Mr. E. E. Austen on Cutiterebra. L5i 
on the Oxford copy before me, Clark’s paper published in 
Trans. Linn. Soc. xix. pp. 81-94, and to “ iy ‘ Treatise’ on 
this genus, pl. 1. fige40” (ce. the “ Essay on the Bots of 
Horses and other Animals”), also occur. At the top of the 
page are five woodcuts, three of which refer to Pharyngomyia 
picta (here called by Clark Gstrus cervi), but which are not 
the same as the three figures with which the “ Note” as 
originally published in the ‘ Zoologist’ is headed, while the 
other two represent the types of Cutdterebra detrudator and 
C. atroz. "The latter figures are very bad, especially that of 
C. detrudator, which is not only valueless, but also mis- 
leading. The top right-hand corner of the Oxtord copy 
bears the following in Westwood’s handwriting :—“ (Zool. 
1847) and published separately by the Author for dis- 
tribut® with the addit™ of the 2 n. sp. from Mus. West- 
wood.” This statement of Westwood’s is supported by the 
fact that ‘‘ Addenda 1848” is not contained in any of the 
following libraries: British Museum (W.C.), British 
Museum (Natural History), Royal College of Surgeons, 
Linnean Society, Zoological Society, and Entomological So- 
ciety ; while Messrs. Dulau and Co. endeavoured in vain to 
procure a copy for me. Under these circumstances it certainly 
appears to be open to question whether the descriptions of 
the two species of Cutiterebra which will be found below were 
ever published at all, in the proper sense of the term. Since, 
however, the names were accepted by Prof. Brauer in his 
Monograph, while, as | have mentioned above, the paper is 
quoted by Hagen, I do not propose to interfere with them. 
The descriptions of C. detrudator and atrox occupy the rest 
of the page beneath the “ Note” C&c., referred to above, 
and run exactly as follows :— 
** Detrudator.—Cuterebra, nigra, holosericea, abdomine glabro 
cacrulescenti nigro, lateribus albo bicingulatis, posticéque rufo. 
**Habitat calidioribus Americes* (sic). Ex Museo Dom. West- 
wood. Vid. fig. 4. 
“ Descr. Caedit (sic) maximis hujus generis. Caput obtusum, 
vertice atro, inter oculos rufum, ore et inferne laté album hir- 
sutum. Thorax ater holosericeus, infra insertiones alarum et 
subtus, albus. Halteres concave concolores, erecte. Alae longi- 
ores aurulento-fuliginose. Abdomen laeté caeruleum ad latera 
cingulis duobus latis albis, apiceque hirsuto flavescenti rufo. 
Pedes omnino atri tarsis praelongis articulis sagittato-acutis. 
* In the Oxford copy Westwood has struck out the words “ calidio- 
ribus Americes,” written a ? above “ calidioribus,” and “(? J.O. W.]” in 
the margin,
