TYRANNION.—PHILONIS. 603 
Hab. Panama, Bugaba, Volcan de Chiriqui (Champion). 
Four specimens. In this insect the third elytral interstice (instead of the second) is 
swollen at the middle, and has a faint oblique whitish streak below the base. 
23. Tyrannion basalis, sp.n. (Tab. XXIX. fig. 23.) 
Very similar to 7’. breviculus, but with a transverse fulvous patch at the base of the elytra (not reaching the 
suture), followed by a faint, oblique, whitish, humeral streak, the rest of their surface mottled with 
fulvous and black, the usual whitish spot on the disc towards the apex present, the third and fifth inter- 
stices each with a short line of coarser setiform black scales below the base, the second and third simply 
convex; the eyes less approximate; the rostrum a little shorter, reaching to the middle of the intermediate 
cox; the femora rather sharply dentate. 
Length 34, breadth 2 millim. (<.) 
Hab. Panama, Volcan de Chiriqui (Champion). 
Two males. 
PHILONIS, gen. nov. 
Rostrum very stout, curved, nearly reaching the metasternum, the antennee inserted at about the middle, the 
funiculus 7-jointed, the club oblong-ovate, compact; eyes large, laterally placed, coarsely facetted, 
depressed, covered by the prominent ocular lobes of the prothorax, the prothorax itself transverse, with 
the base bisinuate ; scutellum visible; elytra oval, broader than the prothorax, with the alternate inter- 
stices costate, the tenth row of punctures short ; mesosternum horseshoe-shaped ; metasternum short, the 
episterna broad; ventral segments 2-4 short, equal in length, together not longer than 1, the sutures 
straight, the intercoxal process broad ; legs short and stout ; femora without trace of tooth ; tarsal claws 
simple; body ovate, robust, densely and coarsely squamose, 
A single species is referred to this genus*. It is related to Hubulus, Tyrannion, 
Metriophilus, &c. 
1. Philonis inermis, sp.n. (Tab. XXIX. figg. 24, 24 a, 6.) 
Ovate, robust, black, the antenne ferruginous; the prothorax sparsely, the rest of the surface densely, 
clothed with coarse whitish or brownish-white scales, the head, under surface, and legs with intermixed 
reddish scales, the elytra with two transverse fascie (one at the base, the other beyond the middle), more 
or less connected along the suture, similarly coloured. Head rugulosely punctate, depressed on each side 
(and in one specimen carinate) between the very widely separated eyes; rostrum rugousely punctate at 
the base, sulcate at the sides to near the tip, and for the rest sparsely, finely punctate. Prothorax strongly 
transverse, rounded at the sides anteriorly, much narrowed and feebly constricted in front; coarsely, 
rugosely punctate, and also carinate. Elytra transversely convex, much wider than the prothorax, rapidly 
narrowing from a little below the base, the shoulders rounded; seriate-punctate, the interstices 3, 5, 7, 
and 9 costate. Beneath opaque, closely punctate. 
Length 5;4,—63, breadth 2;%-37? millim. 
Hab. Mexico, Teapa (H. H. Smith), Tapachula (Hoge). 
Two specimens, probably male and female, the rostrum being rugose at the base in 
one from Teapa. In this insect the vestiture of the elytra is dense and imbricate, 
* There is a Brazilian insect in the British Museum labelled with the MS. name Celosternus obesus, Jekel, 
that possibly belongs here ; it is very like P. inermis, but has the prothorax dilated at the base.
