78 Objects for the Microscope. 



the elytra dull grayish-yellow thickly clouded with black, 

 and it has a curious pair of horns on its head. The mouth 

 shows a pair of broad curved and delicately fringed maxillae, 

 which deserve examination with a high power. The last 

 joint of the maxillary palpi is the largest, and the labial 

 palpi are very hairy. 



MOUTH OF ANCHOMENUS, 



a species nearly allied to Brachinus, a small green Beetle 

 found under stones. We observe the maxillae terminate 

 in a single hook, with two pair of palpi, and the tongue- 

 let having the paraglosssa mentioned in the mouth of 

 Brachinus. 



MOUTH OF CRIOCERIS. 



(Asparagus Beetle.) 



This abundant and pretty Beetle is found in the hot sunny 

 days of July laying eggs upon the asparagus plants. It is 

 blue and red, with the elytra marked in the form of a double 

 cross, yellow and blue. It belongs to the order Tetramera, 

 having four joints in the tarsi. 



The mouth displays a membranous two-lobed tonguelet, 

 the maxillae whitish and membranous, delicately fringed ; 

 the terminal lobe straight, the palpi filiform. 



MOUTH OF LADYBIRD, 



(Coccinella,) 



too well known to need description ; but it may be noticed 

 that it belongs to the last order of Coleoptera, the Trimera, 

 having only three joints in the tarsi. 



The mouth is very remarkable from the hatchet-shape of 

 the last joint of the maxillary palpi. The maxillae are 

 armed on the inner edge with a horny tooth. 



When the Coccinella is alive and in its youth, the circu- 

 lation of blood may be seen in the veins of the wing. 



MOUTH OF STENOPTERUS RUFUS. 



A black Beetle with red antennse, not common in Eng-
