REPORT ON ZOOLOGY, MDCCCXLII : 
five-jointed tarsi ; E. contumacc, taken from under the bark of the 
Eucalyptus. Deretaphrus, vid. under Colydii. 
Xyletinus ornatus, Germar (Faun. Ins. Eur. 22, 2), black with a grey 
hairy coat, and the tip of the striped and pointed elytra red, is a new 
species from Hungary. 
Ptinus exulans of the reporter, is from Van Diemen’s Land (Arch. 
18L2, i. p. 147). 
Imhof has enriched Apate with three new species from Guinea (Ver- 
handl. d. Naturf. Ges. zu Basel, v. p. 176): A. producta, tonsa, and 
crinitarsis. The reporter has added one from Van Diemen’s Land, 
A. collaris (Arch. 1842, i. p. 148). 
Harris (Ins. of Massachus. p. 52), has described two new North 
American species, Lymexylon sericeum, and Hylecoetus americanus. 
He is in doubt if the former actually belongs to Lymexylon. In this I 
do not agree with him. A female, however, is alone known to me. On 
the other hand, in the HyleccBttis americanus, the presence of a single 
red ocellus in the middle of the forehead, as in Attagenus, &c., is very 
striking, and appears to indicate that this beetle, which is not known 
to me from personal inspection, is incorrectly placed under Hylecoetus. 
The reporter has also added a new species to this small group, Lymexy- 
lon australe, from Van Diemen’s Land (Arch. 1842, i. p. 147). 
SiLPHALEs.— In D’Orbigny’s Voy. d. I’Amer., Blanchard has described 
the following new species of this family : — Necrophorus didymus, Brull., 
and N. scrutator, BL, both from Bolivia ; Silplia apicalis, Brull., from 
Potosi (Bolivia) ; >8. erythrura, Blanch., from Monte Video ; 8. disci- 
collis, BruU., from Bolivia ; the last agrees with the 8. cayennensis, 
Sturm. Cat. 1826, t. 2, f. 10, whilst the one preceding is identical with 
8. hoemorrhoidalis, St. 
Agyrtes glaber {Tritom. glabr. Payk., Gy 11., Zett.), from the north of 
Sweden, has been figured by Germar (Faun. Ins. Europ. 22, 1). 
Catops australis of the reporter, is from Van Diemen’s Land (Arch. 
1842, i. p. 243). 
Schiodte (Kroyer’s Naturhist. Tidsskr. iv. p. 107) has corrected an 
error of Leon Dufour, who had represented 8ilpha as having an azygos 
secreting organ of the urinary bladder, consisting of a vessel, and a 
bladder voiding into the rectum. That bladder is the caecum, and the 
vessel a vessel-like appendage to it, similar to the corresponding parts of 
Dytiscus. 
Palpatores. — Aube (Ann. Soc. Ent. de Fr. xi. p. 233) has enriched 
the group of the 8cydmoenus thoracicus with two new species : 8c. la- 
ticollis, from the Jura, is double the size ; 8c. minutissimus, from the 
island of Louvier, is only half the size of 8c. thoracicus. 
8cydmcenus anfidotus, Helf , has been figured by Germar (Faun. Ins. 
Eur. 22, 3).
