90 TWENTY-THIRD REPORT ON THE STATE CABINET. [222] 



cross-wise. The rest are rounded, somewhat elongated transversely, 

 which is also the case with those on the dorsum. The larva is 

 entirely naked, and all except the collar thickly granulated. Head and 

 feet black, the first granulated and wrinkled in front, with the clypeus 

 furrowed cross- wise. In its youth the larva has a quite different appear- 

 ance, it having stripes instead of spots. The young larva, (length thirty 

 millimetres) which I have before me is velvety black with light yellow 

 stripes, the dorsal stripe slightly mixed with reddish-yellow, and the 

 broad side-stripes dotted with black. The skin is not granulated, bat 

 each of the middle segments is adorned by four tiny warts surmounted 

 each by a rather long bristle. The head is smooth, black, with yellow 

 markings in the middle and on the sides. 



It is probable that the larva of C. intermedia changes in its appear- 

 ance after its last molting in a similar manner. In this stage it has 

 the ground color and the three rows of spots in common with luci- 

 fuga,) but the color, number and division of the spots are different. 

 The spots of intermedia are lilac, those of lucifuga orange ; the first 

 has thirteen dorsal spots, the other twenty-five, etc., etc. The larvae 

 of lactuccB and campanula have no resemblance whatever with that of 

 intermedia. The larva of umbratica has more resemblance to it, but 

 here the differences in color and markings are too striking to necessi- 

 tate a comparison.
