344 REPORT ON ZOOLOGY, MDCCCXL1V. 



variety of the preceding, the only difference being a couple of deep irregular 

 impressions at the base of the corslet. 8. barlurum (Dup. ib. 235) it is 

 likely should be united with No. 6 as the other sex, being distinguished 

 merely by the after-trunk (hinter-korper) being triangular rather than 

 parallel-sided. /3. Intermediate ridge of the corslet without the groove. 

 9. servillei (ibid. 236), new species, resembles S. genei, only the lateral tooth 

 of the corslet is more deeply notched; and the tubercles of the marginal 

 ridge of the shards are somewhat stronger. It seems not improbable they 

 may both be varieties of S. siculum, in which the groove in the intermediate 

 ridge of the shards is often very slight and faint, and may be liable to 

 vanish yet more completely. 10. bartlielemeyi (ibid. 236), new species, from 

 Upper Egypt, \\.jlexuosmn (ib. 237), new species, and 12. tricuspidatum, 

 P., both from Egypt. 13. maillei, Sol. (ib. 239), from Tunis, is S. wagneri, 

 Er. (Wagner's Algiers, iii, 179, 22.) 14. serratum (ib. 240), new species. 

 15. reqnieni (ib. 241), new species, from Tunis. 16. multispinosum, Sol. 

 (ibid. 241), from Barbary (= S. tomentosum, Er., ibid. 178, 21.) 



4. Genus Echinotus, Dej. Corslet without a lateral tooth, but with a 

 slender process in front ; third joint of the feelers very long ; the posterior 

 thighs thin, suddenly forming a little club at the tip ; corslet and shards 

 with prickly tubercles on the back. One species, E. spinicollis (Klug, ib. 

 243), from the Cape. 



5. Genus Oyrtoderes, Dej. Corslet expanded into a sort of hood over the 

 bowed head; mouth free. The author gives three species: 1. sinttosus 

 (ib. 246), which has the turned-up margin of the shards bellying, with an 

 elevated longitudinal line. 2. my r it us (ib. 247), with the same margin 

 descending perpendicularly ; the insect entirely covered with a black earthy 

 coat. 3. curculioides (ib. 248) resembling the last, but the coat clay-colour, 

 as in the first. But all these are, doubtless, mere varieties of one species, 

 the Braclii/ccrus cristatus, P., from the Cape. 



6. Genus Cryptogenius, Sol. Distinguished from the preceding by the fore 

 breastplate (prosteruum) covering the mouth like a cape. Species 1. Cr. 

 dentaltts (ib. 250, Cyrtoderes id., Dej. Cat.) 2. Cr. spinolcc (ib. 251), new 

 species, with the last joint of the feelers shorter than the foregoing, while 

 these are equal in the first species, in which also the first rib of the shards 

 forms a sharper projection behind. But as the two agree otherwise in all 

 material points, the difference seems to be rather sexual than specific. 



The section of Moluris proper is thus subdivided. 



Subdivision 1. Last joint of the jaw- palps small, oval, or slender, and 

 slightly truncated. 



7. Genus Physogaster, Latr., Lac., Guer. A single species, Ph. mendo- 

 citius, Lac. 



8. G&av&Thylacoderes, Sol. Distinguished from the preceding by the pro-
