28 Mv. 11. Scott on Corylopliidae/V(?m the 



organs cnn be seen niuler the partly opened elytra of the 

 siiiiile ? , but actual dissection and search tor minute 

 vestinri;il win.2;s is prevented by the necessity of preservinji: 

 the specimen intact ; the two ^ have ample wings, folded 

 under the elytra ; one of these or<>;ans is mounted in balsam, 

 but I have failed to unfold it completely, so cannot state its 

 proportions to the elytron accurately ; it is, however, con- 

 siderably longer than the elytron (see p. 4). Metnsternum 

 (J with a marked median longitudinal impression broadening 

 behind, on the ])osterior f of its length ; surface of the meta- 

 sternum almost impunctate, with pale short hairs, closer in 

 the impression, very scanty at the sides ; in the $ the meta- 

 sternum is convex and glabrous in the middle. F(rst ahdo- 

 minal segment : c^ , with no impression, but with a median 

 group of a few short hairs, on either side of which it is bare, 

 but has a few other hairs near the lateral margins ; ? , no 

 median group of h;iirs. U"he other segments bear scanty pale 

 pubescence. 



This species is quite distinct from any I have seen. The 

 form most closely resembling it superticially is li.hr evicornis, 

 Matth. (West Indies). A j of this, now before me,. is the 

 same size, but more attenuated behind ; the reticulation of its 

 thorax is slightly less marked, while irs elytial punctures are 

 a little stronger ; and it diflfers decidedly in the nature of its 

 (J ventral impressions {vide supra, p. 26).

 (PI. IV. tigs. 40, 41 ; PI. V. figs. 42-44.) 



Tlie material includes at least two, possibly three, species 

 of this genus : a new and very distinct form from Rangoon ; 

 a single J from the Seychelles, referred to a species known 

 from S. America and W. Indies ; and a single indeterminable 

 specimen from Rangoon, possibly the ? of the preceding, 

 possibly distinct. 



Diverging Slrice on Meias/ernuni. — I have found in the 

 literature no mention of diverging striaj or lines on the meta- 

 sternum, curving round behind tlie middle coxse (tig. 41, I.) ; 

 yet they are ])resent in a number of species. Tiiey recall 

 the diverfring striae found in a similar position in Acritus 

 and other Histeridse, but in these there is a second pair of 

 diverging striae behind the hind coxse on the first abdominal
