MALTHINUS. 103 
the last four joints yellow; the palpi are pale, with darker apical joints. The thorax is 
narrow, yellow, with a shallow depression on each side. The elytra are less evidently 
punctured than in the last species, and hence are a little more shining; and the margins 
of their attenuated apices are faintly yellow on the inner side. The knees of the two 
posterior pairs are black, the front pair indistinctly fuscous ; the tibiee and apices of the 
tarsi are dark. The underside, with the exception of the apex of the abdomen, is yellow. 
Eight specimens were taken by Champion.

The head is nearly twice the width of the thorax, the space between the large sub- 
globose eyes being as wide as or rather wider than it; both head and thorax are shining 
and only very obsoletely punctured, but with irregularimpressions. The thorax isas long 
as wide, rather convex above, with depressed sides, which are a little rounded and very 
narrowly yellow. The antenne are long, and as thin and thread-like as in European 
Malthini, their basal joint alone yellow. The elytra, rather more than half as long as 
the body, are from their base entirely dark, excepting their apices. It will be observed 
that they are thus much shorter, both in this and the following species, than in any 
English Malthinus or Malthodes with which they can be compared. ‘This species has 
something of the appearance of Malthodes flavo-quttatus, and is of about the size, and 
has the antenne of the length of those of the male, of that species; but its head is much 
wider, and its thorax is of a much narrower, more cylindrical form than that of any 
species of that genus. 
A single specimen taken by Champion at Calderas is the one figured; two others 
were collected by him atSanGerdnimo; another specimen, apparently identical with these, 
but which has lost its antenne, was taken by Mr. Salvin near the city of Guatemala. 
4, Malthinus terminalis. 
Nigro-piceus, nitidus, capitis fronte, prothoracis lateribus pedibusque testaceis, his tibiis tarsisque fuscescentibus. 
Long. 4-5 millim. 
Hab. Panama, Volcan de Chiriqui (Champion). 
Pitchy black, shining, impunctate; head obscurely yellow with the base pitchy ; 
antenne a little shorter than the body, slightly serrate, dark pitchy black with the two 
apical joints yellow; sometimes only the terminal one is pale; palpi dark. ‘Thorax 
pitchy, with the sides obtusely pale, rather wider than long, with a central channel, 
which is sometimes very obsolete. Elytra shining, faintly coriaceous, entirely pitchy. 
Legs pale; the tibiz are fuscous, at least at their apices, and the tarsi dark, especially 
the third and fourth joints. The metathoracic epipleure are whitish.
