408 INSECTA. 



They may be united in the single genus 



CALANDRA. 



In Calandra properly so called, the antennae are strongly geniculate, but 

 inserted near the base of the proboscis; their eighth joint forms an ovoid or 

 triangular club. 



C. granaria. But too well known; its body is elongated and brown? 

 thorax as long as the elytra and punctured. Its larva, known by the name 

 of weevil (genre), is the destroyer of our granaries. 



C. oryzse. Similar to the preceding, but with two fulvous spots on each 

 elytron. It attacks rice. 



C. palmarum. Length an inch and a half; club of the antennae truncated; 

 entirely black, with silky hairs at the extremity of the proboscis. It lives 

 on the pith of the Palms of South America. The inhabitants of that coun- 

 try consider its larva, called the ver-palmiste, as a great delicacy. 



There are several subgenera. 



FAMILY II. 



XYLOPHAGI(l). 



In our second family of tetramerous Coleoptera, we find the head 

 terminating as usual, without any remarkable projection, in the form 

 of a proboscis or snout. The antennae are thicker near the extre- 

 mity, or perfoliate at base, always short, and consist of less than 

 eleven joints in a great number. The joints of the tarsi are usually 

 entire, the penultimate being sometimes widened and cordiform in 

 others; in this case the antenna? always terminate in a club, either 

 solid and ovoid, or trifoliate, and the palpi are small and conical. 



These Insects mostly live in wood which is perforated and chan- 

 nelled in various directions by their larvae. When they happen to 

 abound in forests, those of Pines and Firs particularly, they destroy 

 in a few years immense numbers of trees, which are rendered use- 

 less for any purpose of art. Others do great injury to the Olive, 

 and some again feed on Mushrooms. 



We will divide this family into three sections. 



1. Those in which the antenna? are composed of ten joints at 

 most, sometimes terminating in a stout club, most commonly solid, 



(1) Wood-eaters.
