DESCRIPTIONS OF CALOPTENUS SPEETUS. 45 



This must, therefore, be accepted as the first description of the spe- 

 cies. 



lu the Eeport of the Geological Survey of the Territories for 1871 

 (published in 1872), he described the pupae as follows : 



General color, yellow (sometimes varied to light-brown, and at others a pale pea- 

 green), with a large proportion of black spots and stripes, also a few wliite dots and 

 lines; labrum and lower part of the face, mostly black; upper part of the face, the 

 vertex and cheeks yellow (or the prevailing color) ; a row of black dots on each mar- 

 gin of the broad, sulcate, frontal costa ; occiput with two lateral and one median dot- 

 ted lines of black ; a broad line of deep black starts behind each eye and crosses over 

 the entire length of the pronotum, widening and bowing upward near the middle of 

 the pronotum ; the immature, somewhat fan-shaped elytra [wing-pads] are black, with 

 a white dot on the disk near the base, from which proceed about ten or twelve white 

 rays, the dorsal or upper margia yellow ; dorsal and lateral portions of the abdomen 

 varied with white and black ; a triangular black dot on each side of each segment; 

 tip and venter yellowish. 



In his *' Seventh Annual Eeport" (1875), Mr. Eiley gives the follow- 

 ing additional characters of the perfect insect from living specimens, 

 also the following descriptions of the larva and pupa: 



Eegarding coloration, as with femur-ruhrum, it is quite variable, and the dead spec- 

 imens convey a very imperfect idea of the living colors, which are thus given in my 

 notes taken in the field. The more common specimens are yellowish-white beneath ; 

 glaucous across the breast and about mouth-parts; pale bluish-glaucous, often with 

 shades of purple, on the sides of the head and thorax and on the front of the face ; 

 olive-brown on the top of the head and thorax ; pale beneath, more or less bluish 

 above, and marked with black, especially toward base, on the abdomen. The front 

 wings have the ground-color pale grayish-yellow inclining to green, and their spots 

 and veins brown ; the hind wings, except a yellowish or brownish shade at apex and 

 along the front edge, and a green tint at base, are transparent and colorless, with the 

 veins brown. The front and middle legs are yellowish. The hind legs have the thighs 

 striped with pale glaucous and reddish on the outside and upper half of inside, with 

 four broad black or dusky marks on the upper edge, the terminal one extending be- 

 neath around the knee. The shanks are coral-red with black spines ; the feet some- 

 what paler with black claws; antennae, pale yellow; palpi, tip]3ed with black. In 

 the dead specimens all these colors become more dingy and yellow. Palpi and front 

 legs in some specimens tinged with red or blue ; the hind tibisB sometimes yellowish 

 instead of red, especially in the middle. 



Larva. — When newly hatched the larva is of a uniform pale gray without distinctive 

 marks. It soon becomes mottled with the characteristic marks, however. After the 

 first molt the hind thighs are conspicuously marked on the upper outside with a longi- 

 tudinal black line ; the thorax is dark with the median dorsal carina and two distinct 

 lateral strips pale yellow, the black extending on the head behind the eyes. The 

 sides of the thorax then become more yellow with each molt, the black on the hied 

 thighs less pronounced, and the face almost always black. The occiput and abdomen 

 above are mottled with brown, the former marked with a fine median, and two 

 broader anteriorly converging pale lines, the latter with two rather broken lateral 

 lines of the same color. 



Pupa. — The pupa is characterized by its paler, more yellow color, bringing more 

 strongly into relief the black on the upper part of the thorax and behind the eyes ; by 

 the spotted nature of the face, especially along the nidges, by the isolation of the 

 black subdorsal mark on the two anterior lobes of prothorax, and by the large size of 

 the wing-pads which, visible from the first molt, and increasing with each subsequent 

 molt, are now dark, with a distinct pale discal spot, and pale veins and borders. The 

 hind shanks incline to bluish rather than red. as in the mature insect.
