsal segment 

 above the two ridges of the supraanal plate; cerci not very broad at 

 extreme base, rapidly and regularly tapering in the basal third, the 

 remainder very slender, equal or barely expanded at the blunt 

 extremity; lateral margins of the subgenital plate straight on the 

 apical half, the apical tubercle not rising above their level but having 

 the same direction, conical, simple. 



Length of body, male, 20 mm., female, 30 mm.; antennae, male, 7.5 

 mm., female, 8 mm.; tegmina, male, 19 mm., female, 24.5 mm.; hind 

 femora, male, 10 mm., female, 14 mm.
