TENEBRIONID.E. ^ALPHITOBIUS. 11 



of the headj and a deep channel across the crown : thorax subquadraie : 

 elytra with 10 punctured strife on each, the first abbreviated." — Curtis, I. c. 



Found in London amongst flour ; probably a mere variety of the 

 foregoing. 



GENUS CCCCXXVIII.— Alphitobius mihi. 



Aniennce short, robust, slightly clavate, 11-jointed, basal joint thick, curved, 

 slender at the base, second minute, third as long as the two following united, 

 which, with the sixth, are transverse, four following also transverse, pro- 

 duced within, apical one globose. Palpi maxillary, with the terminal joint 

 incrassate and obliquely truncate : mentum subquadrate : head semicircular, 

 clypeus margined: thorax transverse: body elongate-ovate; wings ample: 

 legs short ; femora robust ; anterior tibise slightly dilated, and finely ser- 

 rated externally; tarsi heteromerous, with simple joints. 



This genus differs from Uloma, not only by the diversity in the 

 structure and proportions of the articulations of the antennae, but by 

 the general dissimilarity of the external form and colouring ; and the 

 sexes closely resemble each other, which, in Uloma, is not the case. 



Sp. 1. picipes. Piceo-niger, subtus, ore, antennis pedibusque ferrugineo-cas- 

 taneis, thoracis lateribus medio dilatatis. (Long. corp. 2§ lin.)

 Curtis, viii. p/. 363. 



Above shining, pitchy-black, sometimes inclining to castaneous, thickly and 

 finely punctured : head with a transverse impression at the base of the 

 clypeus, which is entire: thorax subquadrate, with the lateral margins some- 

 times dilated in the middle : elytra depressed, rather delicately punctate- 



fSp. 2. mauritanicus. Piceo-niger, subtus, ore, antennis pedibus, clypeo antice 

 thoracisque angulis anticis piceis, thorace antice angustiori. (Long. corp. 

 3 lin.) 



Te. maviritanica. Fabricius. S. E. i. 149. — Ul. mauritanica. Curtis, fo. 363. 



Above shining pitchy-hlack, minutely but somewhat sparingly punctured : head 

 with a transverse impression at the base of the clypeus, thorax subquadrate, 

 narrowed anteriorly : elytra rather deeply punctate-striated : body beneath, 

 mouth, antennse, legs, clypeus in front and anterior angles of the thorax, 

 and sometimes the apex of the elytra pitchy-castaneous ; occasionally atro- 

 piceous. 



This species has also been captured in London and its vicinity, in 

 repositories of flour and meal.
