RHYNCHOPHORA MALAYANA 295 



Tlieo^aiiia. 



Rostrum elongatum, lineare, a capite discretum ; aerobes sub-medianae, 

 infra rostrum conni ventes. Antenna3 breves; scapus oculum vix attingeus. 

 I'rothorax ampliatus, basi bisinuatus. Scutellum distinctum. Elytra sub- cor-- 

 diformia. Pedes graciles, antici longiores; femora mutica linearia, antica 

 clongata; tibiae rectae; tarsi anteriores dilatati. Pectus integrum. Abdomen 

 segmentis duobus basalibus ampliatis. 



The nearest ally of this genus appears to be Pseudocholus 

 which, however, has a different facies, thicker femora armed 

 with a small tooth beneath , anterior tarsi not dilated , and a 

 scape nearly reaching the eye. There is no ocular lobe but its 

 place is bordered by short silvery hairs. It is perhaps as well 

 to mention that Theogama is one of the names of Proserpine. 



333. T. lugubris, n. sp. (Tav. 3, f. 1). Oblongo-ovata, nigra, vix ni- 

 tida; caput parvum, retractum ; oculi rotundati, tenui ter granulati; rostrum 

 vix arcuatum; clava antennarum elongato-elliptica; protliorax convexus, 

 utrinque rotundatus, apice tubulatus, sat confertim punctatus; scutellum 

 transversum, paulo excavatum ; elytra protliorace basi vix latiora, lineatim 

 striata, interstitiis planatis, vage sat for titer punctatis, basi juxta scutel- 

 lum, macula alba oblonga notata; corpus infra dense albo-squainosum;

Ilab. Celebes (Kandari), Becca?'i. 



Zena.. 



Rostrum tenue, a capite determinatum ; scrobos antemedianae , obliquae, 

 infra rostrum conniventes. Antennae modice elongates; clava ovata, di- 

 stincta. Oculi tenuiter granulati. Prothorax convexus , basi bisinuatus , lobis 

 ocularibus obsoletis. Elytra protliorace paulo latiora. Pygidium conspicuum. 

 Pectus haixd canaliculatum. Coxae anticae separatae; femora valida, mutica; 

 tibise rectae, sulcata; imguiculi basi connati. 



Allied to Cynethia which has short antennae, subhnear fe- 

 mora, canahculate and toothed beneath, flexuous tibiae, and 

 free claws but approximate throughout. Oxynia , inter alia, has 

 a long filiform rostrum and divergent claws. The type of the 

 genus is variable as usual as to the lines: in many individuals 

 there is a short one at the base on the third interstice, and 

 one or two , longer or shorter, on the fourth and fifth.
