Group-CRYPTORHYNCHID^. 



Nothaldonus, 



Nov. gen. 



Body Aldonus-like, structurally nearly similar to Aldonus~\)ui 

 differing therefrom as follows : 



Pectoral canal profound, extending beyond the anterior coxae, and 

 limited behind by the broad elevated border of the mesosternum. 

 Ocular lobes represented by obtuse angulations, just where the side 

 of the thorax and front margin of the sternal canal unite. Eyes 

 more finely facetted. The scrobes commence before the middle, 

 becoming broader, though still as deep, close to the front of the 

 eyes ; there is also a groove extending from the point of antennal 

 insertion to the apex ; the scrobes are alike in both genera. 



This genus is instituted for the reception of No. 859, which 

 becomes Nothaldonus peacei. 



Mesoreda. 



Nov. gen. 



Rostrum longer than thorax, almost parallel-sided, very slightly 

 narrowed towards the base, scarcely at all arched. In Oreda it is 

 much shorter, twice as thick, and somewhat expanded near the base. 

 Scrobes deep, o! uniform depth and breadth, or nearly so, from their 

 commencement (one-third of entire length from apex) to the eyes. 

 Antenna longer than in Oreda, more slender ; joints 3-7 very short 

 and transverse; club more elongate, basal two joints large and 

 quadrate. Pectoral canal narrow, its front angles widely rounded, 

 without the conspicuous spiniform process seen in Oreda, and limited 

 by the raised front edge of the mesosternum ; the middle piece of 

 the mesosternum is not elevated as in Oreda. Tibia less curvedly 

 produced at extremity, with much smaller spurs. 



This genus is instituted for the more systematic location of two 

 species (Nos. 865 and 1625) formerly referred to- Oreda. These be- 

 come Mesoreda setigera and If. orthorhina respectively. 



Acalles. 



2173. A. veratrus, 'n.s. Convex, compact, broadly oval; densely 

 covered with small, roundish, depressed, greyish-yellow scales and 

 upstanding squamiform setae; black, tarsi and antennae reddish- 

 black. 



Rostrum a little dilated towards the apex, which is smooth and on 

 a lower level than behind, it is limited by a strongly-curved suture, 

 the space behind squamose. Scape short, setose ; first two joints 

 of funiculus elongate, about equal ; club finely pubescent, ovate. 

 Thorax considerably narrowed towards the front, 'which is contracted 

 to width of head, base nearly truncate ; its sculpture concealed by 

 the squamosity. Scutellum invisible. Elytra appearing slightly 

 broader than thorax at base, owing to the numerous setae on the
