16. ACANTIIOSOMA BINOTATA. 



Tcsiacea, longi.ovala, fusco punctata ; caput elongatum, ant'ice glahrum ; 

 antcnncc (jracika, corporis dimidio brev'iorcs ; thorax fascia glabra 

 antice testaceo pallido marginata, vitta lateribusijuc paliide testaceis, 

 spinis longis subrecurvis ; scutel/um testaceo paliido utiivitlatiim, 

 plagis duabus lateralibus apiceqite fuscis ; venter fusco inaculariler 

 bivittalu/i, xpina coxas medias altingente ; alee anticw macula paliide 

 teslacea fusco marjinala. 



Testaceous, elony;ate-oval, roiiglily punctured ; punctures brown. 

 Head elono^ate, smooth in front; middle lobe hardly extending beyond 

 the lateral lobes. Rostrum extending to the liind cox;c ; lip black. An- 

 tennae slender, less than half the length of the body ; joints successively 

 increasing in length ; first extending a little in front of the head. Thorax 

 in front with a smooth band, of which the fore bonier is a curved pale tes- 

 taceous line; sides and a slender stripe also pale testaceous ; hind angles 

 forming two long acute slightly recurved spines. Seutelluni with a slender 

 pale testaceous strijie, on each side of which there is a brown |)atch ; tij) 

 also brown. Pectoral keel well developed. Ahdonien l)eneaih slightly 

 keeled, with two incomplete macular brown stripes; spine extending to the 

 middle coxce. Tore wings clouded with brown around a smooth transverse 

 pale testaceous spot in the disk ; membrane cinereous. Length of the 

 body 3j lines. 



It has most affinity to A. punctata, from which it may be distinguished 

 by the spines of the thorax.

17. ACANTHOSOMA ASPERA. 



T'eslacea, langi-omiia, nigra punctata ; caput elongatum, lobo medio luhos 

 lalrrales perpaullo superanie ; thorax spinis duabus rufis longii 

 validis vix rccurvis ; venter subcarinatus, coxas medias atlingens ; 

 pedes sat graciles ; membrana cinerea. 



Testaceous, elongate-oval, thinly and roughly punctured ; punctures 

 mostly black. Head elongate; middle lobe extending very little beyond 

 the lateral lobes. Rostrum extending a little beyond the hind cox:c ; tip 

 black. AntennsB slender, a little more than half the length of the body; 

 first joint extending a little beyond the front of the head ; second as long 

 as the third ; fourth a little sliorter than the third ; fifth black, testaceous 

 towards the base, shorter than the fourth. Hind angles of the thorax 

 forming two red long stout acute very slightly recurved and ascending 

 spines. Pectoral keel much developed. Abdomen beneath slightly keeled ; 

 spine extending to the middle coxae. Legs rather slender. Membrane of 

 the fore wings cinereous. Length of the body 1^- lines. 



It has most affinity to A. unignttata, from which it may be dis- 

 tinguished by the much broader thoracic spines.
