Diorymerus perlevis (p. 214). 
To the locality given, add :—Guatemata, Trece Aguas in Alta Vera Paz (Schwarz & 
Barber, in U.S. Nat. Mus.). 
A second specimen of this species has now been seen. It is much larger than the 
Mexican type, measuring, length 32, breadth 22 mm. 
20 (a). Diorymerus ruber, sp. n. (Tab. XXIII. figg. 14, 14 @.) 
Rhomboid-ovate, narrow, convex, shining, rufous, the anterior femora oad. tibie and the rostrum slightly 
infuscate. Head almost smooth, transversely depressed between the eyes ; rostrum arcuate, rather stout, 
a little longer than the prothorax, sparsely punctate, the antennew inserted at about the middle. Pro- 
thorax slightly broader than long, strongly constricted in front, and hollowed along the flanks beneath, 
so as to appear margined at the sides anteriorly, smooth. Sentellum very small. Elytra compressed at 
the sides, rapidly and obliquely narrowing from the rounded humeri; with a very fine sutural stria only, 
for the rest smooth. Beneath almost impunctate. Legs rather long and slender; femora punctate, 
sulcate and unarmed beneath ; anterior tibiee curved from the base, strongly retractile ; intermediate and 
posterior tibiz almost straight, the intermediate pair angulate near the base externally, the posterior 
pair angulate near the base and apex. 
Length 24, breadth 13 millim. (¢ ?) 
Hab. Mexico, Santa Lucrecia in Vera Cruz (Knab, in U.S. Nat. Mus.). 
One specimen, A remarkably distinct form allied to the Panama D. rubricatus and 
D. nigripes, with the legs long and rather slender, the anterior tibie not angulate at 
the base externally, the prothorax margined at the sides anteriorly, the sutural stria 
very fine and placed close to the suture, the body almost wholly rufescent. 
Diorymerus erythronotus (p. 220). 
To the localities given, add :—Mexico, Santa Lucrecia in Vera Cruz (Knad, in U.S. 
Nat. Mus.) ; Guatemaa, Trece Aguas (Schwarz & Barber, in U.S. Nat. Mus.). 
The Colombian D. levipennis, Kirsch, the type of which I have recently examined, 
is closely related to the present species, but differs from it in the sharply angulate 
anterior tibize and the obsoletely striate elytra. 
25. Diorymerus sulcatulus, n. n. 
Diorymerus sulcatus, anted, p. 222, t. 12. figg. 31, 31 a (nec Kirsch, 1875). 
The specific name sulcatus is preoccupied for a Peruvian insect, and a new one is 
therefore required for the species described in this work. | 
DIASTETHUS (p. 223). 
Diastethus falcatus (p. 228). 
To the Costa Rican locality given, add :—Ksparta (Anab, in U.S. Nat. Mus.: ¢ ). 
Two additional specimens (@ ) of this species have now been seen from Costa Rica, 
agreeing with a Colombian example of the same sex in the British Museum. They
