2. Airora pollens, sp. n. 
Cylindrica, nigra, nitida, capite prothoraceque fortiter punctatis; elytris striatis, striis sat fortiter punctatis, 
punctis elongatis, inter se sat remotis, interstitiis vix transversim convexis. 
Long. 14-15 millim. 
Hab. Mexico, Tepanistlahuaca (Sallé), Temax in North Yucatan (Gaumer). 
I have seen only two examples of this insect, and have hesitated whether I should 
treat it as a variety of large size of A. yucatanica; I think, on the whole, it is more 
likely to prove distinct. ‘The joints of the club of the antenne are rather larger, and 
the pits containing the sensitive pubescence are larger, especially the one on the ninth 
joint. The sculpture is a little coarser. 
The two examples are male and female. In the former sex the small sexual 
punctures on the ventral plates are more numerous and definite than they are in 
A, yucatanica. 
3. Airora longicollis. 
Trogossita longicollis, Guér. Icon. Regne Anim. iii. p. 200°. 
Airora clivinoides, Reitter, Verh. Ver. Brinn, xiv., Abhandl. p. 19°. 
Airora longicollis, Léveillé, Bull. Soc. Ent. Fr. 1889, p. xlv. 
Hab. Mexico 2, Cordova, Jalapa (Hége); GuaTEMALA, Pantaleon, Mirandilla (Cham- 
pion); Nicaragua, Chontales (Janson).—Co.ombia, Bogota? ; Brazit ?. 
We have received a series of about twenty examples of this species; it is readily 
distinguished from A. centralis by its small size and slender form, and by the fact 
that the elytra are finely striate, the striae somewhat remotely punctured, and the inter- 
stices bearing a series of fine remote punctures along the middle of each. I cannot 
detect any character whereby to identify the sexes. 
4, Airora centralis, sp.n. (Tab. XIII. figg. 2; 2a, antenna.) 
Cylindrica, nigra, sat nitida; capite opaco, sat parce et subtiliter punctato ; prothorace suboblongo, sat crebre 
et fortiter punctato ; elytris seriatim fortiter sat numerose punctatis, interstitiis planis, parce subtilissime 
punctatis. 
Long. 12-13 millim. 
Hab. Mexico, Orizaba (Sal/é) ; Guatemaua, El Reposo, Pantaleon Torola (Champion); 
Panama, Bugaba (Champion). 
This may be distinguished from the other species here enumerated by the dull and 
less coarsely punctate head, as well as by the elytra being not at all striate, the very 
definite punctures being arranged in regular rows, and being smaller near the apex. 
We have received seven examples; but 1 do not detect any sexual distinctions. 
A. centralis agrees in many respects with Reitter’s description (Verh. Ver. Briinn, 
xiv., Abhandl. p. 20) of the Antillean A. striato-punctata; but that species is said to 
have the interstices subcostate, and a deeply impressed sutural stria.
