NOTES ON THE BUTTERFLIES 12. CERATINIA FENESTELLA (Hew). Found at the Cayo. A delicate little insect with a slow fluttering flight always keeping close to the herbage. In woodlands only. It does not occur in the northern districts. It is rather an uncommon insect. 13. NAPEOGENES TOLOSA (Hew). This is another butterfly which is extremely local in its range. The only place that I have ever captured or seen it is the Cayo, and only in one very small area in that district. This was along a pathway which ran by the side of the river close to the town of the Cayo. For a distance of about fifty yards along this pathway these insects were found in companies of five or six. I have searched the Cayo District pretty well and never saw this butterfly anywhere else except in this one very small area. It is a shade lover and its flight is weak. It is fond of resting on the leaves of small bushes. In appearance it very much resembles a Mechanitis. 14. DIRCENNA KLUGII (Hub). As far as this Colony is concerned I have only taken this insect sparingly at the Cayo. I have not come across it anywhere else. In Guatemala it is exceedingly common.
