ENTOMOLOGT. 97 



would account for what I have mentioned; but 

 of this I can give little information. The Mahoe 

 {Hibiscus tiliaceus), the Bastard Cedar {Guaziima 

 idmifoUa), the Mammee Sapota {Lucuma mammosa), 

 the Locust {HymencBa couharil), and the Trumpet-tree 

 [Cecropia peltata), are some of the forest-trees, with 

 others called Burn-wood and Down-tree, of which I 

 know not the systematic appellation, unless the latter 

 he the Ochroma lagopus of botanists. But there is one 

 tree which grows numerously in that locality, which 

 I suppose to have some influence on the Lepidoptera 

 and Hymenoptera ; it is provincially called the Po- 

 tatoe-wood ; it is at that time covered with blossoms, 

 which, though they grow in thick racemes, offer 

 nothing pleasing to the sight or the scent. But these 

 form the centres of attraction to the insects I have 

 named ; Pierides and Thecla in particular flutter 

 around the summits in considerable numbers, and 

 swarms of small beetles and flies. The Bauhinia 

 displays its elegant blossoms, and in one corner a large 

 patch of Cassia attracts Papiliones and Coliades ; but 

 in general there is an almost total lack of the flower- 

 ing herbaceous vegetation that fringes the roads in 

 most other places. It is remarkable also that the 

 trees in these woods are nearly, if not quite, destitute 

 of epiphyte Orchidacece, which are so abundant on 

 Bluefields Mountain at a similar elevation, that hardly 

 a tree is without one or more specimens. But in 

 other respects the character of the vegetation in the 

 two regions differs greatly. 



This district I habitually visited every alternate 

 week, very frequently spending eight or ten days at
