 MADAGASCAK. 



By JOHN W. SIIIPP. 



Actinophonis grandidieri sj). uov. 



DAUK fuscous, with a greenish tinge and reflection. Clypeus six-dentate ; 

 anterior margin reflexed ; very thickly and closely punctured, the punctures 

 being much coarser and run together round the margins ; teeth rather pointed and 

 impnnctate. Two transverse carinae extend from the eyes towards the centre of the 

 head, but disappear on disc. Head sligljtly raised on disc between the carinae, 

 and a rather deep cleft separates the liasal teeth of the cl3-peus from the others; 

 a small patch of short pitchy Ijrown liairs are situated in the lobes of the four 

 front teeth. 



Thorax very thickly and closely punctured with rather deep well-defined 

 punctures, and with a slight trace of a longitudinal smooth line on disc, which, how- 

 ever, is sometimes quite obsolete. Lateral margins rounded ; anterior angles sharply 

 obtuse, posterior angles being almost obsolete ; lateral margins deeply creuulated the 

 whole length and fnrnished with a row of pitchy hairs ; anterior margin finely and 

 smoothly emarginate. Posterior margin crenulate the whole lengtii, witii the 

 exception of a small portion adjoining tlie scutellary region ; scutellary projection 

 obsolete. Lateral cicatrices obsolete. 



Elytra finely granulo-asperate, with some moderately large shallow jiores 

 scattered over the interstices. Elytra six-striate, with the striae composeil of a 

 number of shallow pores run together, giving the striae the appearance of being 

 quite smooth. Sides rounded, scarcely cordate, rather depressed on disc ; lateral 

 margins strongly emarginate, bicarinatc, and smooth. Humeral proniint'iices not 

 very distinct. 



Pygidium emarginate, twice as wide as long, and very sparingly punctured. 



Anterior and posterior femora smooth, with a few large punctures scattered 

 over the thick portions and margins, the punctures being furnished with short light 

 brown hairs. 



Anterior tibiae four-dentate ; disc inipnnctate. but with a raised crenulated 

 carina which terminates in a short raised tooth at the base of the basal tooth, the 

 carina being provided with a row of short porrcct hairs. The iudentatinns between 

 the teeth on the exterior margin are scallojjed. 



Posterior tibiae long, curved, and fringed with short hairs ; posterior coxae 

 produced into a short sharp spine. 



.\bdoraen almost impnnctate on disc, rather finely punctured at sides. 



Mesosternum almost inipunctate, a small longitudinal depression on disc, and 

 I)roduced to an obtuse inipunctate keel, whicli is thickly punctured on the sides and 

 sparingly furnished with short pitchy liairs.
