Tryponceus cornifrons, sp. n. 



Elongatus, cylindricus, niger, nitidus ; rostro apice acuminato, 

 bisulcato ; froute in medio conspicue tubereulafca ; pronoto antiee 

 depresso ; elytris rufo-maculatis ; propygidio pygidioque vix dense 

 punctatis ; prosterno mesosternoquc bisulcatis ; metasterno longi-

L. 5i mill. 



Elongate, cylindrical, parallel laterally, black and shining; 

 the head, rostrum acuminate and slightly reflexed at the apex, 

 somewhat trigular and bisulcate on either side of a median 

 carina, on the vertex is a large and conspicuous dentiform 

 tubercle, the ocular tubercles are rather small and obtuse, 

 behind the front tubercle are large shallow somewhat irregular 

 punctures ; the thorax behind the head is rounded off, 

 depressed and punctured, the punctures are larger than those 

 on the head but otherwise are similarly shallow and irregular, 

 the other parts of the thorax are more clearly punctured but not 

 thickly, especially near the scutellum, where the points are 

 finer ; the elytra are finely and rather sparingly punctulate, 

 with a large lobe-shaped red spot, the spot does not touch the 

 base and is rather more narrowly divided at the scutellum ; 

 the propygidium and pygidium are rather densely punctate, 

 the latter being pilose and obtuse at the apex ; the presternum, 

 the keel has the outline of an elongate triangle and a marginal 

 stria which is not continued at the base ; the mesosternum is 

 "obtuse anteriorly with two deep lateral sulci, the keel has a 

 few scattered punctures ; the metasternum has two short 

 sinuous strise which touch the anterior edge behind the middle 

 of the mesosternal keel, there are no lateral striae, but the 

 surface has large and clear punctures, especially down the 

 median area ; the anterior tibias are 4-dentate and the tooth 

 on the inner edge is very long and conspicuous. 



This species may be placed near T. pictus^ Mars., but it is 

 parallel at the sides and the rostrum is formed like that of 

 T, spim'ffer, Mars. I have not seen the female.
