Cryptocephalus guatemalensis (p. 49). 
To the localities given, add:—Mexico, Presidio, Ventanas (Forrer), Durango city, 
Guadalajara in Jalisco (Hége); Guatemaua, Chimaltenango (Conradt). 
Cryptocephalus xanthospilus (p. 50). 
To the locality Mexico, add:—Colima city (Hége), Tepetlapa in Guerrero (Hi. 
Smith), Panistlahuaca (Salé). 
I give a renewed description of this species, that of Suffrian being no doubt based 
upon insufficient material :— 
Dark brown ; thorax finely rugose, the anterior margin narrowly and the lateral margins broadly, as well as 
two narrow spots at the base, bright yellow ; elytra coarsely and closely punctate-striate, the basal margin, - 
a narrow central transverse band, and the apex (two small brown spots excepted) yellow. 
Length 24 lines. 
Head punctured at the vertex, brown, a narrow transverse space between the eyes flavous; antenne more 
than two-thirds the length of the body, the basal five joints fulvous, the others nearly black ; thorax 
about one half broader than long, very strongly narrowed in front, the sides rounded, the surface finely 
rugosely punctured throughout, dark brown, the anterior margin very narrowly, the lateral margins 
broadly, yellow, the base with a short oblique yellow stripe on each side, the stripes not connected with 
each other; scutellum brown ; elytra slightly narrowed posteriorly, the punctures very deep and closely 
placed, but interrupted in the centre by the transverse flavous band (across which the fifth and seventh — 
rows form short oblique rows of three punctures each) and again at the apex (so that only the remnants 
of the fourth and fifth and sixth and tenth rows of punctures, joined posteriorly, are visible); the under- 
side and legs dark brown, a spot at the side of the breast above the epipleurs and a narrow margin to 
the ventral segments yellow. 
Specimens from the above localities agree very closely with Suffrian’s description. 
The elytral punctuation varies somewhat in our specimens, these having a short, strongly 
oblique row of three or four punctures intersecting the central yellow band, a character 
not mentioned by Suffrian. The elytra may be described as yellow, with two transverse 
regular bands, one before, the other below the middle, and two small spots within the 
apex of each, brown. 
27 (a). Cryptocephalus complicatus. (Tab. XXXVII. fig. 17.) 
Flavous, variegated with brown ; thowax dark brown, with eight large yellow spots placed transversely ; elytra 
coarsely subgeminate-punctate-striate, flavous, this colour separated by longitudinal and transverse irre- 
gular stripes ; femora brown, with a large yellow spot near the apex. 
Length 2-24 lines. 
Head flavous, a spot on the vertex, a short central line, and the base of the antenne brown; antenne two- 
thirds the length of the body, the basal five joints fulvous, the others black ; thorax more than twice as 
broad as long at the base, greatly narrowed in front, the posterior angles acutely produced, the surface 
almost imperceptibly punctured, dark brown, with four flavous spots placed along the anterior and four 
others along the posterior margin, the base with a short but distinct depression on each side near the 
scutellum ; scutellum dark brown; elytra with the rows of punctures arranged in pairs, and placed in dark 
brown strie below the middle, the fifth row connected at the apex with the eighth, but in front of this 
making a wide turn inwards (so that it closely approaches the preceding rows and then turns back again 
towards the shoulder), the broader space caused by this change of direction of the fifth row having some
