PENTILIA.— CEYPTOGNATHA. 181 



2. Pentilia (?) convexa. (Tab. XI. fig. l.) 



Breviter ovata, valde convexa, nigra, nitida ; capite, prothoracis margine antico et angulis anterioribus tenuiter, 

 pedidus abdomineque flavis, prothorace elytrorumque basi seneo-micantibus, subtiliter crebre punctatis. 

 Long. 4 millim. $ . 



Mas capite protboracisque margine antico flavis. 



Hab. Panama, Bugaba (Champion). 



Bluish black above, the thorax and base of the elytra brassy ; head, legs, and 

 abdomen, and the sides of the thorax nearly as far as the hind angles, and also the 

 front margin, very narrowly, yellow. Elytra very convex, and viewed laterally rather 

 gibbous, the humeral callus distinct, very finely but thickly and distinctly punctured. 

 The tibiae are compressed on the outer side, and a little expanded towards their base. 



This insect, of which we have only obtained a single male example, is twice as large 

 as Pentilia egena, and is more convex than that species ; the base of the thorax is also 

 less V-shaped, the bases of the elytra being less inclined. 1 cannot at present associate 

 any specimens from Bugaba with P. convexa as females, the only example of that sex 

 from that locality being apparently referable to P. egena, the male of which, in addition 

 to the differences pointed out above, has the front angles of the thorax broadly yellow 

 and more rounded. 



3. Pentilia castanea. 



Pentilia castanea, Muls. Spec. Col. Trim, secur., App. p. 1036 x j Crotch, Rev. Coccin. p. 199 2 . 



Hab. Mexico 2 . — South America x 2 . 



The specimen referred to by Crotch 2 is in his collection, but it is without precise 

 indication of the locality. The Mexican habitat needs confirmation. 



4. Pentilia discors. 



Atra, nitida ; capite, protborace, abdomine pedibusque albido-flavis, corpore subtns nigro-piceo. 

 Mas ? elytris disco apiceque indistincte sanguineo notatis, protborace toto flavo. 

 Femina ? protboracis dimidio basali nigro. Long. 2 millim. 



Hab. Guatemala, Eio Maria Linda 500 feet (Champion). 



This little species is of a broadly ovate form, almost orbiculate ; it is very finely, but 

 distinctly punctate, and has the humeral callus rather distinct and the lateral margins 

 a little expanded. 



We have received only one specimen of each of the supposed sexes; they were both 

 met with at the same time and place, and, though differing in colour, I have little 

 doubt they are correctly associated as one species.
