150 GENUS CARIBLATTA (oRTHOPTERA) 



debris of every kind. The tropical species of the present genus 

 found by the author, in most cases inhabited preferably the 

 heavy forest, where numbers were discovered among the loose 

 leaves resting on the leaf mould on the ground, in dead agaves 

 and in the bromeliads on the branches of the trees. Of the 

 material collected, it is interesting to note that C. insularis was 

 found to be the most numerous Orthopterous insect in the brome- 

 liads growing on the branches of the trees at Montego Bay, 

 Jamaica. In an area of a few feet of leaves and leaf mould in 

 the hillside forest at Stony Hill, Jamaica, which was minutely 

 examined, series of C. reticulosa and C. cuprea and a number 

 of specimens of C. punctulata were secured; these species of the 

 present genus forming a large proportion of the Orthopteran life 

 there found. These diminutive insects ran about with great 

 speed and took wing readily, though usually flying but short 

 distances. When in flight, they appeared very much like small 

 brownish moths. The series of C. imitans was secured at Corozal, 

 Panama, also in the dead dry leaves and leaf mould of the jungle. 

 Material of C. punctulata, however, was secured both in Cuba 

 and Jamaica, under various rubbish in fields of short grass, the 

 species appearing to be widely distributed in the open as well as 

 in the forest. 



Structural Characters. — The species are decidedly similar in 

 many structural features. Slight size variation is found within 

 individual species (except in punctulata and lutea), but all of the 

 species show only slight differences from each other in this feature. 

 In form the species are constant, and appreciable differences in 

 this character are found between some. The head is the same 

 throughout the genus, the maxillary palpi alone showing slightly 

 different degrees of attenuation in different species, but in occa- 

 sional individuals these appendages are deformed, on one side or 

 both, and the character is in consequence dangerous to rely upon 

 when determining single specimens. The male genitalia, but 

 particularly the subgenital plate and its appendages, furnish 

 strikingly different characters in the majority of the species and 

 show hardly any variation, (only in punctulata arc distinct 

 individual differences found as discussed on p. KK), footnote 16). 

 The female genitalia offer much less striking differences; in but a 

 few species showing slight differences, in the degree of mesal 

 emargination of the supra-anal plate and of the production of
