COLEOPTEEOUS INSECTS. 227 



HORIA MACULATA. 

 PLATE XIX. Fig. 1. 



It is about sixteen lines in length, of a uniform 

 reddish-yellow colour, with seven spots of black on 

 each wing-case, six of which are arranged in pairs, 

 and the seventh occupies the apex. The mandibles 

 and antennae are shining black, and the legs are of 

 the same colour, except the base of the thighs, 

 which is the same as the body. According to the 

 observations of Lansdown Guilding, this insect de- 

 posits its eggs in the nest of the carpenter-bees 

 (chiefly in that of Xylocopa Teredo), and when the 

 larvae are excluded, they consume the food which 

 the bee provides for its proper offspring. It is not 

 rare in the vicinity of Rio Janeiro and other parts 

 of tropical America, and is usually found under the 

 bark of trees. It moves but slowly both when 

 walking and flying, and when handled emits a yel- 

 lowish liquid from its mouth of a peculiar odour.
