 Two UNPUBLISHED VARIETIES. — SpJicBrhuji ovnk var. tvnnslnccns, 

 Wigglesworth : Much brighter than the type, shining and translucent, 

 very pale slate inclining to yellow at the edge. The largest measured 

 15 mm ; a type example found Avith them 1 mm.pnore. Examples of 

 the the var. and type have been sent me by Mr. R. Wigglesworth, 

 who procured them from the canal at Clayton-le-Moors. 



Uiuo pictorum var luajov : \'ery large, 4 to 5 ins. in breadth, heavy, 

 strongly ridged in the line of growth. My largest example measures 

 5 ins. '^127 mm.) and weighs just 1,000 grains (64.7 grammes.) Found 

 in the lake at Ossington, near Xewark, where they occurred in large 

 numbers, forming the bulk of those exposed on the drawing off of the 

 ^v^ater for cleaning out purposes. I am aware that large examples of 

 this species have been reported from time to time, l)ut I believe this is 

 the only instance know^n in which they have been found largely ex- 

 ceeding in nuniber those of the ordinary size. — W. A. Gain. 



THE SECONDARY SEXUAL CHARACTERS OF 

 THE BRITISH COLEOPTERA. 



BY JOHN W. ELLIS, M.H. (vic), F.E.S. 

 (Cnntimied frcvi p. 212). 



Of the secondary sexual cliaracters of the Coleoptera those presented 

 by the feet (tarsi) are perhaps of the greatest service to the systematist, 

 since the variations m their structure liave a greater tendency to run 

 through genera and even families, than ha\-e any of the previously 

 mentioned peculiarities of structure. The most common of the sexual 

 variations is a widening of one or more joints m some, or all of the 

 feet, a character always indicative of the male sex. Some species 

 have only the basal joint of the front feet dilated in the male, such as 

 all the species of Notophilus and Noterus ; most species of Hypocyptus : 

 {Corttcaria crenulcita, denticulata , etc . ) , Trichms fasciatus, some Ciyptoce]jhali 

 (minutus, piLsilhis, labiatiisj, and most species of Haltica. Many of the 

 Phytophaga, such as botli species of Gastrophysa, all Prasociiris, 

 Phratnra vulgatissima, Phyliohvotica quadriniaculata, Adiiuonia capra-a and
