PIAGETIA. 211 



described. There is in the collection of the British Maseuin a 

 sixth uudescribed form from Natal, received in the Museum in 

 1855, from Dr. Grueinzius ; and as one specimen, a female, is 

 pinned above a cricket, as if in the act of carr5'ing it, I presume it 

 was so engaged at the time of capture. It is highly probable 

 that all the species of this genus are, like the rest of the closely 

 allied Larrid genera, predatory on Orthoptera. 



Key to the Sjjecies. 



a. Clypeus ( $ ) with a medial carina, trans- 



verse or incised at apex ; antennae entirely 



red P. nijiconm, p. 211. 



b. Clypeus ( $ ) anteriorly with two teeth ; 



scape of antennae only red P. fasciatipennis, p. 211. 



402. Piagetia ruflcornis, Cam. Mem. Manch. L. Ph. Sue. (4) ii, 1S89, 



p. 133, $. 



§ . Head, thorax, and abdomen opaque, the head and thorax 

 very minutely and closely punctured, the surface of the abdomen 

 above aciculate ; clypeus broad, transverse anteriorly, the sides 

 oblique, the disc having a medial short vertical carina ; the front 

 with a medial vertical furrow, and a broader curved shallow 

 furrow on each side ; median segment with an indistinct carina 

 down the middle, the apex of the segment strongly narrowed and 

 truncate ; an oval, rather deep fovea on the posterior face of the 

 truncation ; abdomen about the length of the thorax ; the pygidial 

 area bare, distantly punctured. Black ; the base of the mandibles, 

 the clypeus, antennae, pronotum, sides of the mesonotum anteriorly, 

 sides and apex of the median segment broadly, the legs, and 

 petiole of the abdomen dull reddish ; the apical two joints of the 

 antennae, the coxa? of all the legs, and the femora and tibiae 

 of the intermediate and posterior pair more or less marked 

 with fuscous black ; the clypeus and front and base of the 

 median segment with dense silvery pile ; wings hyaline and 

 iridescent, with a fuscous subapical fascia from the base of the 

 radial to the apex of the 2nd discoidal cell ; nervures and tegulre 

 testaceous. 



Hah. Calcutta; Poena. $. Length 9-10; e.vp. 16-18 mm. 

 (S unknown. 



403. Piagetia fasciatipennis, Cam. Mem. Manch. L. Ph. Sac. (4), ii, 



1880, p. 16, cJ. 



2 . Closely allied to and resembling P. rujicornh. Cam . ; differs 

 in the clypeus having two strong teeth anteriorly, in the median 

 segment being broader at the apex, and the femoral tooth, which 

 in rujtcornis forms a mere tubercle at the base below of the 

 posterior femora, being developed into a small but distinctly
