The above insects, male and female, were brought to this country 

 by Dr. Horsfield from the island of Java ; at first I was inclined to 

 consider the species as the mucronatus of Olivier, but the figure in 

 Voet is quite different. I have no hesitation in recording it as another 

 species, and it may be remarked here that the above insects are in a 

 good state of preservation, and that all the species of flabellate Elaters 

 with pubescence should be described immediately they are captured, 

 as when dead they change considerably in colouring, often turning 

 black and greasy, so that it is impossible accurately to describe them 

 as in their original state. 



Leptophyllus Strachani. Lept. (Mas) piceus, capite antice ex- 

 cavato antennis, capite cum thorace fere duplo longioribus , ely- 

 trisque acuminatis. Caput fere quadratum, antice excavatum ru- 

 gosum, antenna thorace duplo longiores, lamellis elongatis et ferru- 

 gineis. Thorax undique marginibus elevatis conspicuis, angulis an- 

 ticis parum productis , obtusis, posticis acutis et extiis divergentibus. 

 Elytra valde acuminata marginata picea et aurato-tomentosa. 

 Corpus infra concolor,femoribus tibiisque compressis. Fcemina ad- 

 huc latet. Long. corp. 26 lin. ; lat. 7 lin. 

 The above species was brought to this country by Mr. Strachan, 

 long time a resident at Sierra Leone. His zeal in urging his friends 

 to collect insects in that climate has been the means of considerably 

 enriching our metropolitan collections, and to him chiefly we are 

 indebted for our acquaintance with the Goliath beetles. I have named 

 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 antennae. 



Leptophyllus*, Hope. 



Caput fere quadratum, antice emarginatum. Antenna 11-articulatse, 

 l mo magno, 2 d0 subtrigono, octo sequentibus fere sequalibus et la- 

 mellatis, undecimo triplo majori. Thorax angulis anticis rotun- 

 datis, posticis acutis, lateribus marginatis et carinatis. Elytra 

 postice acuminata, pedibus unguibus fere sequalibus. 

 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. 



Pectoceraf, Hope. 

 Caput fortiter emarginatum. Antenna valde pectinatse, novem ulti-
