ineluded by Sig Thor, 1985 (loc, cit.) and also by Womersley, 1937, in this 
subfamily were Caluthrombium Berl, 1918, aud Neotrombicdium Leonurdai, 190). 
The first of these, however, has a very different type of erista, which conforms with 
that figured bry Berlese (1912) for the genuy J'ananpodus Taller, 1882, and tala. 
thrombium (type CO. puoli Berl.) must therefore be assigned to Sig Thot’s lanan- 
podinae. 
he genus Neotrombrdawm also differs widely from the Microtrombidtinae m 
thal the erista is enlarged anteriorly into a more ov less triangular area or magus, 
in this respect showing hamelogy with that whieh | have found recently in the 
nywiphs of the genus Leeuwanhoekia (Acomatucarus). Neotrambidrum must theve- 
fore. be removed from the Mierotrombidiinae, 
The gennos Munriquae with M. bequoert? B.& K. as type has recently been 
erected (1942. Rey, Acad. Columbiana cd. Oi, Mxact, Bogota, 17, 110-127) by J. 
Boshell and J. A, Kerr for six species of Mierotrombidiinae from Columbia, Sonth 
America, To the generie description tbe features stressed are (1) eristi auleri- 
orly rod-like with a subposterior sensillary area, (2) palpal tibia with strong 
claw, smaller accessory claw, iwo peebines, and an external spine. and (8) the 
dorsal setae of varied forms, Now (hese characters are those found in Mieralrom- 
bidhum. (Haller, 1882, sste.), with pusilla Hermann, 1804, as type, except that! 
while venerally present, the external spine of thy palpal tibia is absent in pusillnm 
and one or two other species; this, however, hardly justifies a generic separation. 
Tn the same paper Boshell aod Kerr also deseribe a number of species of 
Uterwtrombidmn s.l., whieh in the varied and different forms of dorsal setae, (it 
into several of the genera into which Mieratrembidiwemn sl. in the present paper is 
divided. Even the species included in Momriquia by the authors, belong ta several 
ul these genera, neluding Mieratranhidiawm s.str, 
in Micretrombidiwm s.ste. should be placed Manriquia rocar B.& K,, sanperl 
B.& K., and 2% bolivarensis B. & K., and also Microlrambidium wilson’ G. & K. and 
howe BO & BK. In the genus Lehinolhrombium should be included Meanriquiv 
bequaertii BO& K., Mierotrombidiwm duarte B. & BK. anid bugher: By & KR. 
Micratrombidium urborealis B, & Ko and acumen B.& K. wonld seem to belong 
to Camerotrombidium while Microtrambidium sopert B. & I, would be a Foltotram- 
hidiywm, and carmrensis possibly a Hiotrombuliam. Manriquia restrepot B. & K. 
and manriquia B. & K. may be placed in Moleotrombidium. 
Boshell and Kerr in their paper also describe Ute larvae veared from eggs tail 
by a captured adult Manriynia bequoert, From the description and figure given 
the larva comes close to those described by Oudemans (1912) as belonging to the 
genus Parathrombium Bruyant, 1910. Tt is also somewhat similar, except that. 
the chelicerae are free and not enclosed in a chitimous dentate ring and that the 
claws of the third leg are normal, not deformed, to the larvae of Camerotrombidiwm 
etmale (Hirst) described in the present paper, 
The present paper is the first of a series in which it is intended to eritically 
review the adult specics of Trombidiidae of Australia and New Guinea, The 
latter area is nchided, as amongst new material available there are a wamber of 
apecies, collected in that area by Maj. G. M. Kohls of the American Serub-yphus 
Covamission, which ean be referred to some of those described, very inadequately, 
ly Canestrini m 1889. 
In the Microtrombidiinae as cestricted herein, it is shown that, followme the 
work of Berlese and Sig Thor, good generit characters are (o be found in the 
types of dorsal setae; the form of the evista aud of the palpal tibia being of eub- 
family value. Specific characters are to be found ie the dimensions of the front 
tarsi and metatarsi and iu the lengths and slegrees of ciliation of the vlorsal selas,
