A widely distributed genus including a few Palearctic species, and also represented 
in North America, the Hawaiian Islands, and Ceylon *. Buchanan White’s genus 
Ploiariodes was based upon one of those forms with the pronotum tuberculate in the 
centre at the base, and the single Central-American representative belongs to that 
group. 
1. Ploiariodes armata, n. sp. (Tab. X. figg. 9, 9a; 9 6, anterior leg.) 
Very slender, sparsely pubescent, opaque; ochraceous, mottled with fuscous, the body beneath and the 
abdomen, the connexivum excepted, blackish or fuscous; the pronotum with two ochraceous or whitish 
vittee on the disc of the posterior lobe, the sinuous lateral carinze white, the basal elevation fuscous or 
blackish ; the elytra reticulated with white, the interspaces more or less fuscous, the apical third with 
some more or less distinct reddish-brown markings ; the legs, rostrum, and antennw whitish or whitish- 
ochraceous, closely speckled or annulated with nigro-fuscous, the anterior legs sometimes more broadly 
annulated than the others. Head with a deep transverse groove between the eyes, the latter large and 
prominent ; antenne very elongate, with joints 1 and 2 subequal in length, 2 nearly twice as long as 
3 and 4 united, 4 about one-third the length of 8. Pronotum with a short, abrupt, subangular, cariniform 
elevation on the middle of the disc just before the posterior margin. Scutellum, post-scutellum, and base 
of the abdomen each with a long semi-erect spine. Anterior femora with a row of short fine teeth along 
their lower edge. 
Length (to apex of the elytra) 5-6 millim. 
Hab. Guatemaa, Capetillo (Champion); Panama, Bugaba (Champion). 
Three specimens, one of which has lost its head, this example having all the legs 
broadly annulated with fuscous. P. armata is allied to the Palearctic P. berensprungi, 
Dohrn, and P. brevispina, Puton, but it has much larger eyes, &c. 
LUTEVOPSIS, n. gen. 
Head about as long asthe anterior lobe of the pronotum, parallel in front, convex and obliquely narrowing 
behind, without frontal spine, the eyes prominent ; rostrum with the two basal joints subequal in length ; 
antenne with joints 1 and 2 exceedingly elongate. Pronotum elongate, divided into two parts of nearly 
equal length, the anterior lobe cylindrical, somewhat arched, and gradually widening forwards, the 
posterior lobe convex, broader, and covering the mesothorax. Meso- and metathorax short, subequal in 
length, together not longer than the pronotum. Scutellum unarmed. Elytra extending to near the apex 
of the abdomen. Abdomen elongate, narrow at the base, subovate. Anterior coxe elongate, about as - 
long as the tibia. Anterior trochanters unarmed. Anterior femora long and subcylindrical, slightly 
longer than the tibia and tarsus united, armed with a series of spines, which extend from the base to 
beyond the middle. Anterior tibie very finely denticulate within. Anterior tarsi short, a little longer 
* The P. oculata of Mr. Kirby’s list (Journ, Linn. Soc., Zool. xxiv. p. 123) is a Berytid, near Metacanthus.
