four joints fuscous. Thorax one-third longer than broad at the base, its 

 apical border slightly produced, anterior angles obsolete ; upper surface 

 smooth, impressed at the base with a single fovea ; middle of disk im- 

 pressed with a double longitudinal row of very minute punctm-es, only 

 visible with a lens. Elytra much broader than the thorax, not quite 

 three times its length, sides parallel, above veiy convex, gibbous at the 

 base ; each elytron covered with about ten ill-defined interrupted rows 

 of large deeply impressed punctures, the interspaces thickened ; the 

 piceous patches, the most considerable of which occupies the middle 

 of the outer disk and is attached to the lateral border, form over the 

 disk an ill-defined shining and impimctate network. Body beneath 

 stained on the neck and sides of thorax and breast with fuscous; 

 abdomen clothed with short adpressed silvery hairs ; all the segments 

 as far as the peniiltmiate marked with three piceous spots, the anal 

 segment having only a single patch. Thighs incrassate, narrowed at 

 their base, hinder pair scarcely shorter than the abdomen ; four anterior 

 tibiae annulated with fuscous below tlieu- middle. 



Criocerls gibha. (Plate XIII. fig. 3.) 

 C. subelongata, parallela, nucea, nitida; antennis subfiliformibus, sat 

 robustis, articulis cylindricis ; thorace elougatulo, lateribus medio con- 

 strictis, apice producto, laevi, disci medio tenuissime biseriatim pimc- 

 tato ; elytris oblongis, basi sat gibbosis, profunde substriato-punctatis, 

 striis interruptis, iis prope suturam ab ante mediimi fere ad apicem 

 omuino deletis; corpore subtus, femoribus incrassatis (basi excepta), 

 tibiarimi apice antennisque (his basi praetennissis) piceis. — Long. 4 lin.

Very similar to the preceding species, but differing in the greater 

 leno-th and in the form of the antennae, in the longer body, and in the 

 entirely different arrangement of the punctation of the elytra. Head 

 rather shorter than in C. Dromedarius ; antennae longer than half the 

 body, robust, subfiliform, indistinctly incrassate towards the apex ; four 

 or five terminal joints slightly incrassate, second, third, and fourth joints 

 short, submoniliform. Thorax equal in length, but more regularly con- 

 stricted on the sides, the constriction commencing at the angles and 

 extending the whole length of the side ; in the other species the con- 

 striction commences a short distance from the angles, and is more 

 abrupt ; disk impunctate, with the exception of a double longitudinal 

 row of very fine punctures do^Ti the middle. Elyti-a oblong, parallel ; 

 the gibbosity slightly less raised than in the fonner species ; the punc- 

 tures on the sm-face as large and as deeply impressed, but an-anged in a 

 different manner ; the striae from being more intennipted are less distinct, 

 and in addition the whole inner disk, from the base of the gibbosity 

 nearly to the apex of the elytra, is entirely' free from punctures ; the 

 punctures here and there confluent. Thighs similar to those of C. 

 Ih-omedarius ; body beneath sparingly covered with pubescence.
