E cfafoinin i pli /la, n . g . 



The species of tliis genus aie nearer tlie nurinal // isteridae than 

 any of the others. The prothm-ax is wide and \vith(uit raised mar- 

 gins. The elytra are transversely impressed behind the base, and 

 the shoulders are not cleft, and are without special clothing. The- 

 legs are short, wide, and fitted into grooves. 



The two know*n species occur in nests of Ectafoiinna inttdUirinn. 



PJieidoli pliiJa, n.g. 



The sjjecies of this genus are all small. The prothorax is strongly 

 raised in front, with the raised portions overhanging the head. 

 The elytra are not depressed immediately behind the scutellar 

 region, but there is a depression close to each shoulder; there is 

 an oblique incision at each shoulder, but the shoulders themselves 

 are not raised above the general level, although clothed internally. 

 All the legs are fitted into grooves. 



The host of sfernalis is unknown, but all the other species have 

 been taken from nests of various species of Pheidole. 



I'heidoliphila miniifa, n.sp. (Plate XXII., Fig. 1.) 

 Reddisli-castaneous, prothorax somewhat darker. Clotlied with 

 golden setae within each shoulder, elsewhei'e almost or quite glab- 

 rous. 



Head small, vertical and feebly concave. Antennae with basal 

 joint large, subtriangular and rather wide. Prothorax about thrice 

 as wide as the lateral length, subopaque, smooth and indistinctly 

 punctate; median three-fourths of apex, appearing as a shining, 

 regularly curved, and moderately elevated ridge, each side of which 

 is marked by a subtriangular notch. Elytra subquadrate, widest 

 close to base, with a distinct depression within each shoulder; each 

 side at base appearing as a wide obtuse projection, which is con- 

 spicuously elevated at the depression, but not elevated above the 

 general level, and obliquely cut off at the outer base; disc regularly 

 convex, with dense and small, but clearly defined punctures. 

 Pygidium and propygidium w-ith minute punctures. Prostermim, 

 with a deep, wide and almost parallel-sided groove, extending 

 almost its entire length. Metasternum with a feeble median line, 

 and with minute, but clearly defined punctures, similar puncturea 

 in l)asal segment of abdomen. Legs rather short, tibiae distinctly 

 flanged, the flanges increasing in width from apex to near base^ 

 and then more or less obliquely cut off. Length, H mm
