directed inwards, a lateral and sutural narrow stripe, and an arcuate band, abbreviated 

 in front and behind, at the posterior portion of each elytron ; all these bands are very 

 narrow, and if the posterior one is fancied joining the sublateral band at each end, the 

 ring-like shape of the type would be produced. The entire insect is of a testaceous 

 colour, the third and fourth joints of the antennae are of equal length, the thorax has 

 the anterior angles not produced and is impunctate, the elytra have a distinct flattened 

 margin and are finely punctured, the head is impunctate, and the eyes are closely 

 approached.

Although I have not seen the type of (E. familiaris, the description given by Von 

 Harold of that species agrees so closely with the insect in Mr. Baly's collection that 

 I have no doubt about their identity. In the Mexican specimens each elytron has 

 eight black spots, placed in two longitudinal rows (one discoidal, the other marginal) ; 

 in a specimen from Guatemala the spots are reduced to six, and those at the margin 

 are nearly joined ; the head in the latter insect is black behind, testaceous in front, 

 while the Mexican specimens have an entirely pale fulvous head, thus showing that no 

 reliance can be placed on colour only as a distinctive character in the species of this genus.

32. (Edionychis discoidea. (Tab. XXIV. fig. 11.) 



Ovate, convex, fulvous ; thorax testaceous, impunctate ; elytra distinctly punctured, flavous, the suture and six 

 elongate spots (placed longitudinally on each elytron) fulvous. 



Length 3 lines. 



Head impunctate at the vertex, the space between the eyes narrow, the latter large, the lower part of the face 

 testaceous ; antennae entirely fulvous, the third joint distinctly shorter than the fourth ; thorax with the 

 anterior and posterior margins straight, the sides rounded towards the apex only, straight at the base, the 

 anterior angles produced into a short tooth ; scutellum dark fulvous ; elytra convex, nearly parallel, closely 

 punctured, the punctuation more distinct anteriorly, a sutural band, constricted at and below the middle, 

 two elongate short stripes at the base, two below the middle, and two small spots near the apex, fulvous ; 

 underside and legs fulvous.

There is only a single specimen of this species before me, and it is possible that it 

 may be a variety of one or other of the species described by Von Harold, although in 

 the pattern of the elytra it approaches (E. seriata.
