338 RHYNCHOPHORA. 
This species is not represented in our collection, but I have seen the type (¢) 
belonging to the Stockholm Museum. It is very like F. puneticollis, but wholly 
greenish-zeneous above; the rostrum and prothorax are more coarsely punctate; the 
seriate punctures on the elytra are coarser and more scattered, the interstices are more 
uneven, and the alternate ones (3, 5, 7, 9) are sharply costate on the apical declivity, 
and the legs are stouter and more rugose. ‘The antenne are inserted at one-third from 
the base of the rostrum, ‘The intermediate and hind tibie are straight on their outer 
edge ; the anterior pair strongly sinuate within. The tarsal claws are cleft and closely 
approximate, The anterior coxe are widely separated. 
26. Rhyssomatus puncticollis, sp. n. 
Oval, convex, shining, eneo-piceous, the elytra rufescent, the prothorax and legs with a brassy lustre, almost 
glabrous. Head closely, minutely punctate, faintly foveate above the eyes, which are contiguous ; rostrum 
stout, becoming a little thicker towards the base, scarcely as long as the prothorax, feebly curved, closely, - 
finely punctate, the antentie inserted near the base. Prothorax broader than long, slightly rounded 
at the sides, narrowing from the base, constricted on each side in front, thickly punctate, the punctuation 
becoming coarser on the flanks, the dise with a narrow smooth space along the middle. Elytra forming 
an almost continuous outline with the prothorax; coarsely and deeply seriate-punctate, the interstices 
flat and almost smooth, 3 very sharply, and 4-9 more feebly, costate on the apical declivity. Anterior 
coxee widely separated. Legs short, rather slender; anterior and intermediate tibie straight on their 
outer edge; tarsal claws approximate. 
Length 33, breadth 2 millim. (? 9.) 
Hab. Mexico, Teapa in Tabasco (H. Hf. Smith). 
One specimen. Smaller than &. nitidus, the legs and prothorax with an eneous 
lustre, the latter more coarsely punctate on the disc, the third elytral interstice very 
sharply, and the others (the second excepted) more feebly, costate on the apical 
declivity. The tarsal claws are so closely approximate that the inner tooth is not 
easily seen. Its differences from 2. viridipes are noted above. 
27. Rhyssomatus nitidus, sp.n. (Tab. XVII. figg. 30, 30a, 2; 80%, interm. 
tibia.) 
Oval, convex, shining, rufo-piceous, the elytra ferruginous, almost glabrous. Head minutely punctate, 
obsoletely foveate above the eyes, which are separated by a thin lamella only; rostrum stout, almost 
straight, about as long as the head and prothorax, sparsely punctate throughout, without trace of carina, 
the antenne inserted near the base, the scrobes, however, extending forwards to beyond the middle. 
Prothorax broader than long, conical, slightly constricted in front, strongly bisinuate at the base; some- 
what closely, minutely punctate, the punctuation becoming much coarser at the sides, the disc with a 
smooth median line. Elytra much wider than the prothorax, narrowing from the rounded humeri, which 
in front form an almost continuous outline with the sides of the prothorax ; coarsely and deeply seriate- 
punctate, the punctures rounded and each placed in a larger and darker spot showing through from 
beneath, the interstices flat, becoming convex on the apical declivity, and very sparsely, minutely punctate. 
Anterior coxe widely separated. Legs rather slender; anterior tibie strongly sinuate within, the 
intermediate and posterior pairs straight on their outer edge; tarsal claws subapproximate. 
Length 5, breadth 3 millim. ( 9.) oe
