156 F. Stoliczka — Monograph of Indian Passalidce. [No. 3, 



Dr. Eedtenbacher (Coleopteren, Reise Oest. Fregatte Novara, 1867, 

 p. 49) gives Mastachilus politus^ from Madras. There is a specimen 

 of that species in the Vienna Museum collection, marked Ind. or., 

 and is most likely the one referred to by Redtenbacher. I very much 

 doubt, however, that it is Indian. It was probabl}^ received from the 

 Madras Museum, or from a collector, during the stay of the Novara 

 at Madras. My reason for doubting the correctness of the Indian 

 locality is based upon an observation which I made. I asked the Curator, 

 the late Capt. Mitchell, for the loan of any specimens of Passali, he might 

 have in the Madras Museum. I was promptly responded to, and shortly 

 after received four specimens of Passali. Two proved to belong to a new 

 species JPleurarms hrachyphylluSy and the two others were Solenocyclus 

 exaratus (known from Madagascar) and Mastachilus polyphyllus (from 

 Australia). t After detailed inquiry Capt. Mitchell informed me, that the 

 two first specimens (distinguished by numbers attached to them) were truly 

 Indian, from the Nilgherries, but that the localities of the two others were 

 unknown. They had been received from some old European collection. It 

 seems to me very probable that something similar happened with the speci- 

 men of M. politus, obtained by the Novara at Madras. 



Kaup describes Macrolinus Waterhousei and Episphenus Moorei from 

 Ceylon. I have not seen either of these. 



Fifth group. Aceeai^. 



Of the five genera. Laches, Gonates, Aceraius, Cetejus, and Basilianus, 

 only the third and fifth have as yet been found in India ; they are common 

 and numerous, and the specific number of five will, I am sui-e, run short 

 for what is in this case really required for specific determination, unless the 

 genera are somewhat differently defined and grouped. 



Of the other genera I have examined a few interesting species. Among 

 these is one which Kaup would probably call the first, moderately convex, 

 species of Laches, and the largest species of Cetejus ; both answer exactly the 

 characters of the respective genera. I add descriptions of the two new species J 

 in a foot note. 



* Originally described by Burmeister from Van Diemen's Land. 



t The Vienna Museum possesses two specimens of polyphyllus from China. 



X Laches geacilis, n. sp. Total length 26, width of head 5-5, of prothorax 7'5, 

 of shoulders 7 '6, length of elytra 15 m.m. Whole body moderately convex. 



Upper lip almost quite straight in front ; left jaw barely longer than the right 

 one. The three first lobes of the antennae short, the fourth slightly shorter than the 

 fifth. Clypeus on its posterior half rugosely punctated ; the short horn rises from the 

 anterior central edge of a transversely elongated, smooth protuberance ; from it proceed 

 under a narrow angle the frontal carinse, each terminating in an elongated smooth tu- 

 bercle, or rather short ridge, connected by a very fine carina. The marginal tubercles of 

 the clypeus are pointed, depressed, placed nearer to each other than the width of the
