SAGRIN.E. 
3 
Key to the Divisions of the Chrysomelicuc. 
A. Mouth placed anteriorly. 
a. Antennae widely separated at base ; elytra 
of hard texture. 
a'. Intermediate ventral segments not 
medially constricted ; pygidium not 
exposed. 
cf. Thorax without distinct lateral 
margins, head produced, eyes 
prominent, prosternum exceedingly 
narrow Eupodes. 
Ir. Thorax with distinct lateral margins 
(rarely without), head not produced, 
eyes not prominent, prosternum 
broad Cyclica. 
h ' . Intermediate ventral segments con- 
stricted; pygidium usually exposed . . Camptosomes. 
h. Antennae not widely separated at base, 
generally closely approximate ; elytra 
more or less soft in texture Tricuostomes *. 
B. Mouth not normal, small, hidden or nearly 
so Cryptostom.es *. 
Division EUPODES. 
Key to the Subfamilies. 
A. Antennae separated by entire front of head. 
a. Posterior femora very strongly incrassate : 
large sized insects of brilliant metallic 
coloration Sagrinee. 
h. Posterior femora only slightly incrassate : 
much smaller insects, less brilliant, rarely 
metallic Criocerincn. 
B. Antennae not separated by entire front of head . Donaciinas , 
Subfamily I. SAGRINAE. 
Head porrect, constricted at the neck ; antennae filiform with 
robust cylindrical joints ; thorax not margined laterally ; elytra 
at the base much wider than the thorax; legs robust with strongly 
thickened posterior femora, these in the S furnished beneath with 
one or more teeth ; first abdominal segment twice as long as 
any of the following segments. 
The Sagrinee are the largest and most brilliantly coloured of all 
the Ohrysomelidas. Most of them are beautifully metallic and in 
shape have a slight resemblance to certain species of Longicorns. 
Little or nothing is known of their larval state or habits, and 
observations in these respects are greatly needed. 
A single genus, Sagra.
