dome a little over 4,000 ft. high. Seen from La Hotte, this 
mountain seems still to be capped with at least a square 
mile of dark forest. It is entirely unknown entomological- 
ly. Botanically it is related to La Hotte, but with some 
peculiar forms. Between Bonnet Carre and the eastern- 
most rainforest (at about 2,000 ft.) on La Hotte there are 
20 miles or more of low, dry ridges. The high ranges of 
the central part of the La Hotte massif (Pic de Macaya, 
Pic du Formon, and Pic de la Gde. Colline on the map), 
and apparently also most of the lower ranges to the west 
almost to the coast, are very heavily forested. On La Hotte 
itself is a completely . unbroken tract, without even trails, 
probably 3 or 10 miles across the narrowest way. The 
forest is of two kinds: fine pine with unusually thick un- 
dergrowth and with thick moss and pine needles on the 
ground, and lower, denser, very wet cloud forest, without 
pine, fringed with cutting climbing bamboo and other 
atrocious plants. It is in the La Hotte region, of all Haiti, 
that there is to-day the best chance of finding novel forms 
of life, and it is undoubtedly there that natural conditions 
will persist longest. 
Descriptions: Wherever in the following pages definite 
proportions are given — for instance the relative width of 
head and prothorax — they are based on actual measure- 
ments made under a binocular microscope. Estimates made 
without measuring are likely to be surprisingly inaccurate. 
I have invariably measured the width of the head across 
the eyes at the widest point ; width of prothorax, at widest 
point ; length of prothorax, at middle, regardless of whether 
or not the anterior angles project forward; width of base 
of prothorax, between angles ; width of apex, between most 
advanced points of angles. 
Ardistomus alticola n. sp. 
Very stout and convex; black, shining but not metallic; 
not spotted ; legs piceous ; antennae, palpi, and tarsi rufous. 
Head with front margin of clypeus faintly convex; front 
lightly, vertex not distinctly transversely impressed. Pro- 
thorax suborbicular, moderately narrowed in front; lateral 
margins distinct to base; disk with usual fine middle line 
and anterior transverse impression; not punctate. Elytra
