other specimens in the Museum belonging apparently to the 
same species, but too mutilated and shrivelled for accurate 
determination, are labelled “‘ Guayaquil and Colombia.” 
Cleobis Stollit, sp. n. 
(Preliminary diagnosis.) 
Colour. Head and mandibles entirely pale yellow ; upper 
surface of the free thoracic segments and of the anterior seven 
abdominal segments pale yellow in the middle, infuscate at 
the sides; palp with tibia lightly infuscate above, protarsus 
with its proximal third pale, the rest of it infuscate, the two 
tints gradually blending; first and second legs slightly infus- 
cate distally, third more strongly so, with a pale band round 
the distal end of the tibia and protarsus ; fourth leg with 
femur, tibia, and tarsus deeply infuscate, especially the latter 
two segments, which, however, have their distal ends ringed 
with flavous; coxe, trochanters, and tarsi of all the legs 
pale. 
Loc. Retalhuleu in Guatemala (Dr. O. Stoll). 
This species and the preceding resemble C. cube, Lucas, as 
described by Mons. Simon, in the structure and dentition of 
their mandibles, spinulose armature of protarsus of palp, &c. 
C. Stollii further resembles C. cube in having the upperside 
of the abdomen adorned with a median flavous band; but it 
appears to differ in having the first, second, third, and fourth 
legs infuscate, with a conspicuous flavous ring round the 
distal end of the tibia of the fourth. According to Simon 
C. cube has the first, second, and third legs pale, and the 
fourth reddish brown, with the base of the femur, extremity 
of the metatarsus, and the tarsus clear testaceous. 
C. Gervaisti: differs from C. cube in having no distinct 
median pale band on the abdomen, in having the second and 
third legs infuscate, and a wide, sharply defined, flavous band 
upon the proximal half of the protarsus of the palp.
