IN COLEOPTEROUS INSECTS. 461 



Observations. This insect very much resembles the fol- 

 lowing, but maybe distinguished by its narrow thorax, the 

 marking of the head and feet, its size, the time win n it ap- 

 pears, and, above all, by the difference in the form of its max- 

 illary appendages. Another great peculiarity, not mentioned 

 in the description, is the existence of two bags, analogous to 

 the caruncles of the prothorax of Malachius. These bags 

 issue from the sides of the second segment of the abdo- 

 men, within the pulmonaria and under the spiracida dor- 

 sal 'in ,- and being capable 01 considerable distention, they seem 

 to be composed of one lobe only. During life the abdo- 

 men is much longer than the elytra, but it contracts much 

 in drying. Neither this nor the next species live upon prey. 

 They are both always found feeding on flowers, live long, 

 and many, when about to die. grasp with their mandibles the 

 petal of a flower, and may be found dried up in that state.
