LEMA. 21 
an elytral depression near the suture below the base (this being absent in L. bicincta) ; 
the punctures within this depression are distinctly deeper and larger than the others, 
the latter gradually diminishing towards the apex, where the interstices are more or 
less convex. The posterior band of the elytra is as broad as the anterior one, and 
nearly straight (in ZL. dicincta it is strongly curved), and does not extend to the lateral 
margin. The ground-colour of the thorax and elytra of L. chiriquensis is generally paler 
than in L. bicincta; the antenne extend to about half the length of the elytra; the 
thorax is but moderately constricted at the sides, the transverse basal groove is also not 
very deep, and a few fine punctures may be seen (under a strong lens) on the middle 
of the disc; the rest is as in LZ. bicincta. I have examined eighteen specimens, all 
agreeing in the above particulars. 
30 (s). Lema forreri. (Tab. XXXV. fig. 16.) 
Fulvous, the head, the basal joints of the antenne, and the breast black; elytra very deeply punctate-striate, 
a transverse band at the base, and another below the middle, blue; posterior femora with a black spot. 
Length 24-3 lines. 
Head impunctate, black, the grooves round the eyes very deep; antenne short and robust, not extending beyond 
the base of the elytra, fulvous, the basal joint black, the second and third joints very short and nearly 
equal; thorax reddish-fulvous, but moderately constricted at the middle, the basilar sulcation not very 
deep, the middle of the disc with several rows of minute punctures which disappear towards the base ; 
scutellum black; elytra with a short depression below the base, very deeply, strongly, and closely punc- 
tured on the anterior portion, more finely so behind, the interstices convex towards the apex, the anterior 
blue band sinuate at its posterior margin near the suture, and extending to the extreme lateral margin, 
the posterior band of equal width, but not reaching to the margin; the underside and legs fulvous, the 
breast and a spot at the middle of the posterior femora black. 
Hab. Mexico, Presidio (forrer). 
The elytral pattern of this species is again similar to that of L. dicincta and several 
others; the deep punctuation of the elytra, however, in connection with the short and 
robust antenne, separate L. forrert from any of its allies. The spot on the posterior 
femora is present in three out of the four specimens before me. 
30 (c). Lema cyaneo-fasciata. 
Head and thorax rufous, the antenne and legs fulvous; elytra strongly punctate-striate, flavous, a transverse 
band at the base, and another below the middle, blue; breast black; abdomen flavous. 
Length 24-3 lines. 
Hab. Mexico, Oaxaca (Salié). 
Although at first sight the present insect seems identical with LZ. bicincta, L. forreri, 
and other similarly-marked species, the colour of the head and of the antenne does not 
allow of its identification with either. The two specimens before me, although obtained 
at the same locality, differ somewhat from each other—in one the antenne are compa- 
ratively short and robust, and entirely fulvous, and the elytra are very strongly 
punctured anteriorly, but the punctuation gradually diminishes in depth towards the
