296 SEKRICOBNIA. 



the disc, feebly convex at the sides, sparsely punctured. Beneath thickly punctured ; prosternal sutures 

 excavate in front. 

 Length llf-13, breadth 3|-3| millim. ( c? ? .) 



Hab. Nicakagua, Chontales (Belt) ; Panama, Bugaba, Volcan de Chiriqui (Champion). 



Nine examples, three of which are males, one only being from Nicaragua. Like 

 Atractosomus cor ax, this insect varies a good deal in colour, the males being almost 

 black. S. ciliaticornis is not very closely allied to any of the species described by 

 Candeze, from all of which it may be known by the subconical thorax. We figure a 

 male from Chontales. 



SPILOMOPPHUS. 



Head with a prominent frontal carina ; apical joint of the maxillary palpi rounded-triangular ; eyes finely, but 

 distinctly facetted ; antennas with the joints from the third broad and triangular ; scutellum oval ; pro- 

 sternal sutures parallel behind, not excavate in front ; prosternum concave and abruptly declivous behind 

 the coxse, the process slightly flattened and subhorizontal, with an angular projection before the tip ; 

 mesosternum with the sides of the cavity vertical, and with a rounded elevation at the base immediately 

 in front of the metasternal process, which is produced anteriorly ; legs short ; posterior coxal plates 

 rapidly and obliquely narrowing outwards ; tarsi with joints 2 and 3 lamellate beneath ; claws simple. 



The single species referred to this genus has the meso- and metasternum formed 

 exactly as in Spilus ; but it differs from it in having the coxal plates undilated opposite 

 the point of insertion of the femora, the legs short, the prosternal sutures parallel 

 behind, the prosternum abruptly declivous behind the coxae, and the antennae with the 

 joints from the third broadly triangular. 



1. SpilomorpllUS ruMcollis. (Tab. XIII. figg. 12, $ ; 12 a, antenna.) 



Moderately elongate, rather broad, somewhat convex, shining ; black, the prothorax ferrugineo-testaceous, the 

 oral organs and frontal carina obscure ferruginous ; the legs piceous, with the knees and the tips of the 

 tarsi rufo-testaceous ; the under surface, the prothorax excepted, in great part black, the metasternal 

 process ferruginous ; above sparsely clothed with rather long hairs, which partake of the ground-colour, 

 beneath sparsely clothed with long yellowish-cinereous hairs. Head moderately convex, broadly flattened 

 in front, closely, rather coarsely punctate, tbe frontal carina prominent ; antennas short, scarcely reaching 

 beyond the humeri, joint 3 a little narrower than, and almost as long as, 4, 4-7 about as broad as long, 

 8-10 slightly longer than broad, 11 longer than 10. Prothorax transverse, moderately convex, the sides 

 slightly rounded and gradually converging from a little before the base ; the hind angles moderately pro- 

 duced, subparallel, rather blunt at tbe tip, not carinate above, limited internally by a short deep groove ; 

 the surface finely and rather closely punctate, canaliculate behind, and with shallow transverse basal 

 grooves. Scutellum tbickly punctured. Elytra three times the length of, and a little narrower than, 

 the prothorax, parallel to the middle and gradually narrowing beyond, the apices broadly, conjointly 

 rounded; finely punctate-striate ; the interstices almost flat, thickly punctured. Beneath finely and 

 somewhat thickly punctured, the propleurae more sparsely and more coarsely punctate. 



Length 10|, breadth (of elytra) 3 millim. ( $ .) 



Rah. Panama, Bugaba (Champion). 



One specimen. This insect somewhat resembles Anoplischius corallinicollis and 

 A. hemipyrrhus, Cand., but differs from them in the form of the meso- and meta- 

 sternum.
