Species donbtfiiUij placed in the Gams. 

 9. Baeturia ? sandaracata. (Tal). YII., figs. 1), a, h.) 



Batnria mntthtracata, Distant, Ann. Mus. Civ., Genoa, ser. 2a, vol. vi. p. 458, t. iv. f. 1, a, b (1888). 



(7 . Body above, sternum, ami legs pale testaceous ; abdomen beneath ochraceous. 



Tegmina and wings pale hyaline, the venation and the costal membrane of the first pale testaceous. 



The rostrum reaches the intermediate coxa;. 



Long. excl. tegm. <? , 30 millim. Exp. tegm. 72 millim. 



Hab. — Burma : Teinzo (Fea— Genoa Mus.). 



This species, which is the hirgest of the genus yet knowu to the writer, differs in some 

 siibgeneric respects from the other species. Thus the seventh apical area of the tegmina is 

 about equal in length to, and not longer than, tlie eighth area, and the oi^ercula are sufficiently 

 large to cover the sonorous cavities. 



B. sandaracata will probably form the type of a new genus, but at present I have left it 

 in Baiuria. I have only seen one specimen. 



Genus ACRILLA. 



Acrillii, Still, Trans. Ent. See. Lend. scr. iii. vol. i. p. 575 (1863). 



"Caput parvum, thoracis antico paullo augustius, vertice angusto ; fronte plus quam dimidium 

 latitudiuis faciei occupante, paullo prominente. Antennarum articulus primus brevis. Rostrum coxas 

 intermedias baud superans. Thorax lateribus baud dilatatis. Tegmina non nisi apice an^ustissime 

 marginata, abdominis apicem baud superantia, venis uluaribus basi distantibus, areolis apicalibus 

 undecim, areola discoidali venas longitudinales sex postice emittente. Alaj anguste marginativ, areolis 

 apicalibus septem. Abdomen maris valde inJ3atum, tympanis detectis, operculis miuutis brevissimis. 

 Pedes mediocres, femoribus anticis iucrassatis, trispinosis." 

 " Chloroci/stte * affine genus." 



1. Acrilla adipata. (Tab. XV., figs. 18, a, h.) 



Acrilht iiilijKiid, Sbil, Trans. Ent. Soc. Lond. ser. iii. vol. i. p. 575 (18IJ3). 



" Pallide sordide straminea ; tegminibus absque sordide hyalinis, stramineo-venosis. j ." 



" Long. 32, exp. tegm. GO mill." 



"Vertex oculo transverse vix duplo latior, ocellis posticis inter se et ab oculis seque longe remotis. 

 Thorax lateribus obtusissimis, medio et apice ;eque latus, ante medium utrimque Icvissime rotundatus, 

 postice subito ampliatus, impressionibus sat profundis, limbo postico angusto. Tegmina costa venaque 

 subcostal! contiguis, ilia baud dilatata ; areola basali interiore versus medium levissime ampliata ; areolis 

 apicalibus prima, sexta, septima, octava et uoua valde elongatis." 



Hab. — Malayan Akchipklago : Mysol (Wallace t — Brit. Mus.). 



* Chlorocysta is an Australian gemis. 



f The collections at Mysol were actually maile by Mr. W.iUacc's assistant, Charles .Mien, Mr. Wallace himself being 

 prevented by untoward circumstances from reaching that island.
