the insect above described in honour of this gentleman, who has 
exhibited such a remarkable zeal in favour of zoology. When his 
health declined in consequence of the bad climate, he yet made ar- 
rangements with his friends for enriching our collections at home. 
He returned to England, after resigning his laborious situation, 
broken in health but unsubdued in spirits, and hence we may hope 
that his health will shortly be re-established. The following cha- 
racters appear to me sufficient to form into a subgenus, allied to 
Oxynopterus, the above insect which I have denominated Lepto- 
phyllus, from the long leaflets which compose the antenne. 
Leptophyllus*, Hope. 
Caput feré quadratum, antic emarginatum. Antenne 11-articulate, 
1™° magno, 2° subtrigono, octo sequentibus feré aqualibus et la- 
mellatis, undecimo triplo majori. Thorax angulis anticis rotun- 
datis, posticis acutis, lateribus marginatis et carinatis. Elytra 
posticé acuminata, pedibus unguibus fere zqualibus. 
The anatomical sections of this genus are so fully figured by Mr. 
Westwood that there is no necessity for more ample details, as they 
may be detected on reference to the plate. 
Pectocerat, Hope. 
Caput fortiter emarginatum. Antenne valdé pectinate, novem ulti- 
mis articulis, dentibus gradatim increscentibus, ultimis longissimis,. 
Thorax antic rotundatus, angulis posticis acutis. Elytra acu- 
minata, pedibus simplicibus. 
The remaining characters may easily be seen in the accompanying 
plate. It appears to me that the above genus is mediate between 
Tetralobus and Ludius and Ctenicera. 
Pecrocera Cantort. Pect. fusco-castanea, antennis valde pecti- 
natis brunneis. Thorax niger tomentoque aureo aspersus. LElytra 
Susco-castanea, apicibus acuminatis. Corpus infra pilosum, cinereis 
flavisque capillis obsitum. Segmenta abdominis utrinque brunneo- 
maculata, maculis glabris. Long. corp. 10 lin. ; lat. 24 lin. 
Hab. in agro Assamensi. 
The above insect I received from Dr. Cantor before he quitted 
England, and I have since received it from the Khasyah Hills: it is 
named in honour of the above zealous naturalist. 
Pecrocera Metuu. Flavo-fusca griseoque variegata, antennis 
pectinatis. Thorax angulis posticis acutis, subtomentosus. Elytra 
postice valde acuminata, pedibusque fusco-flavis et pubescentibus. 
Long. corp. 12} lin. ; lat. 3 lin. 
Hab. circa Semlaa in agris Thibetianis. E Museo Dom. Melly 
descriptus.
