blunt head and knobbed antennae. The burrows (fig. 162) of the 

 beetles and larvae in wood and under bark are often of a character- 

 istic pattern for each species. 



Lamellicornia. — The beetles (fig. 44) of this section have the last 



few joints of their short an- 

 tennae developed into leaf- 

 like extensions. The tarsi 

 are five -jointed. Many 

 of them are of large size 

 (fig. 122), with broad, 

 heavy bodies, and in many 

 cases the males have curi- 

 ousl} T developed horns on 

 the head or prothorax. 

 Their legs are rather short, 

 and usually end in very 

 stout claws. Some of 

 them have the forelegs toothed and fitted for burrowing in the soil. 

 Many of the tropical species are renowned for the beauty and elegance 

 of their form and color. The larvae are fat grubs, with very short legs, 

 a prominent head, and a thick, soft abdomen. They often lie in a half- 

 curled position. The adults are frequently found upon flowers, and 

 many eat the leaves of plants. The larva- live in the soil, feeding 

 upon roots, or in manure, or 

 in decaying wood, or in ants' 

 nests. To this section belong 

 the sacred Scarabams of the 

 Egyptians, the familiar June- 

 bugs or May-beetles (family 

 Scarabaeidre), and the stag- 

 beetles (Lucanida?) , the males 

 of which have enormous jaws. 



STREPSIPTERA. 



This order (family Stylo- 

 pidae) includes a few tiny in- 

 sects whose curious structure 

 and habits have long puzzled 

 entomologists. The male has 

 large eyes and a short, 

 small abdomen. The elytra are very rudimentary. These males 

 live but a short time, but are very active. The female is a 

 mere sac, a head and a larger body, without legs and wings. 

 The larvae and the female live in the bodies of other insects, 

 wasps, bees, and certain Hemiptera. They pass through a com-
