REPORT OF THE STATE ENTOMOLOGIST 1908 73 
Color brown varied with paler. Head fawn-yellow above, 
marked with blackish on the sides of the vertical facial carina, and 
around the ocelli internally, and bearing a mark shaped like the 
zodiacal sign for Aries along the middle of the head, the open end 
of the sign being in front. Antennae pale, about as long as the head 
Thorax brown more or less blackish on the sides, and in the rear 
above, the top of the mesothorax somewhat rufescent and shining. 
Between the bases of the middle legs a stout, thornlike spine, in- 
clined slightly to rear, arises from the mesosternum. Legs pale, 
the front femora being slightly darkened, and the tips of all tarsi 
indistinctly so. 
Wings hyaline with brown veins, cross veins more or lIcss_ bor- 
dered with brown in the costoradial strip, especially a few approxt- 
mated cross veins near the bulla, and a line of others, similarly 
approximated, extending from that point posteriorly across the 
wing [pl. 2, fig. 1]. 
Abdomen with a definite pattern of brown and paler yellow (pos- 
sibly, greenish in life), subcylindric, the lateral margins of segments 
5 to g suddenly dilated into wide, flat expansions, which double the 
width; each of these expansions obtusely rounded anteriorly, and 
produced posteriorly at its hind angle into a broad, flat, triangular 
tooth. These expansions are dark brown, paler basally, where they 
abut on a black line on the lateral margin of the abdomen. On the 
pale dorsum there are submedian blackish ( )- marks on each 
segment, the marks increasing in size posteriorly, becoming 
streaks on segments 9 and 10 [pl. 2, fig. 2]. On the ventral surface 
there are corresponding small and distant paired dots as far as the 
7th segment, diffuse on the 8th, and becoming elongate dashes on 
the 9th, and absent on the roth. The roth segment is short and 
cylindric, hardly surpassing the tip of the lateral teeth of the oth. 
There is no ventral prolongation of the gth sternite. Setae white, 
or slightly brownish at the extreme base. 
A single female imago from Sacandaga Park, collected by C. P. 
Alexander, Johnstown, N. Y. 
As the above description is going through the press, addi- 
tional specimens representing both sexes, are received from Mr 
Alexander. These he collected at Sacandaga Park on June 6, 1909. 
Mr Alexander writes that they were abundant, and that they kept 
high in air where they were conspicuous by reason of the wide 
abdomen. 
The male is of about the same size as the female, with white,
