LANTHANUS: 109 
Hab. Muxico, Teapa (Sallé); Brrrish Honpuras (Blancaneaur) ; GUATEMALA, Cerro 
Zunil, Zapote, San Gerdnimo, Purula (Champion); Panama, Volcan de Chiriqui 
(Champion). 
Found in abundance at Zapote, sparingly elsewhere. The spotted and unicolorous 
forms were collected together in about equal numbers at Zapote and also in British 
Honduras. The Mexican examples are rather larger than the others. JL. variegatus 
varies considerably in size, as well as in colour; the unicolorous variety is of a more 
brilliant tint than the spotted form. One of the latter from Zapote is figured. 
2. Lanthanus nitidus. (Tab. V. fig. 13.) 
Obovate, golden-bronze, very shining. Head finely and somewhat thickly punctured ; antenne with joints 1-8 
testaceous, the club piceous; prothorax moderately transverse, the basal groove deeply impressed laterally, 
the disc with a very shallow almost obsolete oblique groove on each side behind, the surface sparsely and. 
moderately coarsely punctured; elytra very much broader than the prothorax at the base, smooth ; 
beneath piceo-seneous ; legs testaceous, the femora darker. 
Length 2 millim. 
Hab. Mexico, Cerro de Plumas (Hége). 
One example only. This species is of more obovate shape than L. variegatus; the 
thorax has the oblique fovea on each side of the disc barely indicated, and the basilar 
groove more deeply impressed laterally ; and the elytra are relatively broader. 
Fam. @DEMERIDA. 
This is a family containing a large number of species in all parts of the World, and 
most Oceanic islands possess one or more representatives. No systematic attempt has 
hitherto been made to deal with the very numerous species inhabiting the warmer parts 
of the globe, an immense number of which exist in collections, those of Europe and 
North America only having been worked out as yet; and the comparatively few species 
described from tropical regions have been in many cases erroneously referred to Kuropean 
genera. A large number of species are now recorded from Central America, nearly all 
of which are described as new; one only, and that an introduced one from Europe, has 
hitherto been noticed from within the limits of our fauna. The inextricable confusion 
existing at present amongst authors as regards the true limits of many genera, some 
of which have not been really characterized*, has given me considerable trouble in 
dealing with such a large amount of material. The form of the mandibles, which 
ig not noticed by many authors, affords a good generic character In some cases; 
while the clothing of the soles of the tarsi and the toothing or not of the claws often 
cannot be depended upon. The false twelfth joint to the antenne in many genera is
