The rla.H.sitit-ati«in of the lii'io-Au>trulian I'a.s.s4didae wa.s recently revise<l ((Jnively, 

 19140, pp. 191-304, 316-318 and 338-330). They fidl int«i two di.stinct McctionH, of which 

 orie forms the sub-family AulaciK-yclinae. The residtM of my previ<ius work on the 

 cla.s^itication of the other .se«"tion have been .suminari/.e<| as follows (191 4r, pp. 336-337): — 

 " The siH-ond sort ion has been sub-«li\ ulrd into the I'h-iirnrimi, Anrntufi, ifarnJitms, 

 Kaiiftiofoidfn, I'rutomoctxlua, IlijiHTpUsthi-nna, linaphalornrmta, I'leslJwuus, (iuiuitai, 

 Taniuiinua and hiitaiilax grotjps. Of the.se group.H the first three and the la«t two 

 apjM'ar to be of nxwt im|M)rtaiu'e, and have been provisionally ranked as .subfamilien, 

 the remainder being put together into a single subfamily whi< h takes its name from the 

 genus (iiuipfialocnemis. Their rank cannot \)c finally settled without reference to .\merican 

 and African ■-iiecies." 



Thi' number of subfamilies thus recogni7,e<l is undoubtedly t<M» great in comparison with 

 the classification of .Vmeiican and African forms outlined almve, and may atlvantageously 

 be roiluce<l to two. One of these, the I.^'ptaulncinae, remains as defined in my previous 

 l)aiK«r. The .sec«»nil. which may be called the Macrolininae. includes all the rest.

The di.strti end.s of the anterior roxae alxnit on a level with the 

 Kcnernl surface of the int«*rroxal |M)rtion of the j»rontenuini, 

 which ia \-i»ible between theni ; at least one pair of the usual 

 (Miired cephalic tul)ercles pn'-irnt in most species ; the middle

 ' The anterior lower tooth nion* or less columnar, at least on the 

 riaht side, bcinf; compres.<ied U'lore and behind or even 

 concave behind ; or all three terminal t^'th <lireet<sl forwards, 

 and armnged in a line one above another; or the dentitio:i 

 incomplete ; the head always symmetrical (American and 

 Afnran forms) 

 The :nit'Tior lower tooth conical, compressed above and l>elow ; 

 t!' liwest tenninal tooth «lirecte«l inwards and set n little 

 1m lui.d the other two ; the head often asymmetrical -always 

 so io forms with reduced dentition (Indo-Au<(tralian forms ) . .
