spike-like form. Some of these beetles are very prettily 
marked, and are worthy of notice on account of their 
colouring. The Doryphora tessellata which is found in 
our neighbourhood, though I have never seen a specimen 
of it here, is one of the finest of these. Its ground 
colour is yellow, and its elytra are crossed by five rows 
of square chestnut spots. The thorax is plain chestnut. 
The name Chrysomelides, i.e. " Golden Apples," is 
sometimes given to beetles of this sort. As their 
figures are rounded, and their colours rich, this name 
is rather appropriate, but it has been somewhat capri- 
ciously used. There is a considerable quantity of 
these inse£ts here, and they present an agreeable 
variety of colours such as scarlet, azure, gold, and green, 
brought out with lustre. They are all plant-eaters, and 
some of them are gregarious in their habits. 
The Trimera, Three-jointed, or as the Rev. J. G. 
Wood has it, Pseudotrimera, False Three-jointed, is 
another general division of Coleoptera. Mr. Wood 
asserts that, though the tarsi of these insecls seem to 
have only three joints, they have really four, the third 
one being very minute, and hid in the doubly lobed end 
of the second. This division contains a somewhat mis- 
cellaneous collection of beetles, and some of the families 
in it appear to be but slightly related to one another. 
The families or groups with which we have mainly to do 
at present are the Erotylidae and Coccinellidae. Ero- 
tylidae means " little darlings," being derived from the 
Greek erotis, darling. There are about 130 species of 
this genus, and most of them are small, and some of 
them are very beautiful. Their bodies are mostly oval 
and generally raised in the middle, and their antennae
