Spectres 2 (88)—CREMASTOCHEILUS CASTANEZ. 
Puate XIV, Fic. 4. 
Precedenti (Cr. canaliculato) minor, niger subopacus ; elytris vitta tenui transversa lutea; capite et pro- 
thorace sparsim et rude punctatis; prothoracis parte latiori pone medium sita, lateribus antice sensim angus- 
tatis ; disco canali medio vix conspicuo, angulis anticis nodiformibus ; menti margine postico profunde inciso.

Syn: Cremastocheilus castanee. Knoch, Neue Beytr. p. 115, pl. III, fig. 1, with details, (nee Schaum in Germar 
Zeitschr. iii. p. 255.) 
The head is small, convex, thickly covered with minute punctures, with the fore margin strongly reflexed 
and sharp; rounded as seen from above, but arched upwards (or emarginate) as seen from the front. The 
mentum is very deeply notched in the middle behind. The prothorax is transverse, opaque, less thickly covered 
with setose punctures than the head, with a very slight longitudinal impression down the centre. The anterior 
angles are porrected, glossy, black, curved inwards towards the eyes; the sides of the prothorax are emarginate 
behind the angles, and are thence curved gradually outwards, the widest part being slightly beyond the middle ; 
the posterior lateral angles are acute, conical, glossy, black, rather elevated and directed outwards towards the 
shoulders of the elytra; the sides of the pronotum within the lateral posterior angles are rather deeply impressed. 
The elytra are wider than the prothorax, opaque, rather thickly covered with oval cicatricose punctures, emitting 
slender luteous sete ; each elytron with a small transverse not very distinct luteous mark near the lateral margin, 
beyond the middle ; the dise of each is depressed. The pygidium is covered with minute luteous sete. 
‘This species (undescribed by anybody else than Knoch) is of the size of C. variolosus ; the white spot on 
the elytra is scarcely visible (and therefore not described by Knoch) ; the head and thorax sparsely and grossly 
punctured ; the thorax broadest immediately before the hind angles, and gradually narrowed towards the apex. 
This is the true Castanee of Knoch, D. Melsheimer having a specimen in his collection which was transmitted 
by Knoch to his father. Both species have the canalicula of the thorax, but they are sufficiently distinct. 
Knoch’s figure of the thorax of Cr. castanee is pretty correct. Iwas led into the belief that Cr. canaliculatus 
was the true Cr. castanee by the Berlin Museum, where Cr. canaliculatus was considered as synonymous with 
Knoch’s insect ; and, moreover, by the occurrence of the two principal characters of Cr. canaliculatus, viz. the 
white spot and the canaliculation of the thorax. The doctrine to be derived is, that we have to learn every 
day.’ (Schaum, in letter of January 9, 1848.) 
Srecres 3 (89)—CREMASTOCHEILUS HARRISIT. 
Niger, nitidus; vel piceo-niger, subtus albido-pilosus: capite postice punctato, thorace leviori subquad- 
rato, angulis prominentibus tuberculiformibus, postice punctato antice levigato, utrinque foveis tribus (pl. XIV, 
fig. 10); primo nempe baseos magno punctato, seeundo intermedio profundo, tertio anguli antici minori, his 
ultimis levigatis; postice fasciculo pilorum albidorum notato; elytrorum basi humeris apiceque gibbis, punctis 
magnitudine et forma variis confluentibus, setulis albidis decumbentibus inspersis ; menti margine postico pro- 
funde emarginato.

Cremastocheilus castanee. Kirby, olim Zool. Journ. ii. p. 517 ; Harris, Journ. Acad, Phil. vol. v. p. 384. 
Mr. Kirby’s type of this species is now preserved in the Hopeian Collection at Oxford. 
There is a specimen in the Royal Museum of Berlin’, from the Collection of Dr. Schaum, now numbered 
1 Tn addition to Cr. canaliculatus, Kirby, from New York, Cr. castanee, Knoch, from Pennslyvania, and the insect 
above mentioned, No. 41,585, all having the mentum deeply notched, the Berlin Museum possesses two other insects from 
the Schaum Collection without any specific names attached to them, and which also belong to the same group. 
No. 41,579, from Illinois (Coll. Schaum), 42 lines long, with the prothorax setose and vyariolosely punctured,
