TarpMus abbreviatus, n. sp. 



T. breviusculus, rotundato-quadratus, granulis squamisque fus 

 densissime vestitus necnon setulis brevissimte cinereo-fuscis de- 

 missis parcc irroratus ; prothorace brevi, subsemicirculari, posticc 

 paulo angustato; elytris brevibus (postice truncate declivibus), 

 conspicue multinodosis (nodis concoloribus, rarius subrufescenti- 

 bus) ; antennis pedibusque brevibus, rufo-piceis. Long. corp. lin.

Habitat Gomeram, vulgaris ; in locis similibus ac praecedentes. 



The rather small size and rounded-quadrate outline of this Tar- 

 phius, combined with its rough, densely scaly but almost unsetose 

 surface, the numerous and somewhat largely developed nodes of its 

 shortened elytra, its sub -semicircular prothorax, and abbreviated 

 limbs, will readily separate it from the other species here described. 

 It appears to be very abundant in the laurel- districts of Gomera at a 

 high elevation, from whence I have just examined 71 specimens (all 

 exceedingly constant in their characters) which were captured by the 

 Messrs. Crotch. 



Tarphius monstrosus, n. sp. 



T. magnus, oblongo-quadratus, granulis squamisque fuscis dense 

 vestitus necnon setulis brevissimis minutis fulvis demissis praeser- 

 tim in nodis irroratus ; prothorace amplo, ad latera regulariter 

 rotundato sed ante medium latiore; elytris multinodosis (nodis 

 concoloribus, conspicuis, bene distinctis, altis sed vix inagnis); 

 antennis pedibusque rufo-piceis.' Long. corp. lin. 2-2|. 



Habitat in lauretis Gomerae, vulgaris. 



This is probably the largest of the Tarphii hitherto detected, 

 unless indeed the T. gigas from Teneriife (of which T have seen as 

 yet but two examples, one of which is scarcely smaller than the 

 larger ones of the monstrosus) be found to equal it in bulk. It is 

 remarkable., inter alia, for its numerous and well-defined elytral 

 nodules (which however, although greatly raised, are not particu- 

 larly large). It appears to be the Gomeran representative of the 

 Teneriffan T. gigas, though at the same time most abundantly dis- 

 tinct from that insect. It may be known from it by its differently 

 shaped prothorax (which is much larger and more developed, con- 

 siderably broader and more rounded in front, more recurved at the 

 edges, and with the anterior angles less acute), by its elytra being 

 very much more convex, with their nodules more numerous, con- 

 siderably more elevated, and better defined, by its sculpture being 

 less coarse, and its body less thickened and more clothed with a
