RESEMBLANCES AMONG ANIMALS. 95 



Longicorns from the Philippine Islands most curiously 

 resemble, both in form and colouring, the brilliant 

 Pachyrhynchi, Curculionidas, which are almost pecu- 

 liar to that group of islands. The remaining family of 

 Coleoptera most frequently imitated is the Cicindelida?. 

 The rare and curious Longicorn, Colly rodes 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 Heliconidse which mimic their 

 own allies. Agnia fasciata, belonging to the sub-family 

 Hypselominae, and Nemophas grayi, belonging to the 

 Lamiinse, 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
