culis duobus juxtapositis conicis acutis et ulrinque ad latera spina 

 gracili, omnibus retrorsum nutantibus, armatum. Hemelytra api- 

 cem abdominis attingentia. Anguli apicales segmentorum abdo-

 This very distinct species belongs to StAl's groiip a and is some- 

 what allied to Ihe stili smaller A. Leontjevi Bergr., but is readily 

 distinguished from ail species of this group by the spined scutel- 

 lum and the markings of the membrane.

Forma brachyptera : corium apicem segmenti antepenultimi 

 abdominis vix attingens; membranaaugulum apicalem exteriorem 

 corii parum superans, margine apicali axi transverso corporis sub- 

 parallelo, dimidio exteriore hujus marginis levissime rotundato, 

 dimidio interiore levissime sinuato ; alas nulla:'. 



According to Distant (Proc. Zool. Soc. Lond. 1901, p. 332) the 

 type oi griseiventris Westw. belongs to the species later described 

 under the name S. Chevreuxi Noualh., and he says that the real 

 distinguishing character which séparâtes it from S. hœmatica 

 Germ. is the somewhat longer rostrum. The length of the rostrum 

 is, however, rather variable in the species of this genus and is not 

 a reliable character. Griseiventris as understood by Stâl is, as cor- 

 rectly pointed out by him, at once distinguished from hœmatica by 

 having the pronotum much more strongly punctured than the 

 corium and clavus. Should a re-examination of Westwood's type 

 prove that griseiventris Westw. is identical with hœmatica or 

 distinct from griseiventris Stâl, the latter must be renamed.

14. Odontopus sexpunctatus Lap. 



The spécimen belongs to the scarce typical form described by 

 Laporte, in which the anterior spot of the corium is divided 

 into two.
