1883.] BEETLES OF THE FAMILY EROTYLID^. 83 



Murray's collection and named by Crotch E. obliquata: it is only 

 half the size of that species ; the striae are much more obsolete. 

 The whole of the abdomen is rufous ; and the posterior fascia is 

 recurved more on the margin and less on the suture. The di- 

 stinction of the alutaceous surface of the thorax appears to me also 

 to be a good character. 



Two specimens in Murray's collection, purchased by me, are 

 labelled n. sp. in Crotch's handwriting. 



19. AULACOCHILUS INCLYTUS. 



Niger, supra ccerulescens, nitidus, capite thoraceque fere glabris ; 

 elytris valde convexis, singulis maculis duabus magnis subrotun- 

 datisfulvis, striis obsoletissime punctatis, fere obliteratis. 



Long. lOg-llniiUim. 



Hah. Philippine Islands, Panaon {Semper). 



This species is distinguished from all its congeners (except A. 

 dories) by having /our large subquadrate or roundish red spots, of 

 which the hinder one is not arcuate, on its elytra. Of these this one 

 is separable by the blue shining thorax, which is scarcely visibly 

 punctate ; the head has a few scattered punctures, which are distinct 

 under a good glass. The elytra are somewhat cordate ; the front 

 spot touches the base and just reaches the scutellum, it leaves the 

 humeral callus and margin black ; the hind spot is squarish, some- 

 times transverse, very nearly reaching the suture and margin. The 

 underside is almost or quite black, without any of the blue tint 

 observable in the whole upper surface. 



This species is not in the Crotch collection at Cambridge. 



20. AuLACOCHiLUs AGABOiDEs. (Plate XVIII. fig. 10.) 



Ovatus, niger, nitidus; capite distincte, thorace minute hand pro- 

 funde punctatis; elytris tenuiter pimctato-striatis, singulis maculis 

 duabus, una basilari intus tridentata, altera ante apicem valde 

 arcuata ; abdomine rufo, segmento basali nigra. 



Long, y millim. 



Hab. Philippine Islands, E. Mindanao, N. Luzon {Semper, 

 Cuming). 



The ground-colour of this species is quite black ; the basal spot 

 occupies the whole base, extending in an oblique direction from 

 the scutellum across the shoulder, but leaving the reflexed edge 

 of the margin black ; it emits three rather long denticulations, be- 

 tween the first and second of which it is excavated rather deeply; 

 the hind spot is undulated on its basal, produced on each side of its 

 apical margin ; both the spots are usually pale yellow. The elytra 

 are finely punctate-striate, the interstices very finely, scarcely visibly 

 punctate ; the abdomen pitchy-red excepting its basal segment, or 

 very nearly quite black. I have seen one specimen of this in the 

 Crotch collection at Cambridge. 



The specimens taken by Cuming were obtained by me from Mr. 

 Waterhouse's collection.
