OF BRITISH HONDURAS 8. MECHANITIS DORYSSUS (Bates). I have found this insect at San Pedro Sarstoon, where it is fairly abundant. It is altogether absent from the northern districts. 9. MECHANITIS UTENAIA (Reak). This is a variety of the preceding, and I have taken it plentifully in the woods around the Cayo in the west. 10. MECHANITIS LYCIDICE (Bates). A common forest butterfly in the Western District. It flies with fluttering and slow move- ments keeping close to the undergrowth. Numbers of them are often seen together. I have never seen any of this genus of Mechanitis in the northern districts. II. CERATINIA DION(EA (Hew). I have met with this butterfly in the Southern and Western and also in the Stann Creek Districts, but I have never seen it in the north of the Colony. It is very local and is never found outside the forest belt. Here it is observed only in certain circumscribed areas, but where a single specimen is found others also will be seen. It has a feeble fluttering flight and is easily captured. Its resemblance to a Mechanitis is very strong, but the row of yellow spots along the margin of the wings at once distinguishes it.
