now in the Berlin Museum, No. 41,582. As Dr. Schaum also possessed the present species, it is not to be 
supposed that he would not have perceived the identity of the two insects, if such had been the case. 
Species 18 (104)—CREMASTOCHEILUS MEXICANUS. 
Niger, opacus, elongatus, rude punctatus, setis brevibus luteis parce obsitus; thorace postice utrinque 
impresso, lateribus rotundato, angulis anticis porrectis, acutis, posticis tuberculiformibus ; disco linea abbreviata 
media parum impressa ; mento transverse-rotundato, concavo, margine postico integro rotundato.

vol. ii. pl. X, fig. 8; Burmeister, Handb. iii. p. 682. 
The front of the clypeus is widened, reflexed, and smooth. The prothorax is proportionably broader than in 
Cr. variolosus, more rounded at the sides, the emargination preceding the posterior angles much less distinct, 
the anterior lateral angles more porrected, pointed, scarcely raised, and not deeply impressed or grooved within, 
and the hinder angles not so much exserted, with their outer extremity raised. The disc is more sparingly 
marked with shallow punctures, occasionally with a slight central longitudinal furrow. The elytra are much 
longer and proportionably narrower than in Cr. canaliculatus, the length exceeding the width by more than half 
the latter, more sparingly marked with very shallow oval punctures emitting fine yellow sete, the punctures near 
the lateral margins being rounder and deeper. The scutellum at the base is very finely and rather closely 
punctured, the punctures very shallow, towards the apex they become larger and wider apart, but still very 
shallow. The abdominal segments are constricted at the apex, the ventral surface is glossy, punctured, and 
luteo-setose. The tarsi are broad.

(Ante, p. 26.) 
Since the preceding Monograph of the Cremastocheilides was prepared for the press, a memoir of the Ceto- 
niide of the Moluccas and the Sunda Islands has been published by Herr Mohnike, in the Archiv. fir 
Naturgeschichte, 37 Jahrg. i. 225, in which is given a description and wretched figure of an insect from Java 
closely resembling Callynomes Vollenhovii, with the name of— 
Sprcres 1 (105)—CHOLERASTOMA SPONDYLIDEA. 
‘Supra plumbagineo-nigrescens parum nitens, elytris postice juxta marginem litura parvula albida signatis, 
subtus nitidior, atra.’

The tarsi are described as 4-jointed in both sexes, and the basal joint of the antennz as ‘sehr gross.’ 
T am therefore led to suppose that the insect which Mohnike has described is another species of Callynomes 
which name must in strict justice be replaced by that of Cholerastoma, although the author has not described 
the more important structures of the maxilla, mentum, prosternum, tibial spurs, and abdominal depression in 
the males. 
A specimen of the male of this species in the Collection of Mr. Higgins measures 84 lines in length; it is 
entirely black (except a small oblong spot near the outer margin of each elytron beyond the middle), only 
slightly shining, and is destitute of sete. The head and pronotum are very thickly punctured ; the latter has 
its widest part before the middle, and there are only very slight traces of two small impressions on each side. 
The elytra are coarsely punctured, very slightly costated, and with the dise rugose.
