OF THE COLEOPTEROUS GENUS BOLBOCERAS. 13 
the Athyrei, must be regarded as very aberrant species in the family of which our Geo- 
trupes is the well-known type. 
It has been thought advisable that a continuation of this paper, containing descriptions 
of many additional new species of Bolboceras from India and other foreign regions, should 
be published as a distinct memoir, which accordingly appears as the following article. 
1. BoLBocERAS (ELEPHASTOMUS) PROBOSCIDEUS, MacLeay, ut supr. citat.

Obs. Caput et pronotum delineavi in Tas. TI. fig. 1. ex individuo typico in Musæo Societatis Entomo- 
logicæ Londinensis. 
Obs. 2. Figura maris in opere Griffith’s Animal Kingdom, Ins. pl. 40. fig. 4, 4 a, 4 b. 
Obs.3. Varietatem maris (cum fœminâ Bolb. Australasie omnino congruenti copula captam) Societati 
Entomologicæ Londinensi communicavit D. F. Cox. Caput maris cornu perpendiculari infero caret, 
angulo parvo prominente locum ejus occupante. 
2. BOLBOCERAS (ELEPHASTOMUS) KIRBIT; castaneo-fulvus, capitis cornu antico porrecto 
brevi truncato plano subtüs in spinam bifidam haud producto, vertice carináà brevi 
transversä, prothoracis lateribus valdè punctatis utrinque fossulatis ; disco postice 
canali abbreviato longitudinali instructo.—Long. corp. lin. 9. (Tas. III. fig. 2.) 
Bolb. (Elephastomus) Kirbii, Hope MS. 
. Hab. in Terra Van Diemen. In Mus. Hope. 
El. proboscideo minor, corpus castaneo-fulvum. Caput elongatum; vertice carina transversá, quasi e 
tuberculis conjunctis formatä, in medio instructo; parte ante carinam porrectá subquadratä gra- 
nulosá anticé parum latiori apice utrinque recté truncato, cornu antico abbreviato plano, antic? por- 
recto, apice truncato arcuato. Caput subtüs parte anticä tumidá; clypeo deflexo, labro ad apicem 
ejus affixo. Mandibulæ angustæ, fere similes, apice acuto denteque parvo subapicali armate. Pro- 
thorax anticé lzevis, nitidus ; lateribus punctatis et utrinque fossulä rotundatä instructus; disco ante 
medium cariná tenui transversá (in medio interruptá) canalique tenui punctato longitudinali pone 
medium ante marginem posticum obliterato. Elytra striato-punctata; striis 14 in singulo elytro ad 
apicem elytrorum extensis. Tibiæ anticae dentibus 6 nigris extüs armatæ.

This appears to be the insect given by Mr. MacLeay as the female of Elephastomus pro- 
boscideus. It is however a male, and is given by Dr. Klug as a variety of the male of 
that species. The insect above described appears, however, to me to be sufficiently distinet 
as a species from the former t. 
3. BorsocERas REICHIT; castaneus nitidus, capite cornu valdè elongato erecto, prothorace 
antic’ valdè deflexo et subeoncavo cornubus duobus crassis longitudine capitis por- 
rectis lateralibus anticd armato: singulo versus basin dente obtuso erecto instructo;

* The upper division of the inner lobe is multispinose ; Dr. Klug has represented it as distinctly bifid in both sexes 
of B. Australasie. 
T The variety of the preceding species, wanting the PUR 
sheet has been in type, seems to confirm Dr. Klug’s opinion.
