REPORT OF THE STATE ENTOMOLOGIST I908 j;^ 



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 less bor- 

 dered with brown in the costoradial strip, especially a few approxi- 

 mated cross veins near the bulla, and a line of others, similarly 

 approximated, extending from that point posteriorly across the 

 wing [pi. 2, fig. i]. 



Abdomen with a definite pattern of brown and paler yellow (pos- 

 sibly, greenish in life), subcylindric, the lateral margins of segments 

 5 to 9 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 brovvm, 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 [pi. 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 loth. The loth segment is short and 

 cylindric, hardly surpassing the tip of the lateral teeth of the 9th. 

 There is no ventral prolongation of the 9th 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 

 .•\lexander. 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,
