maiulibiila is I'oiisidoi'ably expiiiided, laiiiellai' at its distal cud; 

 the pi'oxiinal end is lused with tlie basal riiififof tlie luaiidibula. 



Tlie g-uath(H-hilai-iiiiii, compai-ed with that of >S'y///(/'/■Ny/rl•/^^• as 

 I'epreseiited bv voni Rath, is shorter; the proximal part 

 (laniellooardiiies) is bi'oader as the outer inar^iiis are almost 

 parallel and do not converj^e backwards. Tlie mentum is 

 distiiu'tly divided into two sclerites. 



The above mentioned features are not all of equal value, 

 but some of them, such as, namely, the structure of tlie liead, 

 are undeniably of first rate impoitance and are well suited to 

 cliaracterize a distinct family. 



Tlie limits ot this new grouj) cannot at present be better 

 delineated, as very little is known of these interesting forms. 

 However, it could be ascertained that Sphn'nifliL'ri iim I iJn' ill mix inn 

 Sauss. and Zehnt., from Madagascar^ the type of wliicii is 

 preserved at tlie Paris Museum, participate of the structure of 

 I'ljlloifoiini as far as the liead, the gnathochilarium and the 

 traclieal stalk of the niandibula are concerned. Therefore, it is 

 likelv that the Australian and the South Afi'ican (including 

 Madagascar) species will liave to stand togetlier in one family — 

 Spha?rotheriid{e — equivalent to the ohl (Brandt's) genus 

 Sji/iii'i-nflifri inn, wliile the Indian forms of iSp/niTdjiiriis, and 

 probablv of Arfln-nsjilnrrd and of Zepliroiiiit, will have to be set 

 apart in another family, equivalent to the old (Bi-andt's) genus 

 SjiJitrrnjiii'iis^ for wliicli the name Sphseropceidfe is proposed. 



Turningto the genus L'iili(is(iiin(, the following details observed 

 on both species hereafter described are well wortli nientioning- 

 and may be characteristic foi- that genus. 



Antennae veiy short, not much longer than the first tergite ; 

 tlie sixth joint is neai-Iy cylindrical, similar in both sexes ; the 

 last joint is tipjied with four strong sensory cones. In S. 

 lihidiuosuiii, the antennas are elongate, nearly twice as long as 

 the first tergite ; the sixth joint is slightly swollen distally ; 

 the last joint shows many chitinized, contiguous cells closed with 

 a membrane, in the middle of wliich stand a tiny comb. 



3 Whether S. Ubidinosmn, S. and Z., is a good representative of 



the j<enus SpliccrotJieriuiih is not known.
