ORTHOMERINUS.—GANYMELA. 359 
punctate, the prosternum transversely rugose, the subapical groove foveolate; first ventral segment 
broadly excavate. 
Length 6, breadth 3 millim. (¢.) 
Hab. Costa Rica, Guanacaste (Pittier). 
One specimen, found in June 1890. 
PSEUDORTHOMERIN US, gen. nov. 
Rostrum long, strongly arcuate; mandibles short, decussate; antennal club ovate; prothorax conical, 
tubulate in front; scutellum very small, rounded, free; elytra triangular, with the obliquely truncated 
humeri almost in a line with the sides of the prothorax; pygidium not visible; prosternum unarmed, 
declivous, the basal process subquadrate, flattened, partly covering the mesosternum ; anterior coxe very 
narrowly separated in the ¢, a little more distant in the ? ; legs moderately elongate; femora unarmed, 
clavate, the anterior pair very stout in the ¢, the intermediate and posterior pairs sulcate along their 
outer half beneath; tarsal claws subconnate at the base; body rhomboidal, flattened above, coarsely 
sculptured, clothed with a fine scattered vestiture beneath. 
Type, Ps. consanguineus, 
The species from which the above characters are taken is nearly allied to Orthomerinus 
pittieri, but differs from it in the non-protuberant prosternum, the clavate, sulcate 
femora, &c., the two insects being in other respects very much alike. Pseudorthomerinus 
has the compact form of Pachybaris porosa, Lec., but it is less convex beneath, the 
limbs are longer, the anterior coxe are narrowly separated, the scutellum is small, 
the body rhomboidal, &c. 
1. Pseudorthomerinus consanguineus, sp.n. (Tab. XVIII. figg. 14, 144, 3.) 
Shining, nigro-piceous or black, with a faint brassy lustre ; almost glabrous above, the punctures on the under 
surface and legs each bearing a minute, whitish, hair-like scale, the ante-coxal portion of the prosternum 
(¢) thickly clothed with narrow ochraceous scales. Head minutely punctate, transversely grooved between 
the eyes; rostrum a little longer than the elytra, stout, striato-punctate, smooth along the middle, in 
the @ more slender and more elongate, the antennz inserted at(¢) or behind (2 ) the middle. Prothorax 
broader than long, narrowing from the base, the sides slightly rounded anteriorly ; coarsely, closely 
punctate. Elytra deeply, narrowly punctate-striate, the interstices broad, closely punctate, becoming 
asperate towards the sides and apex. Beneath closely, the ventral segments 2-4 very sparsely, punctate, 
5 transversely depressed in the middle behind in the g. ‘ibis strongly unguiculate. 
Length 32-4, breadth 2-24; millim. (¢ 9.) 
Hab. Mexico, Playa Vicente (Sallé: 9); Guatremata, Mirandilla, Pacific slope 
(Champion: ¢ ). 
Two males and one female, evidently belonging to the same species, the female 
abraded beneath. ‘The elytra are triangular, and more attenuate at the apex than 
shown in our (fore-shortened) figure. 
GANYMELA. 
Ganymela, Pascoe, Ann. & Mag. Nat. Hist. (5) xvii. p. 427 (1886). 
A genus based upon a single species from Panama, remarkable amongst the Barids 
on account of the serrate femora. ‘The pygidium is not visible, and the anterior coxe 
are narrowly separated.
