This is another common and variable species. In many speci- 

 mens the 3^ellow elytral stripe does not turn up to join the suture; 

 sometimes the stripe is bare, sometimes covered with yellowish 

 pubescence, which occasionally extends right across; the two 

 connected stripes often appear as a cleanly cut W, more frequently 

 the outer edges are jagged or rounded; the spots near the apex 

 of each elytron are often joined, appearing as a narrow crescent, 

 which has its convex side towards the apex, sometimes as a single 

 moderatel}^ large spot, and — rather rarely — all are united to form 

 a transverse fascia; the yellowish pubescence frequently extends 

 along the suture from the base to in line with the apical spots. 

 The prothoracic macula? are often distinct, and equally as often 

 entirely obsolete. I have a specimen in which the elytral pubes- 

 cence ajDpears as four distinct maculae. The size is somewhat 

 ^'ariable.

MORDELLA PULCHRA, n.Sp. 



Black; abdomen bright red, aculeus piceous-black at apex; four 

 anterior coxie, femora and the palpi brownish-testaceous, tibite 

 and tarsi darker; antennae reddish-piceous, at the ba.se testaceous; 

 spurs to posterior tibiae testaceous. Head and prothorax not 

 very densely clothed with somewhat silvery pubescence, on the 

 latter three indistinct black macula?, the largest extending from 

 near the base to near the apex, the lateral ones ol^lique, almost 

 touching the central. Elytra with silvery pubescence as follows : 

 between the suture and sides an elongate somewhat triangular 

 spot, narrowly joined to the suture at the base; on the shoulders 

 a rather indistinct spot, which ca^n hardly be separated from the 

 inner one; two transverse zigzag fasciae, one slightly before the 

 middle, the other before the apex, the one in the middle very 

 narrow at the sides, broadest at the suture, from the sides (on its 

 anterior edge) running obliquely backwards, then up, down, up, 

 and then semicircularly to the suture, its posterior edge triangular
