Promecops lineigera nov. sp. 



P. ovata, silacea, squamis pallidioribus, lineatim albido-notata; 

 rostrum brève, in medio canaliculatum ; antennae ferrugineae ; 

 funiculus articulis longitudine sub-sequalibus; prothorax subcylin- 

 dricus, sparse punctatus; scutellum rotundatum; elytra substriato- 

 punctata, punctis squama alba in medio instructis, linea obliqua 

 albida ab liuraeris — ad satiiram interrupta — altéra, minus obli- 

 qua, pone médium, notata, apiceque pallidiora; corpus infra pedes- 

 que silacei, squamulis margaritaceis sat laxe vestiti. Long. 4""». 



This species comes very near P. arcuata, the type of the genus, a 

 variable species as to colour, which bas setiilose elytra, the latéral 

 margin greenish-silvery, and the body beneath pitchy with bright 

 green scales. Lacordaire would confine the genus to those species 

 like the présent, whose claws are united at the base, but in his 

 generic description founded on such species, he inadvertedly 

 describes the claws as free. 



Arrhetus nov. gen. 



Oculi inferi, rotundati, tenuiter granulati. Rostrum modice 

 elongatum, in medio anguste cylindricum ; scrobes latérales. 

 Antennae prœmediana^; scapus arciiatus; articulo basali funiculi 

 longiore, ceteris breviter cylindricis ; clava ovata. Prothorax 

 ampliatus, basi truncatus, lobis ocularibus ciliatis. Scutellum 

 distinctum. Elytra prothorace haud latiora, humeris rotundatis. 

 Propectus integrum; coxse antice separatse. Mtsosternum brève. 

 Abdomen segmentis duobus basalibus ampliatis ; sutura prima 

 incurvata. Pedes robusti; femora dente minute instructa; tibia3 

 apice bicalcaratae ; tarsi lati, unguiculis liberis. 



This genus is allied to Strongijlopterus which has a well-marked 

 pectoral canal, more slender legs, narrower tarsi, etc. In Nettarhi- 

 nus, a neighbouring genus, the canal is absent, as in Ârrlidtis. 



Arrhetus Volxemi nov. sp. 



A. ovatus, niger obscurus, supra nitide granulatus; caput 

 tenuiter punctatum ; inter oculos planatum et plus fortiter punc- 

 tatum; rostrum nitidum, subtiliter punctatum, apice dilatum ; 

 antennse picese, funiculus validiusculus, clava tomentosa; protho- 

 rax subtransversus, ad latera rotundatus, basi vix angustior, 

 granulis approximatis instructus; elytra in medio paulo latiora, 

 apice late rotundata, granulis numerosis oblongis subseriatim 

 ordinatis; corpus infra, femora, tibiseque subnitidae, squamis 

 parvis sparse indutae; tarsi albo-pilosi. Long. 12""".
