344 Mr. D. Slmrp's ContrUmtioyis to the 



Fern. : al)(l(Jiiiinc scgmento 7° ventrali producto, apice 

 excisione triaiigulari magna, lobis lateralibus acumiiiatls, 

 leviter rccurvis. 



Antciinai rather stout (for this gemis), ahiiost whito, 

 rather short; 8rd joint sHghtly longer than 2nd; lOth 

 joint about as long as but distinctly stouter than the 9th, 

 11th a good deal stouter and longer than the 10th, acu- 

 minate at the extremity. Palpi pale yellow, last joint 

 not very large. Head very shoi't, broad, almost as broad 

 as the thorax; the vertical line fine, very slightly deflexed 

 in the middle, contiguous at the sides with the hind margin 

 of the eyes, slightly interrupted in the middle ; the surface 

 is coarsely and rather closely punctured. Thorax a good 

 deal broader than long, slightly narrower than the elytra, 

 the base and hind angles rounded; the surface rather 

 coarsely and closely ])unctured, so that the smooth spaces 

 are almost al)sent. Elytra not quite one and a half times 

 the length of the thorax, rather closely and only mode- 

 rately coarsely punctured; the punctures near the scutcllum 

 dense, at the extremity distinctly more sparing. Hind 

 body broad, darker in colour than the front parts ; the two 

 apical segments without imbricate jjunctures. Legs pale 

 yellow, rather stout and short. 



In the female the ventral plate of the 7th segment of 

 the hind body is produced and has a large deep notch in 

 its apical portion ; the sides of this plate come to a point 

 at their termination, and are a little curved upwards. 



Tapajos ; a single specimen. 



AVhen I first examined it, I supposed this individual to 

 be a male ; but as ou dissection I find no trace of the 

 ajdeagus, I conclude, with something like certainty, that 

 it is a female. 



6. Palnminus breviceps, n. sp. Castaneo-testaceus, an- 

 tennis, palpis, pedibusque pallide testaceis ; capite brevi ; 

 prothorace transverso, basi sub-truncato. Long. corp. 

 21 lin. 



ISIas latet. 



Fem. : abdomine segmento 7° ventrali apice medio ex- 

 cisione sat magna. 



A rather slender species. The tAvo basal joints of the 

 antennae are pale yellow, as are, no doubt, also the others, 

 though they are broken off in the specimen described. 

 The palpi are pale yellow, with the terminal joint small.
