fortiter piiuctatis ; abdoinine l)asi parce, apice crebre, punctato ; tarsis 

 anterioi'iljus latroque sexii simpliciljus : maris segmento ultimo ventrali aj)ice 

 tantum leviter emaiginato. Long. corp. 10-12 mm. 



The five examples befoie me of tliis species are remarkal)le from the 

 \'ariation in the numljer of the thoracic piinctmes. These may be either 3, 



4, ()!■ 5 in each series ; thus it is somewhat unceitain to which of Eiichson's 

 groups of species it should be referred, but pi'obaldy it may jn-ove to lielong 

 to group 4. Mr. Whymper informs me that this species is rather aliundant 

 in the interior of Ecuador. 



5. P. ilivisus, n. sp. (Group 5, Erichson). 



Hah. Machachi (9-10,000 feet). One exampk-. 



Niger, nitidus, clytris la^te flavis, basi violaceo ; antenni.s parum cldngatis, 

 articulis quinto ad decimum tnnisvei'sis ; capite ol)long(:), parce fortiter punc- 

 tato ; tliorace nitidissimo laterilms subrectis, angulis anteiioribus subrotun- 

 datis, ntrinque serie discoidali punctorum quinque impresso ; elytris parum 

 profunde, ,sed hand subtiliter punctatis ; abdomine nitidulo, parce jiunctato ; 

 tarsis iiifescentibus. ^las incognitus ; feminse tarsis anterioribus simplicibus. 

 Long. corp. circiter 1 2 mm. 



G. Sterculia impressvpcnnis, n. sp. 



Hah. Nanegal (3-4000 feet). Three examples. 



Cyaneo-violaceus ; antennis sat elongatis, scapo giacili ; capite lutioi'e, 

 densissime fortiter punctato ; prothorace angusto, posterius parum latiore, 

 crebrius fortiter punctato, posterius in medio Isevigato, ad latera parum 

 impresso ; elytris crebre obsolete punctatis, versus latera anterius leviter, ad 

 angulos posteriores profunde, impressis ; capite subtus fortiter sat crebi'e 

 punctato. Long. corp. 21 mm. 



The tliree examples vary somewhat in colour and size, and a good deal 

 in the length of the mandil)les, but agree in the thoracic structure and 

 punctuation. 



7. Cryptohium, sp. '( 



Hah. Pacific slopes (7-8000 feet). A single female exampk' in a muti- 

 lated condition, unsuitable for description.

 elytris vii'idis ; antennis tenuil)us sat elongatis ; capite parum lato, sat crebre 

 hand fortiter punctato ; thorace oblongo-ovali, lateribus obsolete punctatis ;
