H, elongatus, Blackb. Since I described this species I have 
seem two more specimens (one of them a dwarf, long., 10 1.), 
and I find the tendency of the discal elytral punctures to run in 
strips between unpunctured intervals less marked than in the 
type. The species, however, is very easily recognised by the 
characters attributed to it above in the tabulation. 
HI, subseriatus, sp. nov. Ovatus; modice latus; nitidus; sat 
glaber ; testaceo-brunneus, in disco parum obscurior, pro- 
thoracis elytrorumque marginibus omnibus anguste nigri- 
cantibus ; antennis sat elongatis; prothorace in disco postice 
tuberculo conico et ante tuberculum carina brevi longi- 
tudinali armato, subtilissime (puncturis nonnullis paullo 
majoribus intermixtis) punctulatis, parte laterali modice 
reflexo confertim subtiliter granulosa, basi sinuata, angulis 
posticis minus acutis, margine haud ad_ perpendiculum 
directo ; elytris in disco sparsim subtiliter confuse punc- 
tulatis et 7-seriatim granulis distinctis instructis (granulis 
in disci margine externo quam cetera sat majoribus), 
seriel subsuturalis parte antica circiter tertia vel quarta 
leviter carinata, parte laterali ut prothoracis granulata et 
discum versus granulis nonnullis majoribus instructa, 
sutura sat fortiter carinata, disco fortiter convexo. Long., 
15—1984 1.; lat., 92—92 1. 
The characters of this species that appear to me to be of 
specific value are,—the comparatively light colouring with all 
the margins of prothorax and elytra narrowly blackish (this is 
certainly not the result of immaturity); the sculpture of the 
expanded lateral portions of the prothorax and elytra (not punc- 
tulate, though apparently so to a casual glance, but under a 
strong lens) consisting of fine and close granulation ; the disc of 
the prothorax with a well defined short longitudinal carina in 
front of the basal tubercle or horn; the absence of carinz 
(except the sutural one, and a short subsutural one forming the 
anterior part of the first row of granules) on the dise of the 
elytra; the presence of seven fairly regular rows of granules on 
the disc of the elytra, the interstices being finely, sparsely, and 
confusedly punctulate, and the absence of an erect edging on the 
lateral margins of the prothorax. H. princeps, Hope, is not 
intelligibly described and might be anything; the dise of its 
elytra is said to bear ‘sex punctate line elevate” and to be 
sparsely impressed with ‘puncta atra elevata,” whatever that 
may mean ; moreover the description of its colouring does not at 
all agree with the present species,—which, however, is as likely 
as any other known to me to be H. princeps. If “ puncta 
elevata” are granules the present species may be definitely 
asserted to be distinct from princeps as the disc of the elytra
