28 SEEEICOENIA. 



The following species is only provisionally included. It has much the form of 

 S. neglecta, King, but is rather more parallel than that and almost all the species, and 

 has a very small scutellum. Having seen only a single specimen of the species, I refrain 

 at present from proposing a distinct genus for its reception. 



l. Sphenoptera purpurascens. (Tab. II. fig. 14.) 



Elongata, parallela, nitida, purpurascens ; capite creberrime viridi punctato, thorace minus crebre viridi 

 punctato, parum transverso, fere parallelo ; scutello parvo, transverso ; elytris tborace vix latioribus, postice 

 gradatim angustatis ad apicem sexspinosis, evidenter striato-punctatis, interstitiis secundo quartoque ad 

 apicem paulo elevatis. 



Long. 6| lin. 



Hab. Honduras (Brit. Mus.). 



The thorax has the lateral line sloping very obliquely downwards and obliterated 

 anteriorly. At the base of the thorax there are three punctiform impressions, one in 

 the middle and one on each side ; the base itself is straight in the middle and slightly 

 sinuate on each side; the posterior angles are right angles. The punctures forming 

 the lines on the elytra are not very close, but very distinct ; there are a few punctures 

 here and there on the interstices. The apex of each elytron has three spines ; of these 

 the second is a little removed from the sutural one and is a little more produced ; the 

 third is removed some distance from this, is more lateral, and very acute. The line 

 dividing the prosternum from the flanks of the prothorax is a straight line from its 

 commencement on the front margin to the coxal cavity. The metathoracic parapleura 

 are very narrow, parallel, and about three times as long as broad. The posterior coxal 

 plate is very broad internally, parallel for about half its length, then obliquely narrowed 

 externally. 



ACTENODES. 



Actenodes, Lacordaire, Gen. des Coleopteres, iv. p. 72 (1875). 



The species of this genus are chiefly confined to Central and South America. Two 

 occur in North America ; and it appears to me that Chrysobothris acuminipennis, Gory, 

 from Madagascar, and perhaps one or two other species of Chrysobothris from Africa, 

 would be better transferred to Actenodes.
