Mr. J. Micrs on a new species of Lardizabala. 431 



my long experience in it has not furnished me with any instances 

 of any of them living upon trees, with the exception of the Tricon- 

 dyla, Collyrides, and certain Cicindelce. The Casnonia and Ophio- 

 nece are in the habit of ascending grasses and low herbs, and certain 

 Lebiidm and the genus Catascopus live under the bark of trees : 

 this is all. As to the insect described above, although it appears 

 to adapt itself with facility to a variety of physical circumstances, 

 and although it takes occasionally to its wings and flies into 

 houses in the evening, I have never found it upon trees. 



XLV. — On another new species of Lardizabala. 



By John Miers, F.R.S., F.L.S. &c. 



[Continued from p. 192.] 



I have lately observed, in the herbarium of the Paris Museum, 



another undescribed species of this genus, the description of 



which I here append to the former : — 



3. Lardizabala infuscata, n. sp.; — volubilis, foliis biternatis, 

 foliolis ellipticis apice vix acutis vel obtusiusculis, puncto cal- 

 loso onustis, terminalibus in petiolulum longiusculum cuneatis, 

 lateralibus sessilibus basi insequalibus et obtusioribus, glaber- 

 rimis, crasso-coriaceis, supra intense fusco-viridibus, nitenti- 

 bus, simpliciter nervosis, nervis patentibus immersis, subtus 

 pallidioribus brunneis, lucidis, costa nervis venisque promi- 

 nentibus, marginibus revolutis integris vel obsolete crenulatis ; 

 stipulis orbicularibus majusculis, fuscis; racemis <S axillaribus 

 folio sub-brevioribus. — Chile Australis : v. s. in herb. Mus. 

 Paris (Hombron, Voyage de PAstrolabe et Zelee). 



This species is at once recognized from L. biternata by the 

 extremely dark colour of its leaves and by their much greater 

 thickness and opacity, thus offering a strong contrast to the 

 light green colour of the typical species. In the latter the leaf- 

 lets are 3-nerved from near the base, but in this plant no such 

 lateral nerves are present ; in the typical species a portion of the 

 early pubescence is always found remaining upon the nervures 

 and petioles, but here they are quite free from hairs; the petioles 

 of the intermediate leaves are also much longer in this species. 

 The internodes between the axils are 2^ in. long; the leaves 

 altogether are 3^ in. long ; the main petiole is 5 lines long ; 

 the two lateral secondary petioles are 5 lines, the intermediate 

 one 12 lines long; the lateral leaflets are 17-21 lines long, 

 9-11 lines broad; the intermediate leaflets are 2^ in. long, in- 

 cluding their petiole of 3 lines, and 10-14 lines broad ; the orbi- 

 cular stipules are 6-8 lines in diameter ; the raceme is 2^ inches 

 long, with about fifteen alternate male flowers.
