ments, the well developed tibial spurs, the expansion of the 

 anterior tibiae at the apex, and in the close connection between 

 the front and the labrum. The females are found at the en- 

 trance of holes which they excavate in the ground. (Leconte.) 

 In Cebrio the labrum is separated by suture from the front, and 

 the anterior tibiae are entire. Cebrio bicolor Fabr. is found in 

 the Southern States. 



RHIPICERID^E Latreille. In this small group the head is 

 prominent and the maxillae have usually but a single lobe ; the 

 eleven-jointed antennae are inserted before and in front of 

 the eyes, under ridges, and are serrate in the females and 

 frequently flabellate in the males. The larva?, in their general 

 appearance, resemble those of the 

 Elateridcv or Tenebrionidce, be- 

 ing cylindrical, the head almost of the 

 same breadth as the body, which is 

 hard and honry, more or less dark 

 brown, and in Zenoa picea Beauv. is a 

 little more than an inch in length. 

 "The eighth segment is punctate all 

 around, and more densely than the 

 others. The posterior part of this segment is obliquely 

 truncate, and is closed posteriorly by a round, flat, horny 

 piece, punctate on the outside and which can, to a certain ex- 

 tent, be opened and closed like a lid, being connected by a 

 hinge superiorly, and an expanding membrane inferiorly. This 

 lid is to be considered as the ninth segment of the abdomen." 

 (Osten Sacken.) The larva, with the adult Zenoa picea, was 

 found under bark in Southern Illinois by Mr. Walsh. San- 

 dalus (S. petrophya Knoch, and tarsus, Fig. 427), with short 

 antennae, flabellate in the males, is found in various species 

 of cedars.

SCHIZOPODID^ Leconte. This small group is represented 

 by only a single species, Scliizopodus Icetus Leconte. It resem- 

 bles in form a Galleruca ; it is of a metallic green color, 

 coarsely punctured, with red elytra, and is nearly six-tenths 

 of an inch long. The head is bent down, closely affixed to
