Diagnosis. Small to medium-sized, moderately elongate species; body reddish to reddish brown, usually with distinct dark markings on elytra (see Variation below); head wide, with large eyes; tempora strongly and nearly evenly narrowing posteriad; pronotal disc evenly convex, distinctly punctured; pronotal horn moderately long, mostly rather robust / wide (variation) with wider apical and smaller lateral lobules on margins; horn crest at most very slightly indicated, dorsal surface of horn rather evenly vaulted and densely covered with distinct rugules; punctation in basal half of elytra rather distinct, punctures dot-like, simple, with smooth margins.

Male characters (Dinajpur, MNHN). Elytra clearly modified apically, slightly subtruncate in dorso-caudal view, with distinct gland opening near rather moderately indicated lateral angle; legs simple; abdominal sternum VII moderately emarginate postero-medially ( Fig. 27 View Figs ); tergum VIII forming simple arched sclerite ( Fig. 28 View Figs ); aedeagus as figured ( Figs. 29, 30 View Figs ).

Variation. Body length (J ♀) 2.9–3.9 mm. Rather variable in prominence of dark markings of elytra (cf. Figs. 61 View Figs versus 62); basal / humeral, lateral and subapical spots may be interconnected, forming conspicuous cruciform marking, or separate and reduced, with subapical spot completely absent. Rather variable in proportions of pronotal horn, its lateral margins with 3–5 lobules; apical lobule may be narrow, evenly shaped or wide, asymmetrical and partly fused with one of subapical lobules.

Distribution. Bangladesh ( BONADONA 1978), India: West Bengal, Uttarakhand, Uttar Pradesh, Himachal Pradesh, Maharashtra; Nepal ( UHMANN 1983; KREKICH- STRASSOLDO 1913, 1928; TELNOV 2003; mostly as N. peregrinus   ); Pakistan.

Remarks. KREKICH- STRASSOLDO (1913) described N. noctivagus   from two female syntypes, originating from different localities and collections: ‘Bengalen’ (NHMW), ‘Ganges-Delta’ (Indian Museum in Calcutta). Its species identity is fixed herein by description of the male characters. The relevant male specimen, originating from a longer series collected in Bangladesh ( BONADONA 1978), agrees perfectly with the examined syntype.

As stated by KREKICH- STRASSOLDO (1914), N. peregrinus   was described from a single male specimen collected at light in Calcutta and deposited in the Indian Museum in Calcutta. One of the above listed three specimens from northern India (Uttarkhand, Kumaon), deposited in Krekich-Strassoldo’s collection in the NHMW, bears a red type label. It is surely not a type, but probably additional specimen used by KREKICH- STRASSOLDO (1928) for subsequent description of the male characters and variability in colouration.

I have not attempted at examination of the holotype of N. peregrinus   . The newly proposed synonymy is based on examination of male specimens from various localities and regions. They were found to be identical with the figures provided by KREKICH- STRASSOLDO (1914b, 1928).

The specimen collected by A. Riedel in Rishikesh (SMNS) bears an identification label ‘ Notoxus andrewesi   ’ by G. Uhmann.
