pnlpi will rcndily separate it. It appear.s also to be allied to Crntro- 

 ioma, but the angulated joints of tbe maxillary palpi sepai'ate it 

 therefrom. 



Tetracis complex, n. sp. 



Rufescens, nifidus, j)rot]iorace suhlransvcrso ; eli/lris stria suturnli, 

 striaque discoidnli inferp'o, hasi profunde impressis foveo latisque ; ah- 

 doiiiine segmenfls 1 ef 2 snpra et infra hasi dense rjlanduloso pubescent ihus. 



Long. Corp. ultra 2 mm. 



AiitoiinsD much longer tliau head and tliorax, rather stout, the basal joint nearly 

 as long as the two following joints together, a little stouter than the second joint ; 

 second joint distinctly longer than the third, but scarcely thicker than it; joints 

 four to eight not differing from one another ; joints nine and ten elongate, a little 

 stouter than the preceding joints, each longer than broad ; eleventh joint elongate, 

 distinctly stouter than the tenth joint, and as long as the ninth and tenth together. 

 Head, with the vertex elevated but short, -with the impressions very obsolete. Thorax 

 narrower than the elytra, but distinctly broader than the head and eyes, not so long 

 as broad, at the base in the middle, with a dense patch of glandular pubescence, and 

 at the hind angles with similar pubescence extending downwards as far as the coxfc. 

 Elytra longer than the thorax, a little narrowed at the shoulders. 



The specimen described is, no doubt, a male : it has the metasternum longitu- 

 dinally sulcata. The antenna; of the female may very probably differ from the above 

 description. 



A single specimen of this highly interesting species was sent me 

 from Tangicrs, by M. Olces, as being the Ctenistes integricoUis of 

 Fairmaire. Fairmaire has, however, figured both the G. integricoJlis 

 and its magnified palpus, and these figures leave no doubt that it is 

 a very different insect from the one here described. 



PsELAPnirs Saulcti, ii. sp. 



Castaneus, minus nitidus ; palpis maxillarihus articulo ultimo valde 

 elon(/ato, parte apicali ahrupte dilatata, hreviter ovaJi ; anfrnnis articulo 

 nono precedente (infemina?) latioresed haudduplolongiore ; prothorace

Long. Corp. vix 2 mm. 



Dark reddit-h-chestnut, with the head and thorax narrow, and the after-body 

 very broad ; on the upper-side the head, thorax, and elytra are sub-opaque, the 

 liind body shining ; the maxillary palpi are very elongate, the dilated apical portion 

 of their terminal joint is only about one-fourth of the length of the extremely slender 

 basal portion ; the ninth joint of the antcnnse is not much longer than broad. 



This highly interesting insect is apparently most nearly allied to 

 the P. Diecli, Saulcv, and its genera* form resembles greatly the
