 near base with a deep fovea, Elytra lightly punctured, more thickly so near 

 posterior angles, with short pubescence ; sub-qiiadrate, with the sides slightly 

 roiinded at shoulders ; suture depressed, and with a rather conspicuous stria ; 

 on the apical margin near posterior angles a tuft of hairs. Abdomen much 

 longer and a little wider than the elytra, very smooth and shining, with the 

 sides well rounded anteriorly, depressed at base, with golden pubescence at basal 

 angles, very convex to apex. Legs rather long, with tibiae narrower at base ;

This species is allied to F. goiinellei EafEr. and F. brasUiensis Westw. 

 It differs from F. gouneUei in its larger size, the deeper prothoracic 

 fovea, and the lightly punctured elytra, which are not tri-impressed at 

 the base, and have the apical margins tufted, F. brasilierisis has three 

 f oveae on the prothorax and two impressions on the head, the sides of 

 abdomen rounded further from the base, and is also a larger insect. 



Articerodes horneensis sp.n. (Plate XIX, figs. 3, 3a, h). 



c? . Castaneous, shining, sub-parallel-sided. Head sub-cylindrical, short,

 little broader than apex of prothorax ; eyes rather large, placed a little behind 

 middle. Antennae four-jointed, shorter than head; 1st joint hidden, 2nd and 

 3rd about equal, short and transverse, 4th large, cylindrical, narrow at base, 

 truncate at apex, with short pubescence. Prothorax about as broad as long, 

 widest at base, slightly rounded, narrowing to apex, sides margined and with 

 three setae, angled at base, covered with small, shallow punctures. Elytra 

 slightly broader than long, broader than base of thorax, with rather dense 

 golden pubescence, shoulders well marked, with a distinct fold ; apical margin 

 with a pointed projection in middle of each elytron. Abdomen : first dorsal 

 segment very large, convex posteriorly, smooth, and shining, about as long as 

 elytra, with sides a little rounded to apex, truncate beliind, sides well margined, 

 each Avith three tufts of golden hairs ; base divided into three rather deep 

 excavations by two tufts beneath the elytral projections. Legs short and 

 stout ; the intermediate femora much dilated, and having below a long curved 

 spur (see fig. 3b), the intermediate tibiae armed with a small s^jur towards 

 apex, and the posterior trochanters armed with a spine, and the tibiae with a
