DOLICHOBARIS.—ODONTOBARIS. 419 
coxee less approximate; the first ventral segment shallowly sulcate down the middle in the ¢, the 
anterior tibie with a long apical uncus in this sex. 
Length 2;4-3, breadth 1-14 millim. (¢ @.) 
Hab. Mexico, Atoyac in Vera Cruz (H. H. Smith); Guatemata, Las Mercedes, 
Chiacam, Cahabon (Champion), Trece Aguas in Alta Vera Paz (Schwarz and Barber, 
in U.S. Nat. Mus.) ; Nicaragua, Managua (Solari). 
Nine specimens. ‘This insect might be taken fora small Limnodaris, near L. pygmea, 
if the exposed pygidium, &c., were not taken into account. 
ODONTOBARIS, gen. nov. 
Mandibles pointed, almost straight on their inner edge, bidentate on their lower edge externally (fig. 31 a): 
rostrum straight, flat, rather slender, widened in their outer half, the scrobes obliquely descending and 
sinuous beneath, the antenne inserted at the middle, the scape nearly reaching the eyes, the funiculus 
6-jointed, joint 2 a little shorter than 1, obconic, the club short and stout, globose-ovate; head small, 
the eyes transverse, large; prothorax subquadrate, feebly sinuate at the base; scutellum very small, 
transverse, hollowed in front; elytra oblong; pygidium exposed, transverse ; prosternum with the ante- 
coxal portion convex and unimpressed, the short flattened basal process rounded posteriorly and feebly 
sulcate down the middle; mesosternum depressed, connate with the metasternum, the epimera large and 
angularly ascending; anterior coxw separated by considerably less than their own width; ventral 
segments 2 and 5 equal in length, 1 and 2 connate; femora short, compressed, strongly clavate, unarmed ; 
anterior tibie deeply excavate at the apex externally, the excavation limited by a sharp tooth; tarsi 
rather slender, the claws free; body elongate, rather broad, flattened above. 
Type, O. planirostris. 
The Mexican insect forming the type of this genus is the first described Barid with 
a 6-jointed funiculus, and it also has the mandibles, rostrum, &c. peculiarly formed. 
The mandibular structure is suggestive of that of Plocamus. ‘There is an allied unnamed 
form from Brazil, placed under the genus Cedetes, Schonh., in the British Museum *. 
1. Odontobaris planirostris, sp.n. (Tab. XX. figg. 31, 31a, .) 
Shining, black, the tip of the rostrum, antenna, knees, tibiz, and humeri more or less ferruginous; the upper 
surface clothed with scattered, fine, hair-like, whitish scales, which are uniseriately arranged along each 
elytral interstice, the vestiture of the under surface a little longer, coarser, and closer, the antennal 
funiculus and club setose. Head finely punctate; rostrum nearly as long as the head and prothorax, 
sparsely, finely punctate. Prothorax transverse, narrow and feebly constricted in front, the sides 
rounded anteriorly and parallel behind; closely punctate. Elytra long, slightly wider than the prothorax, 
very gradually narrowing from the obtuse humeri; sharply crenate-striate, the interstices rather broad, 
flat, irregularly uniseriate-punctate. Pygidium densely punctate. Beneath coarsely and densely, the 
abdomen more sparsely, punctate. 
Length 54, breadth 23 millim. (2 ?) 
Hab. Mexico, Cerro de Plumas + (fHége). 
One specimen, perhaps slightly immature. 
* This is a narrow, elongate, polished form, rufous in colour, with a black spot on each elytron towards 
the apex. 
+ The name of this locality, as given by the late F. Hoge, and quoted throughout this work, is probably a 
mistake for ‘“‘ Cerro de Palmas,” in the State of Vera Cruz.
