424 On a new Genus and Species of Cerambycldje. 



side, marked off from clypeus by a distinct arcuate groove ; 

 eyes rather coarsely gianulate, eraarginate, the lower lobes 

 large ; anteniise about three fourths the length of body, stout, 

 first joint slightly curved, gradually thickened to apex, third 

 shorter than fourth or following, these angulate in front of 

 apex ; pronotum transverse, armed with a short conical 

 tubercle at middle of each side, and three obtuse tubercles on 

 disk ; mesonotum without stridulatory area ; elytra feebly 

 convex, semitransparent, polished, obtusely rounded at apex, 

 with a short spine on each side at suture ; anterior coxa3 

 strongly transverse, but having their acetabula closed behind 

 by extension inwards of epimera to meet the prosternuni, 

 acetabula of middle coxae extending to epimera ; posterior 

 legs much longer than anterior or intermediate legs, their 

 femora reaching to apex of elytra, first joint of posterior tarsi 

 almost as long as the following two united ; first abdominal 

 segment almost as long as the following three together. 



Allied to Megacmlus, Lac, but with larger and more 

 coarsely granulated eyes : elytra longer and not dehiscent at 

 the apex; femora less thickened and the anterior coxal cavities 

 closed bebind. 



I have dedicated this genus to my friend C. J. Gahan, 

 the well-known authority on the Longicornia and an ever 

 helpful adviser to other workers. 



Gahania Simmondsi, sp. n. 



cJ . Head, antennse, thorax, body beneath, and legs pale 

 brownish ochraceous ; eyes black ; elytra pale shining 

 ochraceous, the basal area and sutural margins pale brownish 

 ochraceous, the subcostal areas behind middle distinctly paler ; 

 head finely somewhat sparingly punctate, coarsely rugulose 

 on disk between eyes, centrally, finely, longitudinally sulcate 

 on posterior disk and between the antennal bases, front longly 

 pilose ; pronotum coarsely punctate and granulose, strongly 

 transversely depressed behind anterior margin, a much 

 narrower and finer transverse impression before basal margin, 

 tubercles as in generic description, of the three discal the 

 central is smaller and situate a little behind the others, the 

 conical lateral tubercles have their apices black ; elytra 

 polished, semitransparent, sparingly finely punctate, the 

 punctures more distinct on the darker basal area ; the first 

 three joints of the antennse have outwardly a few long hairs, 

 and the lateral margins of the pronotum are longly sparingly 

 pilose ; body beneath and legs somewhat thickly pilose. 



Long., c?, 23 mm.
