f)12 COLEOI'TERA. 



tened tubercles spinulated above ; on each side of the first 

 abdominal segment is a yellowish spot, and there is a broad 

 yellowish spot in the middle of the fourth segment, and one 

 on each side. On June 28th we found several fully grown 



t/ ^ 



larvre a quarter of an inch long, transforming into pupa', 

 with a freshly transformed beetle. The larva begins the opera- 

 tion })y attaching very firmly, with a sort of sillvy gum, its tail 

 to the leaf, the point of attachment not being the extreme tip, 

 but just before it, where the tip of the abdomen of the pupa is 

 situated. Meanwhile the body contracts in length and widens, 

 the head is bent upon the breast, and in about twenty-four 

 hours the skin splits open and discloses the pupa. The body 

 of the pupa is black ; the head is also black, and 

 the prothorax is black and yellowish pink, with 

 a black dot on each side, and a smaller black 

 dot on each edge ; the mesothorax, wing-coyers, 

 scutellnm and legs, are shining black. The al>- 

 dominal rings are pale flesh-colored, with two 

 rig. 511. rows o f i ai -g e black spots on each side, the spots 

 being transverse ; the terga of the fourth to the seventh seg- 

 ments are separated, the body being arched and leaving 

 a deep furrow between. The beetle is orange yellow, 

 with a black head and prothorax ; the side of the pro- 

 thorax is whitish, with a central diamond-shaped white Fig - 51 ' 2 - 

 spot, and behind it a much longer whitish spot. The beetle 

 derives its specific name from the two black dots on the elytra. 

 It hibernates, and might be used to clear house-plants of plant- 

 lice. The Nine-spotted Coccinella, C. novemnotata Ilerbst 

 (Fig. 511, and pupa), and the Three-banded Coccinella, C. tri- 

 fasciata Linn. (Fig. 512), are also not uncommon species. 



The Fifteen-spotted Lady-bird, Mysia \5-punctata Olivier, 

 is black on the head and prothorax, with seven black spots on 

 the brownish red elytra, and a black spot on the scutellum ; it 

 is seven-twentieths of an inch in length. The larva closely re- 

 sembles that of Coccinella, but along the body are six rows of 

 stout spinnlated spines ; the upper surface of the body is black, 

 with a pale spot on the hinder edge of the prothoracic ring ; 

 the body is pale beneath. It is half an inch long. The pupa 

 is pale, not black like that of the Coccinellaj known to us, and
