RESEMBLANCES AMONG ANIMALS. 95 
Longicorns from the Philippine Islands most curiously 
resemble, both in form and colouring, the brilliant 
Pachyrhynchi,—Curculionide, which are almost pecu- 
liar to that group of islands. The remaining family. of 
Coleoptera most frequently imitated is the Cicindelide. 
The rare and curious Longicorn, Collyrodes lacordairei, 
has exactly the form and colouring of the genus Collyris, 
while an undescribed species of Heteromera is exactly: 
like a Therates, and was taken running on the trunks 
of trees, as is the habit of that group. There is one 
curious example of a Longicorn mimicking a Longicorn, 
like the Papilios and Heliconide which mimic their 
own allies. Agnia fasciata, belonging to the sub-family 
Hypselominz, and Nemophas grayi, belonging to the 
Lamiine, were taken in Amboyna on the same fallen 
tree at the same time, and were supposed to be the same 
species till they were more carefully examined, and 
found to be structurally quite different. The colouring 
of these insects is very remarkable, being rich steel-blue 
black, crossed by broad hairy bands of orange buff, and 
out of the many thousands of known species of Longi- 
corns they are probably the only two which are so 
coloured. The Nemophas grayi is the larger, stronger, 
and better armed insect, and belongs to a more widely 
spread and dominant group, very rich in species and 
individuals, and is therefore most probably the subject 
of mimicry by the other species. 
Beetles mimicking other Insects. 
We will now adduce a few cases in which beetles
