maxillary palpi, i.e. those feelers which are attached to the 

 maxilla', or inner jaws. In all the Erotylkhe they arc terminated 

 by a large flattened joint, but in the typical genus this joint is 

 bohly crescentic in its shape. 



That the exotic Erotvlides are fungus-eaters like our British 

 species, is evident from the observations made upon the larva 

 of Erotylus swrinamensis. The perfect insects are always to be 

 found about boleti, and within these fungi the larvae are taken. 

 They are rather large, white, flat-bodied grubs, with short, sharp, 

 sturdy jaws supported on a black head, which can be withdrawn 

 into a cavity in the front of the thorax. It is smooth, but on 

 the first segment of the body there is a soft, fleshy tubercle, 

 from which issues a pale, scented liquid, the object of which is 

 quite unknown. 



Mr. AVestwood, to whom I am indebted for the above account, 

 gives,in his "Introduction to Entomology," a figure of the larva 

 of an allied species, which in many respects is very much like 

 that of our English Erotylidae, save that it is much larger. 



The exact position of the family of the Langnriidae, and its 

 relationship to the other families, are matters respecting which

there has been much doubt. As, however, they arc placed next 

 to the Erotylidse in the British Museum, we will accept that 

 arrangement. 



This species, Fatua Weidmannii, comes from China. The legs 

 are very long, especially the first pair, which have the thighs 

 much elongated and slightly bent, and the tibiae of moderate 

 dimensions and rather boldly curved. The antennae are also 

 long, and have little tufts of stiff hair at each joint. 



The colour of the head and thorax is yellowish and partly
