92 Dr. A. S. Packard, Jr's Revision of the 



terrupted ruesially, tubercle yellow; a yellow line on the nieta-scutel- 

 lum only, present in my specimens. The rnetathorax is roughened 

 especially on the sides which are traversed by coarse thin parallel 

 folds, no distinct enclosure deniarked; mesial furrow narrow, and 

 terminates just below the bend of the scutelluni. Wings a little 

 clouded and irridescent, tegulae darker than usual, coxae of fore legs 

 black; femora black at base and externally, but within and towards 

 the tip yellow testaceous; tibiae long and slender, simple, not dilated, 

 yellow testaceous within, tarsi pale yellow, dark at tips of joints ; mid- 

 dle femora black, yellow at tips, tibiae yellow, black ovate spot within ; 

 first tarsal joint no longer than the two succeeding ones together, the 

 terminal joint being unusually long, thus greatly differing from 9 > 

 pale but dark at tips : hind femora long and black, tibiae yellow, black 

 at tip, with a black streak running inwards ; tarsi pale, broadly annu- 

 lated with black at the tips of the joints. 



Abdomen ovate polished, very slightly subpedunculate ; yellow 

 lanceolate ovate fasciae on front margin of second and fourth rings ; 

 on fifth and sixth they form con tin nous bands on the front margin, or 

 sometimes separate, when the fasciae are broader than those in front. 

 A slight line on the sixth ring. Tip spatulate as usaul. 



Length of body, .40; head and thorax together, .20; abdomen, .20 

 inch. 



9 . Head and thorax rather coarsely puncto-striated ; head not pilose 

 in front, the usual lining of silvery pile on each side of antennal 

 groove broader than usual; clypeus black, whole clypeal region silvery; 

 mandibles black, on upper edge of basal half an ovate whitish-yellow 

 spot, tips not paler than at base, though as a rule, the mandibles are 

 pale yellow, corneous at tip and black at base. Scape of antennae en- 

 tirely yellow, or stained black on the inside, flagellum black, joiuts 

 moderately long, slightly clavate. 



Thorax anteriorly puncto-striated, metathorax smooth, cpuite free 

 from hair, no distinct enclosure on meta-scutellum, but the fine striae 

 curve outwards from the mesial line, until towards the abdomen they 

 become transverse. In some specimens striae are slightly raised along 

 a curved line dividing off a hardly perceptible luuate enclosure. An 

 interrupted yellow fascia on prothorax, varying in size and intensity 

 of color, sometimes slightly fuscous, a yellow stripe on meso-scutelluni, 

 often absent or only represented by geminate dots; tubercle yellow. 

 Wings as usual slightly clouded, nervures dark, testaceous. Legs 

 much alike in coloration, coxae and femora black ; tip of fore femora
