DESCRIPTION OF THREE NEW SPECIES OF THE GENUS 

 PHAN^US, MACLEAY. 



BY B. G. NEVINSON", M.A., F.Z.S. 



Phan^us Elohei, n. sp. 



Dark blackish-blue. Clypeus entire, rugosely punctate. Head horn long, 

 erect, recurved at the apex, incrassate just above the base, strongly punctate. Thorax 

 with the anterior angles sharp, slightly produced ; the sides minutely granulate, 

 faintly flushed with green ; the disc quite flat, sparsely vermiculate-granulate, with 

 no tubercles or elevations, having nearly circular margins, the marginal carinse 

 elevated at their bases, forming two blunt prominences, between them a shining, 

 scarcely punctate, triangular space, with a shallow central sulcus, and enclosing two 

 indistinct basal foveolse. Elytra striate, the strise foveolate at their bases, interstices 

 broad and flat, minutely punctate. Pygidium dark blue, closely punctate. The 

 under-side blackish-blue, the metasternum shining, closely punctate, with a central 

 sulcus and two shallow basal impressions. Anterior tibiae tridentate. Pubescence 

 and antennae dark piceous. Long., 21 mm. 



Mexico, Jalapa (Flohr). 



Mas effem. — Head horn produced to a sharply pointed tubercle. Thoracic 

 surface strongly punctate, with a very small circular disc just above the anterior 

 margin, and two distinct basal foveolae. 



Female.— With a strong carina on the vertex of the head, the usual three 

 tubercles thereof barely indicated. Thorax strongly punctate, with a broad central 

 prominence, limited in front by a faint carina, and with a depression, nitid and more 

 sparsely punctate on either side. A distinct impression runs from the carina to the 

 base, where there are two rather large foveolae. The striae of the elytra in the un- 

 developed males and in the females are rather broader than in the perfect male, the
