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.
