stout, and the claws are simple and approximate, or even some- 

 what connate at base. 



The distinctions between this and the preceding tribe are 

 feeble, and to be found in our genera in the greater length of the 

 1st veqtral segment, and the different form of the claws. 



Two genera occur in our fauna, the second is represented by 

 two species of Criocei-is, introduced from Europe. 

 Protliorax constricted at the middle. Lema. 



Protliorax cylindrical. Crioceris. 



Tribe IV.— CLYTHRINI. 



This tribe consists of species of compact, stout, subcylindrical 

 form, having the protliorax margined at the sides, fitted closely 

 to the el3^tra; the front coxae are transverse, more or less promi- 

 nent, and have a large trochantiu. They are sometimes contigu- 

 ous, sometimes separated by the presternum, but the cavities are 

 closed behind. The 1st ventral segment is longer than the 2d; 

 the 4th and 5th are shorter at the middle and connate, so that 

 the pygidium becomes slightly inflexed. The elytra are lobed at 

 the sides, the epipleur* are apparent only near the base, and the 

 pygidium is exposed. Tlie head is large and deflexed; the eyes 

 are transverse, and sometimes eraarginate in front; the antennas 

 are widely separated, short, serrate, and 11-jointed; the mandi- 

 bles are sometimes much larger in the male, and the front legs 

 are occasionally elongated in the same sex. The legs are short 

 and stout, the tarsi broad, the claws simple or appendiculate. 

 The antenna} are not received in grooves in our genera. 



In the table of tribes given by Mr. Crotch (1. c. p. 19) the front 

 coxifi are represented as prominent and contiguous, but in the 

 table of genera (p. 27) it appears that they are so only in Ano- 

 nicea and Babia. 



Three groups are represented in our fauna: — 



Tarsal claws simple; 



Front coxse contiguons. Clythr^e. 



Front coxae separated by the presternum. Megalostomes. 



Tarsal claws appendiculate. Babi^b. 



Group 1. — Clythra:. 



But three species of this group occur in otir f^xuna, belonging 

 to the sub-genus Anomoea of Tituboea; one is found in the
