ME. P. P. PASCOE ON THE LONGICOENIA OF AUSTRALIA. 99 



3^°-6 vel 7™""* apice spinosis. Prothorax elongatus, lateribus tubercu- 

 latus (ex. aberrans etpolita). Elytra modice elongata, apicibus uni- 

 vel bispinosis (ex.pubescens). Femora valde clavata, basi elongata. 

 Corpus angustatum. 

 The type is Callirhoe liguttata, Don. {Stenochorus) . The long, 

 strongly clavate femora, and narrow body, will in general at once 

 distinguish this genus. These characters hold good for all the spe- 

 cies except G. aherrans, which has only moderately clavate femora. 



Atesta. 

 Frons brevis, apice angustata. Labrum minutum. Antennas medioeres, 

 articulo tertio apice valde spiuoso, quarto obsolete spinoso, cseteris 

 inermibus. Prothorax elongatus, lateribus tuberculatus. Elytra 

 parallela, apice rotundata. Femora in medio incrassata. Corpus mo- 

 dice elongatum. 

 The type is Atesta halteata, Pasc. (^Phoracanthd) . The only 

 genus with the apex of the combined elytra rounded ; A. Angasii, 

 is so far exceptional that a very short mucro may be seen with 

 the aid of a lens at the sutural angle. 



Allotisis. 

 Frons brevis, apice lata. Labrum breve, transversum. Antennce setacese, 

 articulis tertio et quarto apice subspinosis. Prothorax elongatus, la- 

 teribus tuberculatus. Elytra parallela, apicibus truncatis, baud spi- 

 nosis. Femora clavata, basi elongata. Corpus gracile. 

 The type is Allotisis scitula, Pasc. (Phoracantha). The spines 

 on the antennae are reduced to a minimum in this genus, while 

 the truncated apices of the elytra mark the first approach to spines, 

 which we find throughout the remainder, 



BlOSPIDES. 

 Frons subbreve apice subangustata. Labrum transversum. Antennee 

 articulis depressis, 3^°-8™™ apice valde spinosis. Prothorax longitudine 

 baud latior, lateraliter spinosus. Elytra oblonga, apicibus bispinosis. 

 Femora sublinearia, tibm et tarsi graciles. Corpus robustum. 

 The only species is Diospides ohscurus, Don. (Stenochorus) . It 

 is principally distinguished from PhoracantTia by its linear or 

 nearly linear femora. 



Trtphocharta. 



Frons paulo producta, apice angustata. Labrum transversum. An- 



tennce corpore vix longipres (in foem. breviores), articulis S'^-S™" apice 



bispinosis. Prothorax parvus, lateraliter spinosus. Elytra ampliata, 



apicibus bispinosis (ex. Odewahnii). Femora linearia. Corpus per- 



•^ amplum. 



The type is Phoracantha hamata, Newm. The genus is remark- 

 able for its small prothorax and its large elytra.
