 tiore, carinulis brevibus trausversis serie media ornato, lateribus iuor- 

 dinatiin asperatis, disco medio elevato, utrinque oblique declivi, fascia 

 apicali basali et media (interrupta et sa?pe deficieute), Uavo-pubescen- 

 tibus ; elytris apice breviter acumiuatis, fasciis tribus, margine apicali, 

 scutelloque flavo-pubescentibus ; subtus flavo-pubescens, protboracis 

 lateribus, episteruis metatboracis antice, coxisque omnibus obscuris ;

Oregon ; collected by Lord Walsingham. Of the same form 

 as N. erythrocejihalus, with the short carina? of the prothorax 

 fewer and less developed, the front one of the medial series being 

 longer but scarcely higher than the others, the apex is distinctly 

 margined ; the middle fascia of the prothorax is feeble in one 

 specimen, and slightly interrupted in the other, the apical and 

 basal fasciae are broad, and unite beneath at the presternum. 

 The elytra] fasciae are broad, the first and second are straight 

 and transverse, the 3d inclines slightly backwards from the suture. 

 The under surface is covered thickly with yellow hair in % , except 

 on the flanks of the prothorax, and the front half of the side 

 pieces of the metathorax ; in the ? the yellow hair is much 

 thinner, and the ground color appears to be ferruginous. The 

 hind thighs of the % extend beyond the tip of the abdomen, but 

 not in the 2. 



525. N. interruptllS. Fusco-piceus, pubescens, protborace latitu- 

 dine longiore, lateribus late rotundatis, apice marginato, basi angustiore, 

 carinis transversis tribus ornato, lmo pone apicem longiore, alteris pone 

 medium brevibus, dense punctato et parce asperato, gutta parva basali 

 media flavo-pubescente ; elytris apice singulatim rotundatis, fasciis tri- 

 bus scutelloque flavo pubescentilms ; lma nee marginem nee suturam 

 attingente, 2nda et 3ia marginem non attingente, bac obliqua ; subtus 

 obscure ferrugineus, episternis metatboracis postice, segmeutoque ven- 

 trali lmo flavo-maculatis. Long. 10 mm. 



One specimen ; California, collected by Mr. J. Behrens, and 

 communicated to me by Dr. Horn. This species is also allied to 

 N. erythrocephalus, and in well-preserved specimens the markings 

 beneath would perhaps be similar; but in the one examined 

 there are only two spots of yellow pubescence on each side; one 

 on the hind part of the metathoracic episterna, the other at the 

 side of the 1st ventral segment on its hind margin. 

 14 June, 1873.
