Fig. 69. — Arranged lo show some of the essential differences between the 

 species: L. oblongata, L. multitaeniata, and L. decemliueata. (A) Showing the 

 form and characteristic markings of the adult of L. obloiii^ala. (B) Adult of L. 

 multitaeniata, showing the more robust form and somewhat dilTerent type of 

 general color pattern sharply distinguishing it from both of the other species. The 

 elytral ground color is often dark ochre, sometimes even reddish. (C) The type 

 of L. deccmlineata used in these experiments, somewhat intermediate between the 

 two other species in bod}' form, and to a certain extent in markings. (D) Showing 

 the side view of a full-grown larva, with its color pattern. The ground color is 

 yellow and that of the adult somewhat variable. (E) Adult larva of L. multi- 

 taeniata, with the characteristic color pattern, (iround color is yellow as in L. 

 oblongata, but darker. (F) Shows the characteristic color pattern of L. deccm- 

 lineata; the ground color of the larvae is wine red.
