Black, sliming ; head and thorax covered with a pale pile, clypeus, 

 except at the extreme base ; the greater part of the labrum in front and 

 at the sides, a mark at base of mandibles, two small dots behind the 

 ocelli, pronotum, tegulee in front, the greater part of the scutellum, the 

 apical fourth of the two anterior femora and tibia), except at the extreme 

 apex ; basal joint of the tarsi in front, apex of four posterior femora, 

 the greater part of hind tibiae in the middle, posterior trochanters, base 

 of femora and apex of coxse, a faint spot over anal segment, a large 

 oblong spot over the hind coxae, and the blotch white. 



The antennae are somewhat longer than the abdomen, the middle 

 joints being thickened ; on the pleurae are scattered punctures ; they are 

 almost shining and faintly pilose ; the scutellum is smooth, shining, 

 vertex slightly contracted, sheath of saw projecting, pilose at the apex ; 

 palpi annulated with fuscous-white, and the hinder tarsi are quite black. 

 Wings hyaline at the base, smoky at the apex. The nervure in the 

 lanceolate cellule varies in form, it being sometimes shorter, at other 

 times longer contracted. 



In the <? the antennae are longer and thicker, the joints being also 

 more closely compressed together ; clypeus and labrum almost wholly 

 white ; anterior legs have more white in front ; white band on posterior 

 tibiae smaller ; the anal lobes are white, and so also are the posterior 

 abdominal segments at the side. The scutellum is black. 



Length 45 lines. 



Ab. a. Scutellum black ( ? ). 



The amount of white on the mouth, legs, &c., varies 

 in intensity in both sexes. 



The larva has been described by Van Vollenhoven 

 and Kaltenbach. The former naturalist observed the 

 9 on the 8th of April, about half past eleven (the 

 thermometer being at 60 F.), flying about wildly 

 around an elder bush and settling occasionally on the 

 leaves. This specimen he caught and placed in a glass 

 along with a branch of elder. When in the shade it 

 remained very quiet and even fell and lay upon its 

 back, but when the glass was placed again in the 

 sunshine it revived ; at first it moved the antenna3 

 violently, and then commenced to run rapidly about; 

 By 4 o'clock it had laid twelve eggs in little receptacles 

 in the leaves embedded in the lower epidermis. The
