that it is doubtful whether all may be truly one species. The head is in some a little 
narrowed in front; and the antennee vary somewhat in thickness, and in the colour of 
their apical portion, which is sometimes clear yellow, sometimes infuscate; the dark 
band on the abdomen is sometimes definite and nearly limited to the fifth segment, but 
in other cases is indefinite and darkens slightly the hind body nearly to the base. 
12. Homalota longifrons. 
Depressa, parallela, subtilissime punctulata, subnitida, fusco-testacea, capite abdomineque fuscis, pedibus 
testaceis; capite oblongo, anterius impresso ; antennis brevibus, articulis penultimis transversis. 
Long. 17 millim. 
Hab. Guatemata, Guatemala city and San Gerénimo (Champion). 
One of the most minute insects of the family. Antenne very short; the basal joints 
testaceous, the others more or less infuscate; third joint quite small; fourth to tenth 
transverse, each broader than its predecessor ; terminal joint rounded, not large. Head 
oblong, deeply impressed in front. Thorax not broader than the head, rather elongate, 
but not quite so long as broad, straight at the sides, but the base a good deal rounded, 
depressed along the middle, punctuation almost invisible. Elytra longer than the 
thorax. Hind body narrow, almost broader at the fifth segment than at the base, 
punctuation invisible. Legs short, yellow. 
Five individuals of this mite have been found. Though similar in many points to 
H, evanescens, it is abundantly distinct. 
13. Homalota diffinis. . | 
Nigro-fusca, antennarum basi pedibusque fuscis; antennis mediocribus, articulis nullis transversis ; prothorace 
subquadrato, sparsim punctato ; elytris crebrius parum subtiliter punctatis, quam prothorax longioribus ; 
abdomine apicem versus subattenuato, sparsim punctato. 
Long. 33 millim. 
Hab. Panama, Volcan de Chiriqui 8000 feet (Champion). 
Antenne rather elongate, but little thickened externally, the two basal joints sordid 
red, the rest nearly black; second and third joints rather elongate, the latter very 
slightly the longer; fourth joint rather small, not transverse; fifth to tenth differing 
very little from one another, each about as long as broad; terminal joint of moderate 
length, not quite so long as the two preceding together. ‘Thorax a good deal narrower 
than the elytra, nearly as long as broad, nearly straight at the sides, hind angles not 
rounded. Elytra rather longer than the thorax, more closely punctate than the rest of 
the upper surface. Hind body shining, with the basal three segments sparingly, the 
two following still more sparingly punctate. Legs infuscate yellow, the femora darker, 
the tibiee without porrect seta on their middle. 
Two individuals, in bad condition. The species has a very ordinary appearance, and, 
indeed, extremely resembles H. chiriquensis; but it has the middle cox more than
