770 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 



Supra-anal plate triangular, acute at apex. Anal legs large, reddish on the edges. 

 Length, 30"'"'. 



Full-grown larva. — Body tapering a little towards the head and decidedly towards 

 the end. Head not so wide as the protboracic segment, acutely triangular, conical 

 seen in front, ending on the vertex in a subacute point and slightly notched. Face 

 dull brick-red, at the point above towards the apex darker ; the front is widely bor- 

 dered with straw-yellow ; head behind green. Body green, of the same hue as that 

 of the pine leaves; along the back is a broad dull brick-red dorsal stripe, wanting 

 on the prothoracic segment, and represented by isolated patches on the two follow- 

 ing segments and ending before the end of the supra-anal plate. This band is bor- 

 dered with a whitish-yellow line. Half way between this and the spiracular line is- 

 a straw-yellow even line, becoming white on the terminal second and third segments ; 

 it ends on the apex of the supra-anal plate, making its two sides white. The green 

 spaces between the lines and along the under side of the body are dotted with white. 

 A lateral infra-spiracular broad white line, interrupted at the sutures, becoming yel- 

 low towards the head. Above this line, along the posterior two-thirds of the body, 

 is on each segment an elongated lilac patch inclosing the black spiracles of the 

 latter, edged with white. Thoracic feet green ; under side of the body behind the 

 thoracic feet with a broad dull median lilac band, including the abdominal feet. 

 Supra-anal plate narrow, acutely conical, the tip lilac. The anal legs broad, angu- 

 lar, and edged with lilac. Length, 45""". Lintner does not, in his description, refer 

 to the stigmatal lilac patches. 



Pwj'a.— Chestnut-brown, with a rough, not produced head-case. Tongue-case 

 buried, parting the leg-cases, but terminating just before reaching the tips of the 

 wmg-cases. Incisures rounded. Posterior segments tapering. Stigmata black ; ter- 

 minal spine black, contracted at base, minutely bifid. Length, .95 to 1.10 inches.

90. The CHECKEREn pine sphinx caterpillar. 



Ellema pineum Lintner. 



A caterpillar like the foregoing, but with a dorsal row ot squares, and transforming 

 to a moth, which is readily distinguished from Ellema harrisii by the darker ground- 

 color of its wings, the absence of the gray shades, and its much less distinct mark- 

 ings. (Lintner.)

Mr. Lintner, in his Entomological Contributions contained in the 

 Twenty-third Eeport of the New York State Cabinet, describes the 

 male and female of this pine sphinx, and also describes the larva as 

 follows : 



Larva. — Length, 2 inches. Color, grass green. Head subtriangular, green, bor- 

 dered with bright yellow, within which, at the apex, is a /\ of black. Body subcyl-
