Several very closely allied sjiecies of Cu/aspo/di's from the Kast 

 have ])een doscrihed , all jjossessing a strongly developed tooth 

 at the j)Osterioi' femora, l)ut tlie present species does not agree 

 with either of them. I will here jioint out the differences between 

 this and the allied species; the latter are ('. <iiabrala, Jac, C. 

 apicicornis, Jac, C. varians, Baly, C. laevicollis, Lef., ('. speciosa, 

 Lef. and ('. cili/i/ipes, Lefèv. of these, C. glahratu is a much 

 larger insect without raised elytral interstices, C. apicicornis has 

 geminate-punctate elytra, ('. varians is larger and has a closely 

 and distinctly punctured thorax, C. laevicollis has distinctly trans- 

 versely depressed elytra, but the author says nothing about tiie 

 interstices or the sex. C. sjtcciosu is descril^ed \\ ith fulvous an- 

 tennae and of 8 V'2 ^^^^^- length. C. venusta, Lefèv. has a sub- 

 Ijasal depression and sub-geminate punctate elytra, lastly ('. ci- 

 liatipes is 'i lines in length, has aciculate thoracic punctures and 

 long and dense til:)ial pubescence at the a])ex ; the structure of 

 the penis in the present species seems another mark of distinction 

 although nothing has ))een said al)0ut this organ in the allied forms. 



51. Colaspoides laevicollis, Jac. — Lefèvre's name having been 

 overlooked by me at the time of puldication (Genoa Annals, XXYII. 

 1889) 1 alter the name to ('. glabricollis. 



52. Aulacia flavifrons, n. sp. — Piceous or blackish, the head, 

 the basal joints of the antennae and the legs fulvous or llavous, 

 thorax rather closely punctured, elytra punctured in irregular 

 ro\\ s anteriorly, regularly posteriorly, the interstices at the sides 

 costate.

Head with a few extremely minute punctures, the vertex with 

 a central longitudinal groove and deej)er lateral grooves wiiich 

 unite in front . clypeus wedge-shaped , distinctly punctured . 

 labrum and ])alpi fulvous, antennae extending to the middle 

 of the elytra, ilavous, the terminal four joints black, the basal 

 two joints thickened, third and following jomts nearly e(piaL 

 slender, apical ones thickened, thorax more than twice as 

 broad as long, slightly widened at the middle, the sides rounded 

 and strontrlv narrowed in front, the siu'tace rather closelv ami
