Elytrorum dimidium basale pallide pubescens, maculam magnam circa scutellum 

 nigricantem includens, post hoc elytra fascia nigricante vel fuscescente irregulari sig- 

 nata, parte apicali pallide tomentosa, plus minus nigro- vel fusco-notata. Pronotum 

 saepius rufescens vel ex parte rufescens. 



A', blacklninii var. su/nra/is no\\ 



Elytra, ut in praecedenti varietate, fascia nigricante irregulari postmediana ornata, 

 sutura usque ad basim sat late nigricante, vittam longitudinalem cum fascia postmediali 

 conjunctam formante.

(23) Xyldobius bcddardi, sp. nov. 



Nigricans, antennarum articulis 2 basalibus vel compluribus rufis, rarius obscuri- 

 oribus, elytris basim versus rufo-bimaculatis, maculis rufis sub tomento aureo vel 

 flavescenti abditis, tibiis nigricantibus aut obscuricoloribus. Caput subtiliter densius 

 granulatum, oculis mediocribus, late distantibus. Antennae sat fortiter elongatae, 

 maris, quam elytra, distincte longiores, sed elytris pronotoque una conjunctis baud 

 aequales, feminae, quam elytra evidenter breviores, articulo maris sexto cum sequen- 

 tibus fortiter elongate, feminae articulis eisdeni sat elongatis, maris tamen brevioribus. 

 Pronotum, a latere visum, supra convexum et parum inaequale, haud nitidum, pallide 

 tomentosum. Elytra fortius elongata, subtiliter striata, stria secunda cum tertia sola 

 apicaliter haud confluente, sed saepe cum quinta vel cum alia exteriore conjuncta, et 

 tertiam quartamque vel complures alias strias includente. Long. 3 mm. 



This species is somewhat variable, and sometimes bears a strong superficial resem- 

 blance to A', ashnicadi. It Is, however, a less smooth insect, with a much duller 

 pronotum, unless this be very much rubbed. The red spots towards the base of the 

 elytra are best seen when the elytra are viewed from the apex ; in dorsal aspect the 

 tomentum conceals the colour. They vary in size, and, as the yellow tomentum is 

 developed on them, in some examples nearly the whole basal half of the elytra is 

 covered with this tomentum. The latter fades to greyish, and is usually brighter and 

 more extensive in the females. Towards the apex of the elytra a second pair of incon- 

 spicuous red spots is sometimes present, the tomentum behind the anterior spots being 

 dark coloured, as also at the apex of the elytra, this dark tomentum being traversed 

 usually by a more or less extensive arc of pallid tomentum, whether the posterior red
