XXIII. Additions to the Rhynchotal fauna of Central 

 America. By W. L. Distant, F.E.S. 



[Read October 7th, 1903.] 



Mv last contribution to our knowledge of the Rhynchotal 

 fauna of Central America appeared in the pages of our 

 Transactions for 1900 (p. 687). Tlie following descriptions 

 and notes refer to a small collection recently sent me by 

 Prof. P. Biolley, and which was made in Costa Rica. It 

 contained three new species, and two others not enumerated 

 in the " Biolooia Centrali Americana." 



HETEROPTERA. 

 Family PENTATOMID^E. 



CYDNINAE. 

 Cyrtomenus vestigiatus, sp. n. 



Pieeous, coriuin more or less piceous-brown ; legs, antenn?e and 

 rostrum, pale castaneous ; head broad, rounded, lateral lobes some- 

 what transversely rugose, lateral margins of the central lobe strongly- 

 defined, lateral lobes not meeting in front of central lobe, and 

 thus cleft at their apices ; pronotum with a strong transverse im- 

 pression near middle, this impression and the lateral and anterior 

 margins, sparingly, strongly, linearly punctate, a few coarse punctures 

 on anterior disk of posterior lobe ; scutellum very sparingly but 

 very coarsely punctate, its apex impunctate, and distinctly posteriorly 

 depressed ; corium somewhat thickly and finely punctate ; membrane 

 pale ochraceous, longly passing abdominal apex ; rostrum reaching the 

 intermediate coxaj, its apex pieeous ; intermediate and posterior 

 femora with a few coarse lateral punctures ; tibice with outer series 

 of strong pieeous spines, inwardly longly hirsute. 



Long. 8 to 9 millim. 



Hal. Costa Rica, San Jose (Biolley). 



Taken at electric lamps. 



Allied to C. mirahilis, Perty, from which it differs by its 

 shorter and more robust form, and its more sparsely and 

 deeply punctate scutellum.
